The Kingdom of Mysore was a geopolitical realm in southern India founded in around 1399 in the vicinity of the modern-day city of Mysore and prevailed until 1950. The territorial boundaries and the form of government transmuted substantially throughout the kingdom's lifetime. While originally a feudal vassal under the Vijayanagara Empire, it became a princely state in British India from 1799 to 1947, marked in-between by major political changes.
