Why did so many us settlers go to oregon in the late 1830s and early 1840s

The first wave of American movement into Oregon was very small.  This was a movement that was caused by the desire to participate in the fur trade.  By 1811, for example, the Pacific Fur Company had started to build Fort Astoria as a trading post at which it could obtain furs.  Americans who went to Oregon during this time were largely interested in participating in this trade.

In the late 1830s and early 1840s, many more Americans started to move to Oregon.  This was the era of the famous Oregon Trail.  These settlers were motivated by a desire for land, not by a desire for furs.  They were not going to Oregon to trade but rather to set up their own new homes.  They had heard that Oregon (in particular the Willamette Valley) was very fertile and had good weather.  They wanted to set up farms in that area, thus giving themselves the chance to become wealthier and more independent than they had been farther east.

Thus, the first (smaller) group of Americans came to Oregon for furs while the second (bigger) group came to settle on the lush farmland of region.
