Answer:
One way in which the Confederate States of America (CSA) was similar to the United States was that both were federations of states. The CSA was a federation of 11 Southern states that had seceded from the United States and formed their own country. Like the United States, the CSA had a federal government that was responsible for certain national functions, such as foreign relations and defense, while the individual states retained certain powers and autonomy. Both the United States and the CSA were also based on the principles of federalism, which is a system of government in which power is shared between a central authority and the constituent states.
