Shah Jahan and Mumtaz Mahal were married for 19 years. They had thirteen children together. Seven of the children died at birth or at a very young age. A Mughal prince could only become the Emperor if they fought well and became respected. Mumtaz travelled with Shah Jahan and his army as he carried out military campaigns. Mumtaz Mahal supported Shah Jahan and they respected each other very much. Mumtaz Mahal died on June 17, 1631 in Burhanpur in the Deccan (now in Madhya Pradesh) during the birth of their fourteenth child, a daughter named Gauhara Begum.
She had been with her husband as he was fighting a campaign in the Deccan Plateau. Her body was kept at Burhanpur in a walled pleasure garden known as Zainabad. A popular story says that on her deathbed, her last wish to the emperor was for a symbol or a monument to their love. She also asked her husband not to marry anyone else. The emperor promised immediately. Her body was buried in the Taj Mahal in Agra.
After she died, Shah Jahan went into mourning for a year. When he appeared again, his hair had turned white, his back was bent, and his face worn. Jahan's eldest daughter, Jahanara Begum, slowly brought him out of mourning and took the place of Mumtaz at court.
