Oregon Treaty Definition: APUSH Study Guide

📚 Definition of the Oregon Treaty

The Oregon Treaty, signed in 1846, was a pivotal agreement between the United Kingdom and the United States that established the boundary between British North America (now Canada) and the United States. It resolved competing territorial claims over the Oregon Country, a vast region west of the Rocky Mountains.

📜 Historical Background

Prior to the treaty, the Oregon Country was jointly occupied by both British and American interests. This arrangement, established by the Treaty of 1818, allowed citizens of both nations to settle and trade in the region. However, as American migration westward increased, particularly along the Oregon Trail, pressure mounted to resolve the boundary dispute. The rallying cry of "Fifty-Four Forty or Fight!" reflected the expansionist sentiment in the United States, advocating for the U.S. to claim all territory up to the 54°40' north latitude, which was the southern boundary of Russian Alaska.

• 🧭 Joint Occupation:
• The Treaty of 1818 established joint occupation, allowing both British and American citizens to inhabit the Oregon Country.

🔑 Key Principles of the Treaty

The Oregon Treaty ultimately established the boundary along the 49th parallel, from the Rocky Mountains to the Strait of Georgia. Vancouver Island remained entirely under British control. Navigation rights were granted to the Hudson's Bay Company on the Columbia River. This compromise avoided potential conflict and set the stage for future relations between the two countries.
