The Federated Commonwealth was the union of the Lyran Commonwealth and Federated Suns. The accession of Archon-Prince Victor Steiner Davion in 3055 formally brought the nation into being. Katherine Steiner-Davion seceded the Lyran half of the nation in 3057, creating the Lyran Alliance. Victor abdicated the throne in 3067 and his successor, Prince-Regent Yvonne Steiner-Davion, renamed the rump Commonwealth "Federated Suns".
