The correct answer is D. The Hartford Convention led to the demise of the Federalist Party.

Explanation:

The Hartford Convention was an event in Hartford in 1814-1815, where federalists met to discuss their dissatisfaction with the War of 1812, and the political problems that arose as the federal government grew stronger.

During the meeting, the abolition of the Three-Fifths Compromise, which gave so-called "slave states" more power in the US Congress, was demanded, along with the provision that there be at least two-thirds majority in the Congress in deciding on the entry of new states into the United States, war declarations, and legislation that restricted trade. The Federalists also discussed their dissatisfaction with the Louisiana Purchase and the 1807 embargo. But a few weeks later, when the news of Andrew Jackson's victory in the Battle of New Orleans swept across the northeast, the federalists lost their role as a significant party in US politics.

united states reinforcements contributed greatly to three allied victories in france at: cantigny (first major american battle), argonne (the largest in the united states military history, involving 1.2 million american soldiers), and château-thierry (one of the first actions under general pershing).
