What role did Howell Cobb assume after Georgia's secession from the Union in 1861?

After Georgia's secession from the Union in 1861, Howell Cobb took on a significant leadership role as the President of the Provisional Confederate Congress. This position was pivotal during the early stages of the Confederacy, as it involved overseeing the assembly that was responsible for establishing the framework of the Confederate government and addressing critical issues pertaining to the Confederacy's formation and function.

Cobb's presidency in this context was marked by his efforts to organize the new government and promote unity among the seceding states. His influence was crucial as the Confederacy sought to establish itself amidst the civil turmoil. In contrast, the other roles listed—Governor of Georgia, Vice President of the Confederacy, and Congressman for Georgia—were not positions that Cobb held immediately after Georgia's secession. Instead, those roles pertained to different individuals or different periods in Cobb's political career. Thus, his role in the Provisional Confederate Congress is the most accurate and relevant position to highlight from that time.
