C. The Oregon Country
The Oregon Country was acquired in June 1846, at a time of James K. Polk's term, a president characterized for his advocacy for American westward expansion
The United States' occupation of Oregon Country started in 1818 by Britain's consent. And by the 1840s, Americans outnumbered British people. In 1845, the United States tried to negotiate the division of the Oregon territory, and a year later in June, both nations finally agreed to divide the territory at the 49th parallel.
"Oregon Country" is now the American's states of Oregon, Washington, and Idaho, as well as portions of Montana and Wyoming.
