In the early 1700s, there was a religious movement in the colonies called the Great Awakening. Preachers such as Jonathan Edwards preached sermons. One of them was called "Sinners in the Hands of an Angry God". The Great Awakening may have led to the thinking used in the American Revolution.
By 1733, there were thirteen colonies. New York City, Philadelphia, Boston, and Charleston were the largest cities and main ports at that time.
From 1756 to 1763, England and France fought a war over their land in America called the Seven Years' War or the French and Indian War, which the British won. After the war, the Royal Proclamation of 1763 said that the colonists could not live west of the Appalachian Mountains. Many colonists who wanted to move to the frontier did not like the Proclamation.
After the French and Indian War, the colonists began to think that they were not getting their "rights as freeborn Englishman". This meant they wanted to be treated fairly by the English government. This was mainly caused by new taxes the British made the colonies pay to pay for the war. Americans called this "No taxation without representation", meaning that the colonists should not have to pay taxes unless they had votes in the British Parliament. Each tax was disliked, and replaced by another which led to more unity between the colonies. In 1770, colonists in Boston known as the Sons of Liberty got in a fight with British soldiers. This became known as the Boston Massacre. After the Tea Act, the Sons of Liberty dumped hundreds of boxes of tea in the sea. This was known as the Boston Tea Party (1773). This led to the British Army taking over Boston. After that, leaders of the 13 colonies formed a group called the Continental Congress. Many people were members of the Continental Congress, but some of the more important ones were Benjamin Franklin, John Adams, Thomas Jefferson, John Hancock, Roger Sherman and John Jay.
In 1776, Thomas Paine wrote a pamphlet called "Common Sense". It argued that the colonies should be free of English rule. This was based on the English ideas of natural rights and social contract put forth by John Locke and others. On July 4, 1776, people from the 13 colonies agreed to the United States Declaration of Independence. This said that they were free and independent states, and were not part of England any more. The colonists were already fighting Britain in the Revolutionary War at this time. The Revolutionary War started in 1775 at Lexington and Concord. Though American soldiers under George Washington lost many battles to the British, they won a major victory at Saratoga in 1777. This led to France and Spain joining the war on the side of the Americans. In 1781, an American victory at Yorktown helped by the French led Britain to decide to stop fighting and give up the colonies. America had won the war and its independence.
In 1781, the colonies formed a confederation of states under the Articles of Confederation, but it lasted only six years. It gave almost all the power to the states and very little to the central government. The confederation had no president. It could not remove Native Americans or the British from the frontier, nor could it stop mob uprisings such as Shays' Rebellion. After Shays' Rebellion, many people thought the Articles of Confederation were not working.
In 1787, a constitution was written. Many of the people who helped write the Constitution, such as Washington, James Madison, Alexander Hamilton and Gouverneur Morris, were among the major thinkers in America at the time. Some of these men would later hold important offices in the new government. The constitution created a stronger national government that had three branches: executive (the President and his staff), legislative (the House of Representatives and the Senate), and judicial (the federal courts).
Some states agreed to the Constitution very quickly. In other states, many people did not like the Constitution because it gave more power to the central government and had no bill of rights. To try and get the Constitution passed, Madison, Hamilton and Jay wrote a series of newspaper articles called the "Federalist Papers". Very soon after, the Bill of Rights was added. This was a set of 10 amendments (changes), that limited the government's power and guaranteed rights to the citizens. Like the Declaration of Independence, the Constitution is a social contract between the people and the government. The main idea of the Constitution is that the government is a republic (a representative democracy) elected by the people, who all have the same rights. However, this was not true at first, when only white males who owned property could vote. Because of state laws as well as the 14th, 15th, 19th, 24th and 26th Amendments, almost all American citizens who are at least 18 years old can vote today.
In 1789, Washington was elected the first President. He defined how a person should act as President and retired after two terms. During Washington's term, there was a Whiskey Rebellion, where country farmers tried to stop the government from collecting taxes on whiskey. In 1795, Congress passed the Jay Treaty, which allowed for increased trade with Britain in exchange for the British giving up their forts on the Great Lakes. However, Great Britain was still doing things that hurt the U.S., such as impressment (making American sailors join the British Royal Navy).
John Adams defeated Thomas Jefferson in the election of 1796 to become the second President of the United States. This was the first American election that was between two political parties. As president, Adams made the army and navy larger. He also got the Alien and Sedition Acts passed, which were much disliked.
In the election of 1800, Jefferson defeated Adams. One of the most important things he did as President was to make the Louisiana Purchase from France, which made the United States twice as big. Jefferson sent Lewis and Clark to map the Louisiana Purchase. Jefferson also tried to stop trade with England and France so that the United States would not become involved in a war the two countries were fighting. Fighting broke out between the United States and England in 1812 when James Madison was President. This was called the War of 1812.
One of the problems of this period was slavery. By 1861, over three million African-Americans were enslaved in the South. This means that they worked for other people, but had no freedom and received no money for their work. Most worked picking cotton on large plantations. Cotton became the main crop in the South after Eli Whitney invented the cotton gin in 1793. There were a few slave rebellions against slavery, including one led by Nat Turner. All of these rebellions failed. The South wanted to keep slavery, but by the time of the Civil War, many people in the North wanted to end it. Another argument between the North and South was about the role of government. The South wanted stronger state governments, but the North wanted a stronger central government.
After the War of 1812 the Federalist Party faded away, leaving an "Era of Good Feelings" in which only one party was important, under Presidents James Madison and James Monroe. Under Monroe, the United States' policy in North America was the Monroe Doctrine, which suggested that Europe should stop trying to control the United States and other independent countries in the Americas. Around this time, Congress called for something called the "American System". The American System meant spending money on banking, transportation and communication. Due to the American System, bigger cities and more factories were built. One of the big transportation projects of this time was the Erie Canal, a canal in the state of New York. By the 1840s, railroads were built as well as canals. By 1860, thousands of miles of railroads and telegraph lines had been built in the United States, mostly in the Northeast and Midwest.
