East in Mississippi River and West in Rocky Mountains
The Mississippi River marked the eastern boundary of the Louisiana Purchase, while the Rocky Mountains served as the western boundary.
The Mississippi River and the Rocky Mountains.
The east was bounded by the Mississippi and the West ( andSouth) by the Missouri River.
The eastern border of the United States was still the Atlantic Ocean, but after the Louisiana Purchase in 1803, the western border wasn't well defined. We bought the place from France, and even the French weren't entirely sure what they were selling, or what we were buying. Nominally, the Louisiana Purchase included all of the land drained by the Mississippi River, so the western border should have been the Rocky Mountains and the Continental Divide.
The Louisiana Purchase. Also the Louisiana purchase was purchased by Americans So they could control the Mississippi River for trade because it was a HUGE thing back then. Added by tdog638
Louisiana purchase stretched from the Mississippi river to the rocky mountains.
eastern is the Mississippi river and the west is the rocky mountains
You have a misunderstanding here. Louisiana purchased nothing, the US purchased the territory that France identified as Louisiana which was much larger than the modern state of Louisiana. French Louisiana included all lands west of the Mississippi river except the southwest (claimed by Spain) and the Pacific northwest (claimed by England and Russia). However the precise boundaries of the Louisiana Purchase were (and still are) uncertain.
