The land included in the northwest territories was ceded to the united states following
a) the defeat of spanish colonies in the region.
b) great britain's defeat in the american revolution.
c) the indian removal that occurred after the french and indian war.
d) the withdrawal of the french colonists following the french revolution.

The correct answer is B) Great Britain's defeat in the American Revolution.

The land included in the Northwest Territories was ceded to the United States following Great Britain's defeat in the American Revolution.

We are talking about the Treaty of Paris of 1783, the agreement between the American colonies and Great Britain to officially end the Revolutionary War. By signing the treaty, Great Britain recognized the Independence of the 13 American colonies. It also clearly defined the Northwest territory for the US. The new territories included Illinois, Minnesota, Indiana, Wisconsin, and Ohio. Authorized the navigation of the Mississippi River. And authorized American ships to fish in the Grand Banks.

regarding the law, the 15th amendment was specifically designed thinking in the rights of black free men.

even though ratified on february 3, 1870, the promise of the 15th amendment would not be fully applied for a long time.poll taxes and literacy tests would allow southern states disenfranchise african americans. only in 1965 the voting rights for african americans would be actually able to vote in the south.

in 1965, president johnson signed the voting rights act, which aimed to overcome legal barriers that prevented african americans from voting as it was guaranteed by the 15th amendment to the u.s. constitution.

the american civil war was not caused   by slavery but by economic factors.
