Born as a Rathore princess of Mandore, she brought peace between her clan and that of her husband, the Sisodias, which lasted until the reign of her grandson, Rana Kumbha.

She advised her son during the beginning of his reign, questioned the intentions of Mewari nobles, and is also believed to have educated Rana Kumbha.

Rani Hansa Bai obtained help from her brother Ranmal to administer the state of affairs on behalf of Mokal until he became older.

However, there was resentment among the nobles of Mewar at the growing Rathore influence at court, in particular regarding the level of nepotism with which Ranmal awarded high positions.

Seeing an opportunity, Ranmal marched on the capital city, Mandore, at the head of a Mewari army and seized the throne, becoming the new Rao of Marwar.

In 1433, Mokal was assassinated by his paternal uncles, Chacha and Mera, which brought an end to the great Maharana in the making at the young age of 24.

Lack of support, however, caused Chacha and Mera to flee thus once more leaving a small child as ruler of Mewar, now in the person of Mokal's son Kumbha.

Hansa Bai, now the queen-grandmother again called on her brother Ranmal to take charge of the state and become regent until the new Rana reached an older age.

Ranmal accompanied by some of his twenty-four sons, returned to Chittor, nominally taking up the position of caretaker to his minor great-nephew though, for all intents and purposes, he became the true power in the kingdom.

[4] The new regent's first action was to strike the allies of Mewar's rival kingdoms of Gujarat and Malwa, the latter of which having sheltered Mokal's killers.

The rulers of Bundi, Abu, Bhoola and Basantgarh were crushed and the Sultan of Malwa, Mahmud Khalji, was defeated in the Battle of Sarangpur in 1437.

During this time Ranmal's son Jodha escaped from Mewar and it is possible that Hansa helped him, not wanting her homeland of Mandore to be without a king.
