Deep Space Nine is a Federation outpost on the edge of Cardassian space. The station belongs to the Bajorans, a race of spiritual people whose home planet Bajor was until recently occupied by the Cardassian. After many years of terrorist attacks by the Bajorans, the Cardassians withdrew from Bajor. The Bajoran Provisional Government has asked the Federation for help with the immense task of rebuilding Bajor after the occupation. A small Federation crew under the leadership of Commander Benjamin Sisko have established a presence on the space station.
