Maryland is a state in the Mid-Atlantic region of the United States. It shares borders with Virginia to the south, West Virginia to the west, Pennsylvania to the north, and Delaware and the Atlantic Ocean to the east. The nation's capital, Washington, D.C., is also to its southwest.
Maryland is one of the smallest states by land area, ranking ninth. However, it is the fifth most densely populated state. Its capital city is Annapolis, and its largest city is Baltimore.
Europeans first explored Maryland's coast in the 1500s. Before that, various Native American tribes, mostly the Algonquian peoples, lived there. Maryland was one of the original Thirteen Colonies. It was founded by George Calvert, who wanted to create a safe place for Catholics. King Charles I of England named the colony after his wife, Henrietta Maria of France.
In 1649, Maryland passed a law called the Maryland Toleration Act, which promoted religious freedom. The state's early economy relied on plantations, especially for growing tobacco. This led to many indentured servants and enslaved Africans being brought to the colony. Maryland played important roles in the American Revolutionary War. Even though it was a state where slavery was allowed, Maryland stayed with the Union during the American Civil War. Its location near Washington D.C. made it very important strategically. After the Civil War, Maryland grew during the Industrial Revolution, thanks to its ports and railroads.
Since the 1940s, Maryland's population has grown a lot. It is now one of the most crowded U.S. states. Maryland has a very diverse economy, including manufacturing, healthcare, and technology. It is also one of the most multicultural states. Many people from Africa, Asia, Central America, and the Caribbean live here. Maryland's important role in U.S. history means it has many historic landmarks.
The state has different landscapes. Western Maryland has parts of the Appalachian Mountains. The central area has rolling hills, and the eastern side includes a large part of the Chesapeake Bay. Because of its varied geography, Maryland is sometimes called America in Miniature. Its culture and history mix elements from the Mid-Atlantic, Northeastern, and Southern parts of the country.

Maryland's Story: A Look Back
Early Days: The 1600s
How Maryland Began
George Calvert, also known as the 1st Baron Baltimore, wanted to start a colony. He asked King Charles I of England for land between Massachusetts and Virginia. After George Calvert passed away, his son, Cecilius Calvert, received the official charter on June 20, 1632.
The new "Maryland Colony" was named to honor Henrietta Maria of France, King Charles I's wife. Lord Baltimore first thought of naming it "Crescentia," meaning "land of growth." But the King suggested "Terra Mariae," which means "Mary Land," and that name was chosen.
The first capital of Maryland was St. Mary's City. This city was located on the north side of the Potomac River. The county around it was the first one created in the colony.
Lord Baltimore's first settlers arrived in March 1634. His younger brother, Leonard Calvert, was the first governor. They made their first permanent home at St. Mary's City. They bought the land from the local Native American chief, who wanted to trade with them. St. Mary's was Maryland's capital for 60 years, until 1695. More settlers came, and their tobacco crops made the colony profitable.
Religious Challenges for Catholics
Maryland was founded as a safe place for Roman Catholics from England. However, Catholics were still a minority in Maryland, making up less than 10% of the population.
In 1642, some Puritans moved from Virginia to Maryland. They founded a settlement called Providence, which is now Annapolis. A disagreement over Kent Island led to fighting. In 1644, a Puritan named William Claiborne took Kent Island. His friend, Richard Ingle, took over St. Mary's. They used religion to gain support. The two years from 1644 to 1646 were called "The Plundering Time." During this time, Jesuit priests were captured and sent back to England.
In 1646, Leonard Calvert returned with troops and took back St. Mary's City. In 1649, the government passed the "Act concerning Religion." This law gave religious freedom to all Christians who believed in the Trinity.
In 1650, the Puritans rebelled again. They removed Catholics from the legislature. Religious conflict returned. The Puritan government banned both Catholicism and Anglicanism. Mobs burned down Catholic churches in southern Maryland. This Puritan rule lasted until 1658. Then, the Calvert family regained control and brought back the Toleration Act.
After England's Glorious Revolution in 1688, Maryland made Catholicism illegal. In 1704, the Maryland General Assembly passed laws against Catholics. They could not run schools. They also limited how much property religious groups could own. This situation continued until after the American Revolutionary War. Wealthy Catholic landowners built secret chapels on their properties to practice their faith.
Solving Border Disputes (1681–1760)
Maryland's original charter gave it land north of the Potomac River up to the 40th parallel. But King Charles II of England later gave a charter for Pennsylvania. This new grant said Pennsylvania's southern border was the same as Maryland's northern border, the 40th parallel. The problem was that the King and William Penn thought the 40th parallel would be near New Castle, Delaware. Instead, it was north of Philadelphia, where Penn wanted to build his capital.
Talks began in 1681 to fix this. A compromise was suggested in 1682. But Penn then received more land, which is now Delaware. Penn argued that Maryland's charter only applied to unsettled lands. Dutch settlements in Delaware were there before Maryland's charter. The dispute lasted for almost 100 years. It was continued by the families of William Penn and Lord Baltimore.
The border dispute with Pennsylvania led to a conflict called Cresap's War in the 1730s. Fighting started in 1730 and grew worse. Maryland sent military forces in 1736, and Pennsylvania did the same in 1737. The fighting stopped in May 1738 when King George II stepped in. He made them negotiate a cease-fire. A temporary agreement had been made in 1732.
Negotiations continued until a final agreement was signed in 1760. This agreement set the border between Maryland and Pennsylvania. It became known as the Mason–Dixon line. Maryland's border with Delaware was based on a Transpeninsular Line and the Twelve-Mile Circle around New Castle.
The 1700s: Revolution and New Beginnings
Most early English colonists came to Maryland as indentured servants. They worked for several years to pay for their trip. At first, there wasn't a clear difference between indentured servants and enslaved Africans. Both white and Black laborers often lived and worked together.
Many free Black families moved to Delaware, where land was cheaper. As fewer indentured laborers came from England, Maryland planters brought in more enslaved people. Racial divisions became stronger.
Maryland was one of the Thirteen Colonies that rebelled against British rule in the American Revolution. On February 2, 1781, Maryland was the last of the 13 states to approve the Articles of Confederation. This document created the United States as a united, independent nation. Maryland also became the seventh state to join the Union after approving the new federal Constitution in 1788.
In December 1790, Maryland gave land to the federal government. This land, chosen by President George Washington, became part of the new national capital, Washington, D.C.. This land came from Montgomery and Prince George's counties.
The 1800s: War and Growth

After the American Revolution, many Maryland planters freed their enslaved people. The number of free Black people in the Upper South grew a lot by 1810. Famous abolitionists Harriet Tubman and Frederick Douglass were born into slavery in Maryland during this time.
During the War of 1812, the British tried to capture Baltimore. The city was protected by Fort McHenry. While the fort was being bombed, Francis Scott Key wrote the song "The Star-Spangled Banner." This song later became the national anthem.
The National Road, later called U.S. Route 40, was approved in 1817. It was a federal highway from Baltimore to St. Louis. The Baltimore and Ohio Railroad (B&O) was the first railroad in the U.S. It opened its first section in 1830 between Baltimore and Ellicott City. In 1852, it was the first rail line to reach the Ohio River from the East Coast.
Maryland During the Civil War

Maryland remained with the Union during the American Civil War. This was partly due to its population and federal actions. In 1860, almost half of Maryland's African Americans were free.
To help ensure a pro-Union government, President Abraham Lincoln had some pro-slavery politicians arrested. This included the Mayor of Baltimore. He also suspended certain civil liberties and ordered cannons placed on Federal Hill overlooking Baltimore.
In April 1861, federal troops were attacked while marching through Baltimore. This event, known as the Baltimore riot of 1861, was the first bloodshed of the Civil War. About 85,000 Marylanders joined the Union army, while others joined the Confederate Army. The biggest battle in Maryland was the Battle of Antietam on September 17, 1862. It was one of the bloodiest battles of the war. Although it was a tactical draw, it was a major turning point for the Union.
After the Civil War
A new state constitution in 1864 ended slavery in Maryland. The state was then called a "Free State." After new laws gave voting rights to Black men, Maryland extended voting rights to non-white males in 1867.
The Democratic Party quickly regained power in Maryland. They replaced the 1864 Constitution with the Constitution of 1867. After the Reconstruction era ended in 1877, Democrats found ways to prevent Black people from voting. This included intimidation and later, new laws. However, Black people and immigrants fought against these efforts. Maryland's Black population was part of a Republican group elected to state government from 1896 to 1904.
Compared to other states, Black people in Maryland were better established before and after the Civil War. Many were free before the war and owned property. Half of the Black population lived in cities. Literacy was high among Black people. As Democrats tried to exclude them, voting campaigns helped educate Black voters on how to resist. However, white people did enforce racial segregation and Jim Crow laws. These laws lasted until the mid-1960s.
Baltimore grew a lot during the Industrial Revolution. Its seaport and good railroad connections attracted many European immigrants. Many factories were built in the Baltimore area after the Civil War. Businessmen like Johns Hopkins and Enoch Pratt founded important city institutions. These include a university, a library system, a music conservatory, and an art museum.
Cumberland was Maryland's second-largest city in the 1800s. Natural resources and railroads helped it become a major manufacturing center.
The 1900s: Modern Maryland
The Progressive Era in the late 1800s and early 1900s brought political changes. Laws were passed to make voting fairer. These included standard ballots and private voting booths. They also started primary elections to choose candidates. These changes made it harder for less educated people to vote. Black people fought against these efforts, with groups teaching voters.
Black people defeated three attempts to take away their voting rights. They formed alliances with immigrants to resist Democratic campaigns. Bills to remove voting rights in 1905, 1907, and 1911 were stopped. This was largely due to strong opposition from Black voters. Black people made up 20% of voters, and immigrants made up 15%. It was hard for the legislature to create laws that only hurt Black voters without also affecting immigrants.
The Progressive Era also improved working conditions. In 1902, Maryland regulated mines. It banned child labor for children under 12. It also made school attendance required. The state passed the nation's first workers' compensation law. This law was first overturned but was later rewritten and passed in 1910.
The Great Baltimore Fire of 1904 burned for over 30 hours. It destroyed 1,526 buildings across 70 city blocks. More than 1,231 firefighters worked to control the blaze.
When the U.S. entered World War I in 1917, new military bases were built. These included Camp Meade and the Aberdeen Proving Ground. Existing facilities like Fort McHenry were also greatly expanded.
In 1923, a congressman criticized Maryland for not passing Prohibition laws. In response, a newspaper editor called Maryland the "Free State." This nickname became popular.
Maryland's cities and rural areas had different experiences during the Great Depression. The "Bonus Army" marched through the state in 1932 on their way to Washington, D.C. Maryland started its first income tax in 1937 to fund schools and welfare.
Passenger and freight steamboat service, once very important on the Chesapeake Bay, ended in 1962.
Baltimore was a major war production center during World War II. Large operations included Bethlehem Steel's Fairfield Yard, which built ships. Glenn Martin was an aircraft manufacturer.
Maryland's population grew after World War II. Starting in the 1960s, suburbs grew around Washington, D.C., and Baltimore. The state began to feel more like the Mid-Atlantic region. Farmland was replaced by new communities. The Interstate Highway System was built, changing how people traveled. In 1952, the Chesapeake Bay Bridge connected the eastern and western parts of Maryland for the first time.
After WWII, Maryland's regions saw economic changes. Heavy manufacturing in Baltimore declined. In western Maryland, jobs in industry, railroads, and coal mining decreased. On the lower Eastern Shore, large farms and poultry operations became common. In Southern Maryland, tobacco farming almost disappeared due to new housing and a state program to buy out tobacco farms.
Baltimore started urban renewal projects in the 1960s. These projects aimed to bring people back to the city. Some projects led to the breakup of old neighborhoods. However, some older areas near the harbor were renovated and became popular.
Maryland's Geography and Nature
Maryland covers an area of about 12,407 square miles (32,133 square kilometers). It is the 42nd largest state and the 9th smallest. It is similar in size to Belgium.
What Maryland Looks Like




Maryland has many different types of land, which is why it's called America in Miniature. It has sandy dunes in the east with seagrass. There are also low marshlands with lots of wildlife near the Chesapeake Bay. In the Piedmont Region, you'll find rolling hills with oak forests. To the west, there are pine groves in the mountains.
Maryland's northern border is with Pennsylvania. To the north and east is Delaware. The Atlantic Ocean is to its east. To the south and west, across the Potomac River, are West Virginia and Virginia. Washington, D.C. is in the middle of the border with Virginia. It sits on land that was once part of Maryland. The Chesapeake Bay almost cuts the state in half. The counties east of the bay are called the Eastern Shore.
Most of Maryland's waterways flow into the Chesapeake Bay. A tiny part of western Garrett County drains into the Mississippi River. The eastern part of Worcester County drains into Maryland's Atlantic coastal bays. A small part of the northeast corner drains into the Delaware River. The Chesapeake Bay is so important that some people want to change the state's nickname to the "Bay State."
The highest point in Maryland is Hoye Crest on Backbone Mountain. It is 3,360 feet (1024 meters) high. This is in the southwest corner of Garrett County. Near the town of Hancock, the state is very narrow. Less than 2 miles (3.2 km) separate its northern and southern borders.
Parts of Maryland are in different geographic regions. The Delmarva Peninsula includes Maryland's Eastern Shore counties. Western Maryland is part of Appalachia. Much of the Baltimore–Washington area is in the Coastal Plain.
Maryland's Land and Rocks
Earthquakes are rare and small in Maryland. This is because the state is far from major earthquake zones. The 2011 Virginia earthquake was felt in Maryland. Buildings here are not designed for strong earthquakes, so they can be easily damaged.
Maryland has no natural lakes. All lakes in the state were built by people, mostly with dams.
Plants of Maryland
Maryland has many different plants. Enough rain falls each year to support various types of plants. These include seagrass and reeds. There are also huge white oak trees, which are the state tree. They can grow over 70 feet (21 meters) tall.
Around Chesapeake Bay and on the Delmarva Peninsula, you'll find forests typical of the southeastern Atlantic coast. Moving west, the central part of the state has a mix of northeastern and southeastern forests. The Appalachian Mountains in western Maryland have different types of forests.
Many non-native plants are grown in Maryland. Some are for decoration, like the crape myrtle. Others are unique, like hardy palm trees in warmer areas. However, invasive plant species like kudzu and Japanese stiltgrass can harm native plants. Maryland's state flower, the black-eyed susan, grows widely across the state.
Animals of Maryland

Maryland has a lot of white-tailed deer. This is especially true in the woody and mountainous western parts of the state. Sometimes, there are too many deer. Other mammals found here include black bears, bobcats, foxes, coyotes, raccoons, and otters.
There are wild (feral) horses on Assateague Island. People believe they are descendants of horses that escaped from Spanish shipwrecks. Every July, these horses are rounded up and swim across a shallow bay. They are then sold at Chincoteague, Virginia. This helps manage their population on the small island. The children's book Misty of Chincoteague made these ponies famous.
The Chesapeake Bay Retriever dog breed was developed for water sports and hunting in the Chesapeake area. It was the first retriever breed recognized by the American Kennel Club in 1878. The University of Maryland, Baltimore County uses it as their mascot.
Maryland's reptiles and amphibians include the diamondback terrapin turtle. This turtle is the mascot of the University of Maryland, College Park. The state bird is the Baltimore oriole, which is also the mascot of the MLB team, the Baltimore Orioles. Over 435 other bird species have been seen in Maryland.
The state insect is the Baltimore checkerspot butterfly.
Maryland's Environment
Maryland has joined with nearby states to improve the Chesapeake Bay. The bay's aquatic life and seafood industry are threatened by development and pollution. This pollution comes from fertilizers and farm animal waste.
In 2007, Forbes.com ranked Maryland as the fifth "Greenest" state. Maryland uses less toxic waste per person than most states. In April 2007, Maryland joined the Regional Greenhouse Gas Initiative (RGGI). This group works to reduce greenhouse gas emissions. In March 2017, Maryland became the first state with natural gas reserves to ban fracking.
Maryland's Climate

Maryland has many different climates. This is due to changes in elevation, how close it is to water, and protection from cold winds.
The eastern half of Maryland, including Ocean City and Annapolis, has a humid subtropical climate. This means it has hot, humid summers and cool to cold winters.
The Piedmont region, including northern Baltimore and Frederick, gets more snow. Temperatures below 10°F (–12°C) are less common here. From the Cumberland Valley westward, the climate becomes more humid continental climate.
In western Maryland, higher areas like Allegany and Garrett counties have a humid continental climate. This is because of their higher elevation.
Maryland gets a lot of rain, from 35 to 45 inches (890 to 1140 mm) annually. Most parts of the state receive 3.5 to 4.5 inches (89 to 114 mm) of rain each month. Average annual snowfall varies from 9 inches (23 cm) near the coast to over 100 inches (250 cm) in the western mountains.
Because it's on the Atlantic Coast, Maryland can be affected by tropical cyclones. However, the Delmarva Peninsula and North Carolina's outer banks offer protection. Major hurricanes are rare. Maryland usually gets the weaker remnants of tropical storms. The state averages 30–40 days of thunderstorms a year and about six tornado strikes annually.

Cities and Metro Areas
Most people in Maryland live in the central part of the state. This includes the Baltimore metropolitan area and Washington metropolitan area. These areas are part of the larger Baltimore–Washington metropolitan area. The largest number of people live in and around Baltimore, Maryland's biggest city, and the suburbs of Washington, D.C.. Historically, many Maryland cities grew along the Fall Line. This is where rivers have rapids and waterfalls. Annapolis, the state capital, is an exception. It is on the Severn River, near where it flows into the Chesapeake Bay.
The Eastern Shore has fewer people and is more rural. The same is true for western Maryland. The two westernmost counties, Allegany and Garrett, are mountainous and have few residents. They look more like West Virginia and Appalachia. Both eastern and western Maryland have important regional cities. These include Ocean City and Salisbury on the Eastern Shore. In Western Maryland, there are cities like Cumberland and Frostburg. Southern Maryland is still somewhat rural. However, suburban growth from Washington, D.C., has increased since the 1960s. Important towns there include Lexington Park and Waldorf.

How Maryland is Governed

Maryland's government follows its own state constitution. Like other U.S. states, Maryland has power over matters within its borders. This power is limited by the Constitution of the United States.
Power in Maryland is split into three parts: the executive, legislative, and judicial branches. The Maryland General Assembly makes the laws. It has two parts: the Maryland House of Delegates and the Maryland Senate. Maryland's governor has a lot of power over the state budget. Many of Maryland's counties also have a lot of independence.
Most government work happens in Annapolis, the state capital. However, some government offices are in Baltimore. Elections for governor and most state offices are held every four years, during midterm election years.
The judicial branch includes the Maryland District Court, which is in every county and Baltimore City. There are also 24 Maryland Circuit Courts. These courts handle major civil and criminal cases. The appeals court is the Appellate Court of Maryland. The highest court is the Supreme Court of Maryland. The justices of the Supreme Court of Maryland wear unique red robes.
