Answer 1

The eastern basin of the Mississippi River was obtained by Britain by treaty with France after victory in war. Specifically, this occurred as a result of the Treaty of Paris in 1763, which ended the French and Indian War (also known as the Seven Years' War). Under this treaty, France ceded its territories east of the Mississippi River to Britain, significantly expanding British control in North America.
