Ireland

Ireland's national flag is a green-white-orange vertical tricolour in a 1:2 proportion, with green nearest the hoist. The green represents the Gaelic and Catholic tradition, the orange represents the Protestant community associated with William of Orange, and the white symbolizes the hope for lasting peace and unity between them. The design was first unveiled in Waterford in 1848 by Thomas Francis Meagher of the Young Ireland movement, gained wide recognition after it was raised over the General Post Office during the 1916 Easter Rising, and was later adopted by the Irish Free State and recognized in the 1937 Constitution.
