The Capellan March is an administrative subdivision of the Federated Suns. Originally one of five Marches, the Capellan March grew with the disbandment of the Terran March. Also, the Sarna March was disbanded following Operation Guerrero and the subsequent Lyran secession from the Federated Commonwealth. Though most of the Sarna March was either gobbled up by the Capellan Confederation or became part of the Chaos March, the Achernar PDZ remained in Federated Suns' hands and was added to the Capellan March.
The Capellan March has traditionally been the land hold of House Hasek, whose leader also holds the title of Duke of New Syrtis, the capital world of the Capellan March. The Duke or Duchess of New Syrtis also holds hereditary title to the position of Minister of the Capellan March. Unless unqualified for some reason, or occupying a superior position, the head of the Hasek family is also the director of the Capellan March command (which carries the rank of Field Marshal). This effectively concentrates civilian and military authority for the border march in the hands of one individual, who can then use all the resources at his or her disposal to deal with any military threats. The people of the March have traditionally nurtured a deep hatred of the neighboring Capellan Confederation.
For military purposes, the march is divided into two Operations Areas or Combat Theaters, Edgeward and Coreward. Despite the fact that New Syrtis is located in the Edgeward Combat Theater, command is headquartered on Taygeta (giving it the alternate name of the Taygeta OA). The Coreward Combat Theater's HQ has traditionally been on Kathil, however Duke George Hasek moved it to Novaya Zemlya during the FedCom Civil War and seems content to leave it there (but it is still known as the Kathil OA). From there, the Theaters are broken down into over a dozen Polymorphous Defense Zones (PDZs).
