For thousands of years before U.S. statehood, the land now called Oregon was home to many Indigenous peoples, including but not limited to the Chinook, Clatsop, Tillamook, Kalapuya, Molalla, Klamath, Modoc, Umatilla, Cayuse, Walla Walla, Paiute, Coos, Coquille, and Takelma. These communities developed sophisticated trade networks, food systems, fisheries, governance traditions, and cultural landscapes tied to rivers, prairies, forests, and the Pacific coast.
European and American maritime contact increased in the late 18th century. Spanish, British, and later American explorers and traders visited the coast, while the Columbia River became central to fur trading. The Lewis and Clark Expedition wintered near present-day Astoria in 1805-1806, helping place the region more firmly into U.S. public imagination. Astoria, founded in 1811 by the Pacific Fur Company, is often cited as the first permanent U.S. settlement on the Pacific coast.
During the early 19th century, Oregon Country was jointly occupied by the United States and Britain. The Hudson's Bay Company played a major role in the regional economy from Fort Vancouver, just north of the modern Oregon border. In the 1840s, large numbers of overland migrants arrived via the Oregon Trail, especially into the fertile Willamette Valley. The Provisional Government of Oregon was organized in 1843, and the Oregon Territory was created by Congress in 1848.
Statehood came on February 14, 1859. This period also included violent dispossession of Indigenous peoples, treaty-making under coercive conditions, warfare, disease, forced removal, and confinement to reservations. The state constitution originally included exclusionary provisions against Black settlement, reflecting a deeply discriminatory history that is now more openly studied and acknowledged.
In the late 19th and early 20th centuries, Oregon's economy expanded through timber, fishing, agriculture, railroads, and port activity. Portland became the state's main commercial city. Immigration from Europe and Asia, especially Chinese immigrants who contributed significantly to labor and commerce, shaped the state's development, though many communities faced exclusion, violence, and discriminatory laws.
The 20th century brought hydroelectric development on the Columbia River, expansion of higher education, modernization of transportation, and wartime industrial growth, especially during World War II. Postwar Oregon saw suburbanization, growth in electronics and manufacturing, and stronger environmental and land-use policies. In recent decades, the state has experienced population growth, housing pressures, wildfire risk, and political debates over urban-rural priorities, while continuing to build an identity around outdoor life, environmental stewardship, and innovation.
