Step-by-step explanation:
The Gaelic League was founded in 1893 by Douglas Hyde, Eoin MacNeill, and other Irish patriots. Its formation was part of a broader Celtic Revival, aiming to promote the Irish language and culture. The league played a significant role in the revival of Irish as a spoken language and in fostering Irish identity. Although not explicitly a political organization, it created an environment that contributed to the rise of Irish nationalism and organizations like Sinn Féin and the Irish Republican Army (IRA), which sought Ireland's independence from British rule.
