Flag of Ireland
Ireland is an island nation in northwestern Europe known for its lush green landscapes, rich literary heritage from writers like Oscar Wilde and James Joyce, and vibrant Celtic culture. The island is divided between the Republic of Ireland and Northern Ireland, which is part of the United Kingdom. Ireland joined the European Economic Community in 1973 and has since become one of Europe's most prosperous economies, home to the European headquarters of many global technology companies.

What the flag of Ireland means
Green represents the Gaelic and Catholic tradition, orange the Protestant supporters of William of Orange, and the white between them a lasting peace between the two. The tricolour was presented by Thomas Francis Meagher in 1848, inspired by the flags of revolutionary France, and was widely flown after the 1916 Easter Rising. The 1937 constitution confirmed it as the national flag.
How to recognise it

Flag history of Ireland
Every flag that has flown over Ireland, from today back through time.
1922–present
Green-white-orange tricolour
First flown by Thomas Francis Meagher in 1848 and raised over the GPO during the 1916 Rising, the tricolour was used by the Irish Free State from 1922 and given constitutional status in 1937. Green represents Catholics, orange Protestants, and the white the hoped-for peace between them.
1642–1916
Green flag with gold harp
A green field bearing a golden harp was recognized as the flag of Ireland from the mid-1600s and remained the dominant nationalist emblem right up to the 1916 Easter Rising. The same design survives today as the flag of Leinster.
Saint Patrick's Saltire:
1783–present
St Patrick's Saltire
A red X-shaped cross on white, adopted by the Order of Saint Patrick in 1783 and folded into the Union Flag in 1801. Its status as a genuinely Irish symbol is disputed — it was largely an Anglo-Irish heraldic device.
