Jaisalmer ka Kila was built by RajaRawal Jaisal in 1156 AD. He was a Bhatti Rajput ruler. He chose the Trikuta hills of the great Thar desert to symbolise the dominance, power and royalty of Rajputs. The Jaisalmer Fort has not only celebrated its impressiveness several times in history but also witnessed several battles with Khiljis, Tughalaqs, Mughals and Rathore Kings.
In 1276 AD, Rawal Jethsi built a defence system known as Rang Burj. He decided to use this Rang Burj after Alauddin Khilji, tried twice to invade the Jaisalmer Fort.
Sultan Alauddin Khilji's army surrounded Jaisalmer fort for eight to nine years and after reprised attempts, captured it in 1294 from Rajpur Bhattis. Due to this successful invasion, almost twenty-five thousand women did Jauhar or self-immolation to protect their integrity.
After two years, Khilji's army left the castle on its own. The surviving Bhattis regained the former glory of the fort. Another act of Jauhar took place in the late 14th century when Sultan of Delhi, Sultan Firoz Shah Tughlaq attacked Jaisalmer.
Further, another invasion by Mughal emperor Humayun in 1541 broke the defending system of King Rawal Lunakran. Due to this reason, he was forced to marry her daughter to Akbar.
Till 1762, Mughals ruled over Jaisalmer and was soon taken over by Maharawal Mulraj. He signed a treaty with the British East India Company. Thus, Jaisalmer soon became a princely state in Rajasthan. However, after the independence, Jaisalmer joined the Union of India and became a part of it.
