Udai Singh II

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 Mewar dynasty. He was the fourth son of Rana Sanga and Rani Karnavati, a princess of Bundi.
Early life, marriage, and parenthood.
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, Banbir 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 Banbir and took him to Kumbhalgarh. She started living in Bundi and did not allow Udai Singh to come and meet her. He lived secretly in Kumbhalgarh for two years, disguised as a nephew of the governor Asha Shah Depura (Maheshwari).
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 Akhey Raj Songara of Jalore), was born in the same year. He had 24 sons. His second wife, Sajjabai Solankini gave birth to his son Shakti Singh, Sagar Singh and Vikram Dev. Dheerbai Bhattiyani was his favourite wife and was the mother of his son Jagmal Singh. His fourth wife was Rani Veerbai Jhaala.
Reign.
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 Mewars 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 lake was completed in 1562 and the new capital soon came to be known as Udaipur.
In 1557, he was defeated by Maldev Rathore at the Battle of Harmada and lost Merta to him.
In 1562, Udai gave refuge to Baz Bahadur. the last ruler of the Malwa Sultanate, whose kingdom had been annexed into the Mughal Empire. 
In September 1567, his son Shakti Singh came to him from Dhaulpur and told him of Akbar's plan to capture Chittor. According to Kaviraj Shyamaldas, Udai Singh called a council of war. The nobles advised him to take refuge along with the princes in the hills, leaving a garrison at Chittor. On 23 October 1567 Akbar formed his camp near Chittor. Udai Singh retired to Gogunda (which later became his temporary capital) leaving Chittor in the hands of his loyal chieftains Rao Jaimal and Patta. Akbar captured Chittor after a four-month-long siege on 23 February 1568; the siege culminated in a brutal sacking of the city, leaving Chittor's garrison and 25-40,000 civilians dead. With Chittor lost to the Mughals, Udai would later shift his capital to Udaipur. 
He died in 1572 in Gogunda. Before his death, Jagmal tried to seize the throne but the nobles of Mewar prevented Jagmal from succeeding and placed Maharana Pratap Singh on the throne on 1 March 1572.
