Lunkaran was the third Rao of Bikaner, ruling from 1505 to 1526. He spent much of his two-decade long reign consolidating and expanding the territories of his relatively new kingdom.
In January 1505, Lunkaran ascended the throne at the age of 35 following the premature death of his elder brother Nara. His first military engagement was the suppression of nobles who, after having lost lands under Bika, had revolted during the reign of Nara. Later, in 1509, he marched against Man Singh Chauhan of Dardrewa, defeating him after a siege of seven months and absorbing his lands. In 1512, he invaded Fatehpur, which was being ruled by the Kayam Khani king Daulat Khan. Taking advantage of a feud between Khan and another ruler, Lunkaran swept into the region and annexed 120 villages. The following year, he defeated the Khanzada ruler of Nagaur in battle and also conquered extensive territory from Chayal Rajputs near Hisar and Sirsa. In early 1526, he became involved in a dispute with Rawal Jait Singh of Jaisalmer. Allegedly, the contention arose when Jait Singh insulted Lunkaran's clan, the Rathores, publicly in court. When chided by a noble visiting from Bikaner, the Rawal mocked them further by stating that he would bestow to the Brahmins of his kingdom as much land as the Rathors could ride over. When the noble reported the exchanged to Lunkaran, he took up the challenge and, with his riders, invaded the Rawal's territory. His forces penetrated as far as the city of Jaisalmer itself and laid siege to it, capturing Jait Singh in the process. He only lifted the assault and released the captive king after the latter pledged to give his daughter in marriage to one of Lunkaran's sons.
Death
In March that same year, Lunkaran and three of his sons rode into battle against the Nawab of Narnaul. However, while fighting in the village of Dhosi, several of his supporters withdrew from the battle. As a result of this, the Bikaner forces were overwhelmed, with Lunkaran and his sons being killed. He was succeeded on the throne by his son Jait Singh.
