From 1754 to 1763 the British fought the French over the land between the Mississippi and the Appalachians. The British won the war. However, the British were now broke. They had to make more money. Parliament decided to tax the colonists, who until then weren't paying taxes.
In response to the lack of funds following the French and Indian War, the British Parliament passed many new laws and taxes on the colonists in order to gain more revenue and cut current costs. One of these acts was the Quartering Act. Passed in 1765, this act stated that colonists had to house, feed, and supply British soldiers for free. This enraged many of the colonists because it violated their privacy.
On December 5, 1770, colonists were rioting outside the customs building because of the newly declared Townshend Acts. The crowd was throwing snowballs at the British soldiers outside. Suddenly, the Redcoats opened fire, killing five colonists. For many of the colonists, this event pushed them over the fence on wether or not England had to go.
After the Boston Massacre, many colonists were furious with the British. One night over 100 people gathered and rowed to a ship in Boston Harbor, where they threw over seventeen million dollars worth of the king's tea into the harbor.
In response to the Boston Tea Party, Parliament legislates a series of laws known in the colonies as the Intolerable Acts. These laws closed off New England to exports outside of the British Empire and closed off Boston harbor. However, because the other colonies were forced to support New England, it brought the colonies closer together.
The social unrest, in response to the Intolerable Acts, leads to British soldiers march on Lexington and Concord, villages outside Boston, in order to capture colonists' supplies, ammunition, and Sam Adams, the rebels' leader. However, their plan fails because the Minutemen are ready. While the Redcoats return to Boston, Minutemen kill more than 250 soldiers.
