Sir Frederick Haldimand, KB was a Swiss military officer best known for his service in the British Army in North America during the Seven Years' War and the American Revolutionary War. From 1778 to 1786, he served as Governor of the Province of Quebec, during which time he oversaw military operations against the northern frontiers in the war, and engaged in ultimately fruitless negotiations to establish the independent Vermont Republic as a new British province. His administration of Quebec was at times harsh, with the detention of numerous political dissidents and agitators.

The Vermont Republic, officially known at the time as the State of Vermont, was an independent state in New England that existed from January 15, 1777, to March 4, 1791. The state was founded in January 1777, when delegates from 28 towns met and declared independence from the jurisdictions and land claims of the British colonies of Quebec, New Hampshire, and New York. The republic remained in existence for the next fourteen years, albeit without diplomatic recognition from any foreign power. On March 4, 1791, it was admitted into the United States as the State of Vermont, with the constitution and laws of the independent state continuing in effect after admission.
