Explanation:
The Russo-American Treaty of 1824 established a clear border between American and Russian lands on the West Coast as well as trade. It gave Russian claims south of parallel 54°40′ north to the US.
Russia was inclined to give away this territory, which was in dispute between them, Britain, America and Spain, to insure their undisputed and ongoing ownership over Alaska. They were in no position to enforce their claims militarily and the trade value of territories other than Alaska was limited. They decided to get the best agreement that they could to avoid conflict.
A few years later, even Alaska became difficult for them to manage, and, once again fearing losing the land without compensation to either the US or Britain, they negotiated the Alaska purchase.

Brief explanation:
Increasing numbers of slaves were transported across the Atlantic because of the new form of farming that developed in the European colonies of the New World.
European farmers attempted to use native populations as a source of labour, which proved difficult. However, tha did not stop the development of the New Word.
With new land available, labourers were always tempted to leave their job and start their own farm. Wages needed to be high enough to tempt them to stay, reducing the planters’ profit margins.
The status of slaves as property was long established. The use of the property law meant that the enslaved were not considered humans, but commodities.
Several ideas from the time supported the enslavement of Africans:
Africans were seen as more suited to work on the plantations
African captives would be executed if the slave trade was abolished
African slaves were seen as benefitting from being looked after by the superior Europeans
Some Bible passages were used to justify slavery. In Genesis Noah placed the 'curse of Ham' on the descendents of his son, starting with his grandson Canaan.
The slaves have done their work. They have done their time, we are tired of working for those who are not helpless.
