Powers
The President of the Confederacy held most of the same powers as the US President. Though he could not directly propose legislation, he was given the power to nominate members of the Supreme Court, ambassadors, cabinet members, and other executive officals to be approved by the Senate.
He was also Commander-in-Chief of the Confederate Army and held veto power over legislation he does not like.
The President could be impeached by Congress for "treason, bribery, or other high crimes and misdemeanors."
Differences
There were a few key differences between the proposed Confederate President and the United States one:
Unlike the US, which allowed for indefinite re-election of both the President and VP after a four-year term, the Confederacy limited both offices to only one, six-year term. After the war, this innovation gained considerable popularity in the re-constituted Union, most notably being endorsed by Rutherford B. Hayes in his inaugural address.
The Confederacy did not indicate who succeeds to the office of President following the removal or death of both the President and Vice President. The constitution states that Congress will appoint an officer to act as President in such cases. In the US, the Presidency is passed to the Speaker of the House of Representatives then a long list of other offices.
Instead of a "State of the Union" speech the President of the Confederacy was to give a "State of the Confederacy" speech to a joint session of Congress once a year.
The President of the ConfederateStates was the Head of State of the short-lived republic of the ConfederateStates of America, which seceded from the United States.
According to the ConfederateStates Constitution, the president's office was almost entirely the same as that of the President of the United States.
Though he could not directly propose legislation, he was given the power to nominate members of the Supreme Court of the ConfederateStates, ambassadors, cabinet members, and other executive officials to be approved by the Senate.
The capital of the ConfederateStates of America was Montgomery, Alabama from February 4, 1861 until May 29, 1861.
The Confederate Congress responded to the hostilities by formally declaring war on the United States in May 1861--calling it "The War between the ConfederateStates of America and the United States of America." The Union government never declared war but conducted its war efforts under a proclamation of blockade and rebellion by President Lincoln.
The legislative branch of the ConfederateStates of America was the Confederate Congress.
