Pennsylvania challenged Virginia’s claim to Pittsburgh by arresting Dr. John Connolly and removing him to Hannastown to stand trial. [Historic Pittsburgh]
From Len Barcousky for the Pittsburgh Post-Gazette (2007):
Squabbles between Virginia and Pennsylvania over which colony had jurisdiction over the region continued for more than 20 years. The dispute culminated in 1774 with a clash that saw rival militias and magistrates threatening and arresting each other.
British troops had abandoned Fort Pitt in 1772. Less than two years later, Lord Dunmore, who was Virginia’s Royal Governor, authorized a sometime-Fort Pitt resident, Dr. John Connolly, to raise a militia to take control of the frontier outpost. Dr. Connolly’s recruiting poster called for a public meeting on Jan. 25, 1774.
When Capt. Arthur St. Clair, Pennsylvania’s representative in the region, saw one of the posters, he arrested Dr. Connolly the day before the meeting. He had him jailed at Hannas Town, the county seat of the then much larger Westmoreland County. (read more)
