What was a significant challenge for the Confederacy during the Civil War concerning state governance?

A significant challenge for the Confederacy during the Civil War was indeed the weak central government power. The Confederacy was established on a belief in states' rights, which meant that individual states retained a great deal of autonomy and authority. This political framework severely limited the central government's ability to enforce policies, coordinate military efforts, and mobilize resources effectively.

As the war progressed, the Confederacy faced difficulties in unifying its member states under a coherent national strategy. Each state prioritized its own interests and was reluctant to contribute resources or manpower to the central authority. This lack of central control hampered the Confederacy’s ability to wage war effectively, leading to problems such as inconsistent military decisions and a fragmented supply chain.

The other options highlight aspects that were either not significant challenges for the Confederacy or were contrary to their experience. For example, strong support for a federal constitution was not an issue for the Confederacy, as they explicitly sought to break away from federal authority. Similarly, the Confederacy did not have unified transportation systems, and their inconsistent taxation policies reflected the struggles of a weak central government rather than a challenge they successfully managed. Thus, the limitation of central authority was a central issue that plagued the Confederacy throughout the Civil War.
