The first major wagon train to the northwest departs from Elm Grove. Missouri, on the Oregon Trail.
Although U.S. sovereignty over the Oregon Territory was not clearly established until 1846, American fur trappers and missionary groups had been living in the region for decades, to say nothing of the Native Americans who had settled the land centuries earlier. Dozens of books and lectures proclaimed Oregon’s agricultural potential, piquing the interest of white American farmers. The first overland immigrants to Oregon, intending primarily to farm, came in 1841 when a small band of 70 pioneers left Independence, Missouri. They followed a route blazed by fur traders, which took them west along the Platte River through the Rocky Mountains via the easy South Pass in Wyoming and then northwest to the Columbia River. In the years to come, pioneers came to call the route the Oregon Trail.
On this day in 1843, some 1,000 men, women, and children climbed aboard their wagons and steered their horses west out of the small town of Elm Grove, Missouri. The train comprised more than 100 wagons with a herd of 5,000 oxen and cattle trailing behind. Dr. Elijah White, a Presbyterian missionary who had made the trip the year before, served as guide.
