** Isaac Barré, a member of the British House of Commons for Wycombe and a veteran of the French and Indian War in the British American colonies, coins the term "Sons of Liberty" in a rebuttal to Charles Townshend's derisive description of the American colonists during the introduction of the proposed Stamp Act. Barré notes that "They fled from your tyranny to a then uncultivated and unhospitable country... And yet, actuated by the principles of true English liberty, they met all these hardships with pleasure, compared with those they suffered in their own country, from the hands of those who should have been their friends." American colonists adopt the term for their own organization after reading the accounts of Barré's speech.

I had not walked further than the Golf-house when the whole thing was arranged in my mind."
* June 21 – The Isle of Man is brought under British control, the Isle of Man Purchase Act (coming into force 10 May) confirming HM Treasury's purchase of the feudal rights of the Dukes of Atholl, as Lord of Mann over the island, and revesting them into the British Crown.
