Formerly the capital of the princely state of Bikaner, the city was founded by Rao Bika in 1486 and from its small origins it has developed into the fourth largest city in Rajasthan. Rao Bika was the first son of Maharaja Rao Jodha of the Rathor clan, the founder of Jodhpur and conquered the largely arid country in the north of Rajasthan. As the first son of Jodha he wanted to have his own kingdom, not inheriting Jodhpur from his father or the title of Maharaja. He, therefore, decided to build his own kingdom in what is now called Bikaner. The Ganges Canal, completed in 1928, and the Indira Gandhi Canal, completed in 1987, facilitated its development.
