In the Lois McMaster Bujold series about the Vorkosigan family, Komarr is a planet which isn't too far a trip from the Vorkosigan native planet of Barrayar, and for the past few decades ruled by Barrayar. It was conquered to make Barrayarans feel safe again after the Komarrans chose to let Cetagandan invaders through the wormhole between the two planets, so that Cetagandans could attack Barrayar. The Komarrans are only gradually adapting to Barrayaran government.
