Which act, enacted by Jefferson, prohibited American trading ships from leaving the U.S.?

The Embargo Act of 1807 was designed to respond to British and French interference with American shipping. Specifically, it aimed to pressure those nations to respect American neutrality during the Napoleonic Wars by prohibiting American ships from trading with foreign ports. Jefferson believed that this would mitigate the risk of conflict and protect American interests at sea while avoiding war. Unfortunately, the act had severe economic repercussions for the United States, leading to widespread discontent and hardship, particularly in New England, where maritime commerce was essential to the economy. This act reflects Jefferson's commitment to diplomacy over military engagement, even though it ultimately proved to be a controversial measure.
