Final answer:
Washington Territory was created by the federal government in 1850 as part of the larger issue of expanding slavery into newly acquired territories. The creation allowed the government to control and manage the settlement of the region and enforce the exclusion of slavery.
Step-by-step explanation:
The federal government created Washington Territory in 1850 because it was part of the larger issue of expanding slavery into newly acquired territories. The Northwest Ordinance of 1787 gave Congress greater control over the settlement of western territories, and statehood was granted based on certain population requirements.
It also specified that territories must forbid slavery and protect religious freedom. By creating Washington Territory, the federal government aimed to control and manage the region's settlement and ensure the exclusion of slavery. Furthermore, establishing Washington Territory provided a strategic advantage for the federal government in terms of defense and security. By extending its control over the region, the government could protect its interests and maintain stability in the western frontier.
