Oregon at a glance
Oregon was admitted to the Union on 1859, making it the 33rd state. It joined the country 83 years after the Declaration of Independence. Its capital Salem has been the seat of state government for most of the state's history.
Native peoples
For thousands of years before European contact, Indigenous peoples lived across what is now Oregon. Multiple distinct cultures developed in response to the region's geography — coastal peoples, plains peoples, river-valley peoples, mountain peoples — each with their own languages, governance, and trade networks. European colonization disrupted these civilizations dramatically, often through disease, displacement, and forced removal. Today, Oregon's Native heritage is preserved in place names, tribal nations within state borders, and ongoing cultural practices.
Path to statehood
The path from European exploration to statehood typically took decades. Oregon was admitted to the Union on 1859, after meeting the requirements set by Congress: sufficient population, a written constitution, and the consent of Congress. The process from initial settlement to statehood was the 73rd time the US expanded.
The modern era
Today Oregon has a population of 1 to 5 million and is one of the largest states in the country. The capital is Salem; the largest city is Portland. Agriculture remains an important sector of the state economy. The political lean has shifted over time and now leans reliably Democratic.
