The history of Travancore Government (Thiruvidankodu in Tamil) is well connected with the district of Kanyakumari. From 1729 to1949, for 220 years Travancore was ruled by 12 kings. Most of the events like internal wars of Travancore Government, the victory of Travancore Kings in the Colachel War, Upper garment agitation, establishment of postal department, construction of dams, palaces and administrative reforms took place in Kanyakumari. To highlight the 220 years of history, the 'Travangore Gallery' was organised in the Government Museum, Kanyakumari. It was declared open by His Highness Sri Uthiradam Thirunal (the Maharaja of Erstwhile Travancorestate) on 17.09.2003.
