In 1754 the Seven Years War broke out. The British and French were fighting for the Ohio River Valley, which had access to the Mississippi River, which was a very helpful trade route. They officially called war in 1756. The Treaty of Paris was signed in 1763, declaring victory and peace for the British.
The Stamp act was created to gain money back that they lost from the French and Indian War. The Stamp Act is basically for every piece of paper you buy, you have to buy a stamp as well to make the piece of paper legal. This act ended up in a riot because "no taxation without representation".
In 1765 the British Parliament passes the Quartering Act. The Quartering Act says that if there is no room in the barracks for officer and soldiers, it is lawful for them to be placed in uninhabited houses or other buildings, and be supplied with food, bedding, candles, etc. They don't have to pay for what they ate or used.
The Boston Massacre was in 1770. What happened was the British were trying to protect the King's money. The people around were taunting the guards and one accidentally fired, and the other guards caught on and fired too. Five people ended up dying, but the soldiers were just trying to protect the King's money.
The Boston Tea Party was in 1773. The colonists dressed up as Indians and went to the harbor and dumped 342 crates of tea into the water. That is nearly $1 million in today's money.
Lexington and Concord started in 1775 and lead into the Revolutionary War. For a while the 13 colonies and the British had a lot of tension, especially in Massachusetts. Hundreds of British troops went to nearby Concord to seize an arms cache.
