Antique Orange Institute Soft Paste Mug

The Orange Institution is a fraternal order based in Northern Ireland.  Founded in 1795 its name is a tribute to the Dutch-born Protestant king William of Orange, who defeated the Catholic English king James II in the Williamite–Jacobite War (1689–1691).   It is primarily associated with Ulster Protestants, with lodges in England, Scotland, Wales, Republic of Ireland, as well as the United States. 

Along the bottom  of the front of the mug reads: "May the Orange Institution stand as firm as the oak and the enemies fall off like the leaves in October".
