Who supported Irish nationalism?

Irish nationalism was supported by various groups and individuals, including political leaders like Daniel O'Connell and later figures such as Charles Stewart Parnell and Éamon de Valera. It garnered backing from cultural movements, particularly during the late 19th and early 20th centuries, with organizations like the Gaelic League promoting Irish language and heritage. Additionally, the Irish Republican Army (IRA) and other militant groups emerged to advocate for independence through more direct actions. Support also came from the Irish diaspora, particularly in the United States, which played a significant role in mobilizing resources and public opinion in favor of Irish nationalism.
