Explain the events that led to the louisiana purchase and how president jefferson used foreign policy to complete this purchase. what challenges did jefferson face in this event? why did president jefferson authorize the embargo act? how did this act affect america’s economy and citizens?

Louisiana Purchase allowed for more farm land but was not in the president's power: Jefferson was a strict Constitutionalist meaning if it wasn't it the Constitution then he couldn't do it. Purchasing land was not addressed in teh Constitution and therefore he thought he shouldn't. However, Jefferson supported farming and the land would open up that industry. Ultimately he was convinced it fell under his power to create treaties. 

The Embargo Act was used against Britain because they were firing on US ships during the Napoleonic Wars: This act hurt US shipping and trade because Britain was a main trading part. Also they stopped buying from the US stopping the US economy. 

Of the revolutions of 1848.
