The national flag of Ireland is a tricolour of green, white and orange. The flag is twice as wide as it is high. The three colours are of equal size and the green goes next to the flagstaff.
The flag was first introduced by Thomas Francis Meagher in 1848 who based it on French tricolour.
The green represents the older Gaelic tradition while the orange represents the supporters of William of Orange. The white in the centre signifies a lasting truce between the 'Orange' and the 'Green'.
It was not until the Rising of 1916, when it was raised above the General Post Office in Dublin, that the tricolour came to be regarded as the national flag.
It is now enshrined in the Constitution of Ireland.
