The Union League is a group of private clubs in the United States that were originally established to support the Union during the American Civil War. These clubs often focused on promoting civic responsibility, political engagement, and social welfare. They played a significant role in advocating for the rights of African Americans and supporting the Republican Party during the Reconstruction era. Today, the Union League continues to serve as a social and political hub, offering networking opportunities and events for its members. Each club typically features dining facilities, meeting rooms, and recreational amenities, fostering a sense of community among its members.
