Explain the importance of Lewis and Clark’s expedition.

The importance of Lewis and Clark’s expedition was mainly to explore the Missouri River. Over the two year journey, they discovered more landscapes, rivers, Native American tribes, animals, and plants more than any other scientific exploration of the time. Their expedition gave the Americans a better understanding of the land and production of the first accurate maps of the area. The expedition gave the Americans knowledge of what natural resources the land held. Their expedition also started relations with Native American tribes.

Explain how the war in Europe hurt American trade.

The war in Europe hurt American trade because the participants wanted to embargo all trade to their enemies. Trade from America to Europe had to go by sea. The trade passed by Britain, the main enemy of Napoleon, who had the largest navy. Napoleon used other European countries to place a trade embargo on Britain so Britain did the same, this hurt trade to and from America. This especially happened when America declared war on Britain.

What were the causes and effects of the War of 1812?

The House of Representatives wanting to expand into Canada was one cause of the War of 1812. Others include Americans being angered when their sailors got impressed. Americans believed that the British were pushing the Native Americans to fight against the Settlers, which also angered them. Effects of the war were that the Americans’ patriotism was increased. The Native Americans were weakened and the loss of trade encouraged American manufacturing. This also proved that the United States could defend itself.
