Evolution of the Irish flag

The green harp flag
A green field bearing a gold harp, widely used from the 17th century onward as a national symbol of Ireland and associated with various nationalist movements prior to the adoption of the tricolor.
History of Ireland’s flag
The harp has been associated with Ireland since at least the medieval period and appears in manuscripts and heraldic rolls from the 13th century. By the 17th century, a green flag bearing a gold harp was in use and became widely regarded as a national symbol of Ireland.
In 1642, a green harp flag is recorded as being used by forces led by Eoghan Ruadh Ó Néill. During the 18th century, green became increasingly associated with Irish nationalist movements. The United Irishmen in the 1790s used green flags, often featuring a harp emblem.
Emergence of the tricolor
The earliest recorded use of the colors green, white and orange together as a political emblem dates to 1830, when tricolor cockades were worn at public meetings.
The modern Irish tricolor was first publicly unveiled on 7 March 1848 in Waterford by Thomas Francis Meagher. Inspired by the French tricolor, the design symbolized hoped-for unity between traditions represented by green and orange, with white representing peace between them.
The flag did not gain widespread acceptance at the time and was rarely used between 1848 and the early 20th century. The green harp flag remained more common during this period.
Adoption during the independence period
The tricolor gained prominence during the Easter Rising of 1916 when it was raised above the General Post Office in Dublin. From that point, it became closely associated with the Irish independence movement.
During the Irish War of Independence (1919–1921), the tricolor was used as the flag of the proclaimed Irish Republic.
After the establishment of the Irish Free State in 1922, the new government continued to use the tricolor, although this was not initially specified in legislation.
Constitutional confirmation
In 1937, the Constitution of Ireland formally confirmed the national flag in Article 7, stating: “The national flag is the tricolor of green, white and orange.”
The design has remained unchanged since.
