Why were the Intolerable Acts so inflammatory among the colonists?

The Intolerable Acts of 1774 was an attempt by the British Crown to use punitive measures against the American Colonists to exert authority over them following a series of insurrectionist incidents sparked by the Boston Tea Party of 1773. The Acts passed by Parliament included: - closing the Boston Harbor to commerce until full restitution was made to the owners. - Canceling the Colony's charter making it a crown colony and imposing martial law under General Thomas Gage. - Provide immunity from local colonial prosecution for Crown officials and allowed the to go on trial in neighboring colonies or England. - Gave Crown Governors the right to requisition buildings to quarter British troops sent to intimidate the colonials. The intolerable acts were the proverbial straw that broke the camels back. These oppressive measures were the excuse needed by the colonists to convene the First Continental Congress in 1774.
