Goa is a state on the south-western coast of India within the region known as the Konkan, separated from the Deccan highlands of the state of Karnataka by the Western Ghats. It is bounded by Maharashtra to the north and Karnataka to the east and south, with the Arabian Sea forming its western coast. It is India's smallest state by area and the fourth-smallest by population. Goa has the highest GDP per capita among all Indian states, two and a half times that of the country. It was ranked the best-placed state by the Eleventh Finance Commission for its infrastructure and ranked on top for the best quality of life in India by the National Commission on Population based on the 12 Indicators. Panaji is the state's capital, while Vasco da Gama is its largest city. The historic city of Margao still exhibits the cultural influence of the Portuguese, who first landed in the early 16th century as merchants and conquered it soon thereafter. Goa is a former Portuguese province; the Portuguese overseas territory of Portuguese India existed for about 450 years until it was annexed by India in 1961.
