Answer: Some historians believe that the Mississippi River's control was a key factor that decided the victor in the war.
Explanation:
Statistics say that as many as 26 battles were fought around that strategic place during the civil war and countless smaller conflicts. Control of the Mississippi River was one of the key factors in the Civil War. After the Union gained control of the Mississippi River, it gained a huge strategic advantage. In the first place, it divided the Confederation into two parts, and since the communication was flowing along that river, communication with the Confederation was disabled. With this move, the Union also economically weakened the Confederation since there was a huge flow of goods along the river to be disabled. Thus the Confederation was economically in disarray.
The line was important because it was established that any new western state that would be south of the line could be a slave state, while any new state in the west north of the line would be a slave free zone. This was done according to the Missouri compromise when slavery was an issue once more in 1850. The line also became the northern border of Texas when it was later added to the union.
