In the early 2160s, Lydia Littlejohn was the President of United Earth, and was in office when the Articles of the Federation were signed, establishing the United Federation of Planets. (SCE eBook: The Future Begins, ST novel: Starfleet: Year One)
- The Tales of the Dominion War short story "Eleven Hours Out" also established a role of Prime Minister of United Earth, which is confirmed by the ENT novels The Good That Men Do and Beneath the Raptor's Wing. This would seem to indicate that United Earth is a parliamentary or semi-presidential republic, with the President as head of state and the Prime Minister as head of government.
