The President of the Republic of Haven was the head of state and head of government of the Republic of Haven.
With the implementation of the DuQuesne Plan, the office was replaced by that of the Hereditary President of the People's Republic of Haven, which was itself later replaced by that of the Chairman of the Committee of Public Safety. (HH3)
After the Committee was abolished with the death of its last chairman, Oscar Saint-Just, power was transfered to a provisional government, led by Aprilist Eloise Pritchart, until a new President could be elected. (HH9) Some time later, Pritchart became the first elected head of state of Haven in generations, and began to transfer the republic back to the state which its founders had intended. (HH10)
