The stamp act was yet another law that made the colonists pay a tax for printed items such as books. They made people pay those taxes by making people put these stamps on printed items, and make the colonists pay for the stamp, which was something they didn't even want. People knew if a colonist didn't pay the taxes if the printed items didn't have stamps.
The Boston Massacre was an event that was ignited when the colonists taunted the soldiers. A bunch of colonist protesters, called Patriots, were protesting because they didn't like the British troops put outside their city. The soldiers were put outside because of some taxation issues. Thomas Preston, who was the leader of the troops at boston, told the troops to get their guns ready. The colonists thought the troops were getting ready to fire at them, so the started throwing snowballs at the troops in retaliation. Then the troops actually started shooting at the colonists. Five men died. Eventually at the end of the Boston Massacre these troops were brought to justice. They had a letter M engraved into their fingers as (a very, very, silly one, but definitely not a painless one) punishment. That was the end of the Boston Massacre.
