The Hearts of Oak, also known as Oakboys and Greenboys, was a protest movement of farmers and weavers that arose in County Armagh, Ireland in 1761. Their grievances were the paying of the ever-increasing county cess, tithes, and small dues. The Hearts of Oak name came from the wearing of a piece of oak in their hats.[1] By the end of the protests the movement had spread to the neighbouring counties of Cavan, Fermanagh, Londonderry, Monaghan, and Tyrone.[1][2][3]
