How did the War of 1812 influence westward expansion of the United States?

A. It ended Native American resistance for the time being.

B. It ended expansion because treaties gave western land to the British.

C. It increased Native American resistance and slowed expansion.

The correct option is

A. It ended Native American resistance for the time being.

Explanation:

The War of 1812 was fought between the United States of America and the United Kingdom of Great Britain and Ireland and its colonies. After the War of 1812, many new territories were opened in the West and the government began to offer land to people who would move there. Soon several new states were formed in addition to the original 13 colonies.

The correct answer is A. It ended Native American resistance for the time being. After the signature of the Treaty of Ghent on December 24, 1814, and the formal ratification by American and British governments, which came in February 1815, the United States secured its existing boundaries because the war didn't cause geographical changes. According to historians interpretations, Native Americans were the big losers of the war. They were dreaming to create an Indian state as a British protectorate and as a consequence of the war, they had to abandon that dream at the same time that the resistance of native tribes in the western and southern borders was suppressed. Years later, President Andrew Jackson on May 28, 1830, signed into law the Indian Removal Act authorizing the president to grant unsettled lands west of the Mississippi in exchange for Indian original territory.
