The Kingdom of Travancore (/ˈtrævəŋkɔər/; [t̪iɾuʋit̪aːmkuːr])(Malayalam:തിരുവിതാംകൂർ) was an Indian kingdom until 1949. It was ruled by the Travancore Royal Family from Padmanabhapuram, and later Thiruvananthapuram. At its zenith, the kingdom covered most of modern-day central and southern Kerala, as well as Kanyakumari, Tamil Nadu. The official flag of the state was red with a dextrally-coiled silver conch shell (Turbinella pyrum) at its center. In the early 19th century, the kingdom became a princely state of the British Empire, and the king was accorded a 21 gun-salute locally and a 19-gun salute outside the kingdom. The Travancore Government took many progressive steps on the socio-economic front and during the reign of Maharajah Sri Chithira Thirunal Balarama Varma, Travancore became the second most prosperous princely state in British India, with reputed achievements in education, political administration, public work and social reforms.
