D. More land. more land equals more power.
In the 1840s, the U.S was struck with the idea of <em>manifest destiny</em>. An idea that America should control North America from the Atlantic Ocean to the Pacific Ocean. Mexico had the legal right to Texas thus dominated California, Arizona, and New Mexico. Two territories stood in America's way of accomplishing the manifest destiny idea; first, the Oregon Territory that was occupied by both Great Britain and the United States and the Western and Southwestern areas owned by Mexico. The differences between the United States and Mexico over the border of Texas led to the Mexican American War that resulted in American gaining ownership of Arizona, California, New Mexico, and Texas. The ownership of these territories fulfilled the '<em>Manifest Destiny' </em>of the U.S stretching from the Atlantic to the Pacific, Manifest Destiny.
<span>Most people at that time thought the world was flat. When you
sailed out to sea and they could no longer see your ship they assumed
you fell off the edge of the world. Columbus figured out (not by
himself, other educated people also knew this) that the world was round.
He figured it was a lot smaller though. He thought he could sail out
into the ocean and come out in India, there by taking a short cut and
putting one over on Spain. What Columbus didn't realize was the world
was alot bigger than he thought and there was a whole Continent out
there nobody knew about. Sooooo when he landed in S. America he thought
he was in India.</span>
It would be caravans i think
