Udai Singh II (4 August 1522 – 28 February 1572) was the Maharana of Mewar and the founder of the city of Udaipur in the present-day Rajasthan state of India. He was the 12th ruler of the Kingdom of Mewar. He was the fourth son of Rana Sanga and Rani Karnavati, a princess of Bundi. Early life Udai Singh was born in Chittor in August 1522. After the death of his father, Rana Sanga, Ratan Singh II was crowned King. Ratan Singh II was assassinated in 1531. He was succeeded by his brother Maharana Vikramaditya Singh. During the reign of Vikramaditya, when the Muzaffarid Sultan of Gujarat Bahadur Shah sacked Chittor in 1535, Udai Singh was sent to Bundi for safety. In 1537, Banvir killed Vikramaditya and usurped the throne. He tried to kill Udai Singh as well, but Udai's nurse Panna Dai sacrificed her own son Chandan to save him from his uncle Banvir and took him to Kumbhalgarh. He lived secretly in Kumbhalgarh for two years, disguised as a nephew of the governor Asha Shah Depura (Maheshwari Majahan). Personal life Udai Singh had 24 sons. His second wife, Sajjabai Solankini gave birth to his sons, Shakti Singh, and Vikram Dev Singh. Dheerbai Bhattiyani was his favourite wife and was the mother of his sons, Jagmal Singh, Kunwar Agar Singh, Kunwar Pachyad Singh. Dheerbai also bore Uday Singh two daughters. Rani Veerbai Jhaala was the mother of Kunwar Sagar Singh and Kunwar Rai Singh. Reign In 1540, he was crowned in Kumbhalgarh by the nobles of Mewar. His eldest son Maharana Pratap from his first wife, Maharani Jaivantabai Songara (daughter of Akheiraj Songara of Jalore), was born in the same year. In 1544 Sher Shah Suri invaded Marwar after defeating Maldev at Sammel. Udai Singh had just dealt with the civil war in Mewar and did not have the resources to fight the Sur Empire, he thus surrendered Chittor to Sher Shah Suri on the terms that Sher Shah does not harm the people of Mewar. Sher Shah also accepted the terms as he knew that the siege would be long and costly. Udai Singh and his council felt that Chittor was too vulnerable and thus planned to shift Mewar's capital to a safer location. In 1559 work started in the Girwa portion of Mewar and in the same year a man-made lake was made to promote cultivation. The
