The Ainslie Tavern Bond (also known as the "Ainslie Band", or the "Ainslie Tavern Band") was a document signed on about 20 April 1567 by a number of Scottish bishops and nobles. The bond approved the Earl of Bothwell's acquittal on 12 April of implication in the murder of Lord Darnley, recommended him as an appropriate husband for Mary, Queen of Scots, and pledged to assist in defending such a marriage.[1][2]
