Short answers, pulled from the story.
Humayun's son Akbar was born on the 15th of October 1542 within the courtyard of Umarkot Fort. This event occurred while Humayun was a fugitive seeking refuge from Sher Shah Suri in the territory of Rana Prasad Singh Sodha.
Rana Amar Singh originally constructed Umarkot Fort in the 11th century. The structure was later modified in 1746 by the Mughal Subahdar Noor Mohammad Kalhoro who added a new fort at the location.
Umar Marvi is a figure of resistance who was imprisoned in Umarkot Fort for many years after refusing to become the wife of Umar, the ruler of the region. Her steadfastness in the face of imprisonment turned her into an ideal for the local people and a symbol of moral integrity.
The Sodha Rajput dynasty held sway over Umarkot Fort for centuries and established a lineage of rulers known as the Ranas. Rana Megraj once held the governorship of the fort and maintained order and tradition long before the Mughal arrival.
After the formation of Pakistan in 1947, the fort came under the control of the Pakistani Government while the Sodha family retained their jagir located 16 kilometers away from the historic site. The British had previously taken over the area but the cultural imprint of the Sodha Rajputs remained deeply embedded in the local identity.
