History of Philadelphia
Early Native American Peoples
Before Europeans arrived in the 1600s, the Philadelphia area was home to the Lenape Indians. Their village was called Shackamaxon. They were also known as the Delaware Indians. Their lands were along the Delaware River and the Hudson Valley.
Most Lenape people were forced out of the region in the 1700s as European colonies grew. Diseases like smallpox also weakened their communities. Many Lenape moved west. After the American Revolutionary War, the U.S. government moved most remaining Lenape to Indian Territory in what is now Oklahoma.
Colonial Beginnings

Europeans first came to the Philadelphia area in the early 1600s. Dutch settlers built Fort Nassau in 1623. Later, Swedish settlers created the colony of New Sweden in 1638. The Dutch took control of the Swedish colony in 1655.
In 1664, an English fleet captured the Dutch colony. The area became part of William Penn's new colony of Pennsylvania in 1682. King Charles II of England gave Penn the land to repay a debt.
Penn, a Quaker, wanted his colony to be a place where everyone could worship freely. He bought the land from the local Lenape people to ensure peace. Penn made a friendship treaty with Lenape chief Tammany.
Penn named the city Philadelphia, which means "brotherly love" in Greek. He wanted it to be a peaceful place. This tolerance helped Philadelphia grow quickly into an important city.
Penn planned the city with a grid plan to keep houses spread out. This was meant to prevent fires. However, people crowded near the Port of Philadelphia on the Delaware River.
In 1701, Penn made Philadelphia an official city. By the 1750s, it was a major trading center. Benjamin Franklin helped improve city services. He started the first fire company, library, and hospital in the nation.
Philadelphia and the American Revolution

Philadelphia's central location made it a key place for American revolutionaries. By the 1750s, Philadelphia was the largest city and busiest port in British America. It was the second-largest city in the entire British Empire after London.
In 1774, Philadelphia hosted the First Continental Congress. This meeting was held as colonists grew angry with British rule. From 1775 to 1781, Philadelphia hosted the Second Continental Congress.
In what is now Independence Hall, the Declaration of Independence was adopted on July 4, 1776. This document, mostly written by Thomas Jefferson, declared war against the powerful British Army. The Declaration's signing is celebrated every year on July 4th.
After a battle in September 1777, the British Army took control of Philadelphia. The Liberty Bell and other church bells were hidden to prevent the British from melting them down for weapons. The Liberty Bell was hidden in Allentown for nine months.
Two Revolutionary War battles, the Siege of Fort Mifflin and the Battle of Germantown, happened within Philadelphia's city limits. In 1777, the Second Continental Congress adopted the Articles of Confederation in Philadelphia. The Constitutional Convention also met here in 1787 to approve the U.S. Constitution.
Philadelphia served as the capital of the United States for much of the colonial period. It was the capital from 1790 to 1800 while Washington, D.C. was being built. In 1793, a severe yellow fever epidemic killed many people in the city. The U.S. capital moved to Washington, D.C., in 1800.
Philadelphia remained the nation's largest city until 1790, when New York City grew larger. In 1816, the city's free Black community founded the African Methodist Episcopal Church. This was the first independent Black church in the country. New roads, canals, and railroads helped Philadelphia become the first major industrial city in the U.S.
19th and 20th Century Growth
Throughout the 1800s, Philadelphia was home to many industries, especially textiles. Large companies like Baldwin Locomotive Works and the Pennsylvania Railroad were based here. In 1876, the city hosted the Centennial Exposition, the first World's Fair in the U.S.
Many immigrants from Ireland and Germany settled in Philadelphia. They helped lead the first general strike in North America in 1835, winning the ten-hour workday. In the 1840s, thousands of Irish immigrants came to the city, fleeing the Great Famine.
In 1854, the city limits expanded to cover all of Philadelphia County. Later in the 19th and early 20th centuries, immigrants from Russia, Eastern Europe, and Italy arrived. Many African Americans also moved to the city from the southern U.S. during the Great Migration.
By 1950, Philadelphia's population reached over two million. However, it then began to decline as industries changed and people moved to the suburbs. In the late 1970s, neighborhoods began to be revitalized. Areas like Old City and Society Hill were restored.
New skyscrapers were built in Center City starting in the 1980s. Immigrants from around the world began to move to Philadelphia. This helped the city's population start growing again in the 21st century.
