The Intolerable Acts were passed in 1774 to punish the colonists for the Boston Tea Party. There were three major acts involved that angered the colonists.
The first was the Boston Port Bill and it closed the Boston Harbor until the people of Boston paid for the tea that they threw into the harbor. It went into effect on June 1, 1774.
The Administration of Justice Act became effective May 20th and it did not allow British soldiers to be tried in the colonies for any crimes they might commit. This meant the soldiers could do anything they wanted since they would probably not be punished for their crimes.
The Massachusetts Government Act which also took effect on May 20, 1774, restricted town meetings to one a year unless the governor approved any more. The Massachusetts assembly could not meet. The governor would appoint all the officials, juries and sheriffs.
The Quebec Act was established May 20, 1774. This act extended the Canadian borders to cut some of Massachusetts, Connecticut, and Virginia.
There was also the Quartering Act that was established on March 24th. It required the colonial authorities to provide housing and supplies for the British troops.
The Impartial Administration of Justice Act gave British troops freedom from the Massachusetts law. So just like Administration of Justice Act, British troops could do whatever they wanted without worrying about consequences.
These laws made the people in Massachusetts and all the colonists very angry. The Boston Port Act helped to bond the colonies because the Bostonians needed supplies until the port opened back up. The Intolerable Acts also helped the colonies bond together. They joined together in boycotting British goods. This prepared the colonists for their war with the British and to declare their independence.
