Cambridge is a city in Middlesex County, Massachusetts, United States. It's a suburb of Boston, located right across the Charles River. In 2020, about 118,403 people lived there, making it the fourth-largest city in Massachusetts. Cambridge was named after the University of Cambridge in England, which was important to the city's founders.
Cambridge is famous for its universities. Harvard University, founded in 1636, is the oldest university in the United States. The Massachusetts Institute of Technology (MIT), Lesley University, and Hult International Business School are also in Cambridge.
The area around Kendall Square, near MIT, is sometimes called "the most innovative square mile on the planet." This is because many new technology companies have started there since 2010.
Cambridge was founded in December 1630, making it one of the first cities in the Thirteen Colonies. It played a big role in the American Revolution. In May 1775, about 16,000 American patriots gathered in Cambridge Common. On July 2, 1775, George Washington arrived there to take command of the Continental Army. This is why Cambridge Common is known as the birthplace of the Continental Army.

History of Cambridge
Early Days and Colonial Times
Before Europeans arrived, the Massachusett people lived in the area for thousands of years. They called it Anmoughcawgen, which means 'fishing weir' or 'beaver dam'. European diseases greatly reduced the native population before many English settlers arrived in 1630.
In December 1630, settlers chose this spot because it was safe from enemy ships. The city was first called "the newe towne" or "Newtowne." It was one of the first towns founded by Puritans in the Massachusetts Bay Colony. The original village is now part of Harvard Square.
In 1636, Newe College was founded to train ministers. It was later renamed Harvard College after a generous donor, John Harvard. In May 1638, the town's name changed to Cambridge to honor the University of Cambridge in England. Many early leaders of the colony and the college had studied at the English university.
Over the years, parts of Cambridge became separate towns, like Newton and Lexington. By the time of the American Revolution, most people lived near Cambridge Common and Harvard College.
The Revolutionary War and Growth

On July 3, 1775, George Washington took command of the Patriot soldiers in Cambridge Common. This event is seen as the start of the Continental Army. In January 1776, Henry Knox brought cannons from Fort Ticonderoga, which helped Washington force the British Army to leave Boston. After the war, many properties belonging to British supporters were taken over.
Between 1790 and 1840, Cambridge grew quickly. New bridges and roads, like the West Boston Bridge (1792), connected Cambridge directly to Boston. This made it easier to travel and helped new industries and homes develop.
In the mid-1800s, Cambridge became a center for famous writers, including the "Fireside poets" like Henry Wadsworth Longfellow. Cambridge became a city in 1846. The main business area moved from Harvard Square to Central Square.
By the late 1800s, Cambridge had many new neighborhoods. Industries like brick-making and ice-cutting grew. Thousands of immigrants came to work in these new factories. The New England Glass Company, founded in 1818, was once the world's largest glass factory.
Modern Cambridge: From Industry to Innovation
By 1920, Cambridge was a major industrial city with almost 120,000 residents. Famous companies like Carter's Ink Company and many candy makers were located here. Main Street was even called "Confectioner's Row."
After the Great Depression and World War II, Cambridge's industries declined. The city then became more focused on education and research. Harvard University became even more important. When Radcliffe College for women was founded in 1879, Cambridge attracted many talented female students. MIT's move from Boston to Cambridge in 1916 also made Cambridge a top intellectual center.
In the 1980s, many high-tech companies started in Cambridge. Companies like VisiCorp (which made the first spreadsheet software) and Lotus Development were based here. Today, Kendall Square is a hub for tech giants like Google, Microsoft, and Amazon.
Cambridge also became a leader in biotechnology. In the 1970s, the city set up rules for new genetic research, which helped companies like Biogen and Genzyme grow. Now, many major biotech and pharmaceutical companies have offices and labs in Cambridge.
In the 1990s, a system called "rent control" ended in Cambridge. This change led to more housing construction and higher property values in the city. Cambridge is now known for having one of the most expensive housing markets in the Northeastern United States.
Since 1985, Cambridge has been a "sanctuary city," which means it has policies to protect immigrants.
