Which event is not associated with the Revolutionary War?

The Louisiana Purchase is an event that occurred in 1803, well after the Revolutionary War had already concluded in 1783. This significant land acquisition, where the United States purchased territory from France, expanded the nation's geography and influence but is not connected to the events or causes leading up to the American Revolutionary War.

In contrast, the Boston Tea Party, the signing of the Declaration of Independence, and the Battles of Lexington and Concord were all pivotal moments that directly contributed to the conflict between the American colonies and Great Britain. The Boston Tea Party was a protest against British taxation, the Declaration of Independence formally announced the colonies' break from Britain, and the Battles of Lexington and Concord were the first military engagements of the war. Understanding this context highlights why the Louisiana Purchase stands apart from these Revolutionary War events.
