Question

1. what was the outcome of polks expansionist policies in the oregon territory?

the oregon territory was split between the united states and britain.
the united states and britain warred over rights to the oregon territory.
polk forced britain to surrender its land in the oregon territory.
mexico received part of the oregon territory.

Explanation:

Under Polk's expansionist policies, the Oregon Treaty of 1846 was signed. This treaty aimed to resolve the long - standing territorial dispute between the United States and Britain over the Oregon Territory. Instead of going to war (which was a possibility given the "54 - 40 or fight" slogan during the election, but more of a political stance), a diplomatic compromise was reached. The territory was divided at the 49th parallel. This division was a practical solution as both countries had settlers and economic interests in the region. It was not a case of one country forcing the other to surrender all claims (as in the option of Polk forcing Britain to surrender all land) or a war over rights that lasted indefinitely (the "warred over rights" option is incorrect as a treaty was eventually signed). Mexico had no claim to the Oregon Territory at this point (so the option about Mexico receiving part is wrong).

Answer:

The Oregon Territory was split between the United States and Britain.
