Early Settlers 1835–1862

The first phase of white migration into the West was about crossing it, not settling on it. Between 1835 and 1862 the Plains were seen by most migrants as a dangerous obstacle between the settled United States and something better — good farmland in Oregon, gold in California, religious freedom in Utah. This lesson traces those early migrations: the Oregon Trail, the Mormon exodus to Salt Lake, and the California Gold Rush. It also sets up the first sustained US government engagement with the Plains — the beginning of the reservation system — and explains why each of these seemingly separate stories mattered for Plains Indian society.

The Oregon Trail

By the early 1840s word had spread in the eastern United States that the Willamette Valley in Oregon Territory offered abundant, well-watered farmland. Land in the east was becoming expensive and often exhausted after decades of tobacco and cotton farming. Economic depressions in the 1830s pushed families to look west. Missionary letters and newspaper articles built up Oregon's reputation as a Promised Land.

The Oregon Trail ran for about 2,000 miles from Independence, Missouri to the Willamette Valley. The first large wagon train — about 1,000 settlers — set out in 1843, in what became known as the "Great Migration". The Trail was then used by around 400,000 people between 1843 and the coming of the railroad in 1869.

Stage	Distance	Main hazards
Independence to Fort Kearny	~300 miles	River crossings, thunderstorms
Fort Kearny to Fort Laramie	~300 miles	Grassland, limited water
Fort Laramie to South Pass	~400 miles	Ascending Rockies; altitude sickness
South Pass to Fort Hall	~300 miles	Desert stretches
Fort Hall to Oregon	~700 miles	Mountains; exhaustion; food shortage

Daily life on the Trail was gruelling. Families walked most of the way — wagons were for goods, not passengers. A train averaged 15 miles a day. Disease, particularly cholera, was the biggest killer, spread through contaminated river crossings. Historians estimate around one grave per 200 metres of the main route.

Mini-example: a Q1 consequence

Explain two consequences of the opening of the Oregon Trail.

• Consequence 1 — Disruption of Plains Indian hunting. Wagon trains killed grass, frightened buffalo and polluted water along a narrow corridor through Pawnee and Lakota lands. This pushed the buffalo herds further from regular hunting grounds, weakening Plains nations dependent on them.
• Consequence 2 — Pressure for US government forts. To protect migrants from both weather and perceived Indian threats, the army built or expanded forts such as Kearny and Laramie in the 1840s — establishing permanent US military presence on the Plains for the first time.

Each consequence names the change and explains the mechanism. That is what Q1 Level 3 wants.

Mormon Migration

The Mormons — properly, the Church of Jesus Christ of Latter-day Saints — were founded by Joseph Smith in upstate New York in 1830. Their beliefs — a new scripture (the Book of Mormon), a prophetic leader, and, from 1843, the practice of polygamy — brought intense hostility from neighbours wherever they settled. Driven from New York, Ohio, Missouri and finally Illinois, they faced mob violence culminating in Smith's lynching in 1844.

Leadership passed to Brigham Young, a gifted organiser who concluded that Mormon survival required isolation in territory no one else wanted. He chose the Great Salt Lake basin in what was then Mexican territory — harsh, alkaline, treeless, and, crucially, outside the reach of US mobs. In 1846–47 Young led roughly 16,000 Mormons across the Plains to Salt Lake, founding the settlement in July 1847.

Mormon migration is distinctive for three reasons:

• Planned and communal. Unlike Oregon Trail families, Mormons moved as an organised people, with surveyed routes, supply depots, and centralised leadership.
• Engineering the desert. Mormon irrigation, which diverted mountain streams across the basin, turned the Salt Lake valley into one of the few successful large-scale agricultural colonies in the West before 1862.
• A model for later settlement. Mormon success showed that determined communities could live on the margins of the West — undermining the "Great American Desert" myth.

Arrival at Salt Lake	July 1847
Utah becomes US territory	1850

The California Gold Rush 1849

In January 1848 James Marshall found gold at Sutter's Mill on the American River in California. News spread slowly at first, then exploded through eastern newspapers in late 1848. By 1849 the "Forty-Niners" were pouring west — around 80,000 in that year alone, some overland, some by ship around Cape Horn or across the Panama isthmus.

The Gold Rush's consequences for this course are large:
