What knowledge and provisions were needed by travelers headed west

The Oregon Trail was a roughly 2,000-mile route from Independence, Missouri, to Oregon City, Oregon, which was used by hundreds of thousands of American pioneers in the mid-1800s to emigrate west. The trail was arduous and snaked through Missouri and present-day Kansas, Nebraska, Wyoming, Idaho and finally into Oregon. Without the Oregon Trail and the passing of the Oregon Donation Land Act in 1850, which encouraged settlement in the Oregon Territory, American pioneers would have been slower to settle the American West in the 19th century.

Missionaries Blaze the Oregon Trail

By the 1840s, the Manifest Destiny had Americans in the East eager to expand their horizons. While Lewis and Clark had made their way west from 1804 to 1806, merchants, traders and trappers were also among the first people to forge a path across the Continental Divide.

But it was missionaries who really blazed the Oregon Trail. Merchant Nathan Wyeth led the first missionary group west in 1834 where they built an outpost in present-day Idaho.

Marcus Whitman

Determined to spread Christianity to American Indians on the frontier, doctor and Protestant missionary Marcus Whitman set out on horseback from the Northeast in 1835 to prove that the westward trail to Oregon could be traversed safely and further than ever before.
