Kingdom of Marwar, also known as the Jodhpur State under the British, was a kingdom in the Marwar region from 1243 to 1818 and a princely state under British rule from 1818 to 1947. It was established in Pali by Rao Siha, possibly a migrant Gahadavala noble, in 1243. His successors continued to struggle against regional powers for domination and 9 out of 15 rulers till 1438 died in combat. In 1395, its capital was changed to Mandore by Rao Chunda of Mandore and to Jodhpur in 1459 by Rao Jodha.
