Clan na Gael is an Irish-American organization founded in the late 19th century, primarily aimed at promoting Irish nationalism and supporting the struggle for Irish independence. The group has its roots in the Fenian Brotherhood, which sought to establish an independent Irish republic through various means, including political activism and fundraising. The organization has played a significant role in mobilizing support for Irish causes in the United States. Clan na Gael has been involved in various activities, such as organizing events, providing financial assistance to Irish nationalist groups, and fostering a sense of community among Irish-Americans, particularly during the Irish War of Independence.
