The United States federal government had left…

August 1848 CE

The United States federal government had left their part of the Oregon Country unorganized for two years until news of the Whitman massacre had reached the United States Congress and helped to facilitate the organization of the region into a U.S. territory.

On August 14, 1848, Congress passes the Act to Establish the Territorial Government of Oregon, which creates what is officially the Territory of Oregon.

The Territory of Oregon encompasses all of the present-day states of Idaho, Oregon and Washington, as well as those parts of present-day Montana and Wyoming west of the Continental Divide.

Its southern border is the 42nd parallel north (the boundary of the Adams-Onis Treaty of 1819), and it extends north to the 49th parallel.

Oregon City, Oregon, is designated as the first capital.
