USA HISTORY

Detailed explanation-1: -The Oregon Trail has attracted such interest because it is the central feature of one of the largest mass migrations of people in American history. Between 1840 and 1860, from 300, 000 to 400, 000 travelers used the 2, 000-mile overland route to reach Willamette Valley, Puget Sound, Utah, and California destinations.

Detailed explanation-2: -In 1841, the Bartleson-Bidwell Party was the first emigrant group credited with using the Oregon Trail to emigrate west. The group set out for California, but about half the party left the original group at Soda Springs, Idaho, and proceeded to the Willamette Valley in Oregon, leaving their wagons at Fort Hall.

Detailed explanation-3: -The first overland immigrants to Oregon, intending primarily to farm, came in 1841 when a small band of 70 pioneers left Independence, Missouri.

Detailed explanation-4: -Webster and Ashburton avoided issue while arriving at their treaty in 1842, feeling that other issues were more pressing. About that time “Oregon fever” set in, a result of the panic of 1837 and the attractiveness of rich farmland that could be cultivated year-round.
