She was the daughter of the Qajar Prince Zahir as-Sultan Vala and Afagh Khanom.

At four years old, her future mother-in-law, Princess Malekeh Jahan, arranged her marriage to Crown Prince Ahmad Mirza.

Badr al-Molouk was taken from school and married to Ahmad Mirza when she was twelve years old in 1909.

The wedding was held by the Crown Prince's mother, Malekeh Jahan, and was a great ceremony.

She did not play a public role during the reign of her spouse, since royal women at this time period still lived in seclusion.
