What events led up to the Vietnam war
The assassination of Archduke Franz Ferdinand was the main event that led up to the outbreak of World War 1.
WW2 was a total war.
There were many things that led to the revolutionary war. Taxation without representation being one of them, along with the treaty of Paris. Britain started to rule over the 13 colonies in 1763 and wanted to discourage all emigrants (colonists). Of course many of people that lived in the colonies were colonists and did not like their rule. Britain highly raised taxes which led to the Boston tea party of Thursday December 16, 1773. People dressed up as Indians to protect other colonists. This didn't work, and then the Boston Massacre occurred. There is also a lot of confusion about the Rev. war too. Some people think the proclamation of 1763 caused it. No, it didn't that just separated Indians and the colonists from each other.
