Did the confederacy declare war against the United States? Did the United States declear war on the confederacy.

As to the first question, the answer is yes, but it seems to have been largely a state by state decision.

- The Declaration of Causes of Seceding States.

- Maryland, My Maryland.

- Confederate States of America - Declaration of the Immediate Causes Which Induce and Justify the Secession of South Carolina from the Federal Union.

- Congress declares Civil War’s aims July 25, 1861.

- Message of Jefferson Davis to the Provisional Congress of the Confederate States of America.

- The Decision to Secede and Establish the Confederacy: A Selection of Primary Sources

 

As to the second, the answer is no, but Lincoln did issue, the following proclamation creating the militias thought necessary to fight the war. More would eventually be needed.

- Abraham Lincoln, Monday, April 15, 1861 (Proclamation on State Militia).
