Mirza Jahagir's father, the Mughal Emperor Akbar Shah II (r. 1808–1837) was not happy with his eldest son Siraj Uddin “Zafar” (Bahadur Shah Zafar II) and wanted to nominate his younger son Mirza Jahangir as the heir apparent (Wali-Ahad). This move was not liked by Archibald Seton, then British Resident in the Red Fort. One day, when the British Resident at the court went to meet Akbar II, the topic of succession came up again, but the Resident stated the East India Company’s known position very firmly. Angry at this, Mirza Jahangir fired at the British Resident just as he was leaving the Red Fort, but missed.The Resident turned his horse back and asked the prince to apologise, but he refused and taunted him instead, by shouting “Lu, lu hai bey” (cranky booby fie on you). The Resident then went back and returned with a whole posse of British troops, bent on avenging the insult. The prince was arrested and sent in exile to Allahabad in about the year 1812.[3]
His mother pined for him and vowed that if he were to return, she would offer a chadar (canopy) of flowers at the dargah (shrine) of Khwaja Bakhtiar ‘Kaki’ at Mehrauli. After a couple of years, Mirza Jahangir was released, and Mumtaz Mahal Begum went to Mehrauli to redeem her vow. With her, the imperial court also shifted to Mehrauli and so did the entire population of Delhi. For seven days, all sorts of merrymaking continued at Mehrauli with Jhoolas (swings) in the mango groves, cock fighting and bull baiting, kite-flying, wrestling and swimming bouts. Amidst the celebrations, the chadar made of flowers was offered at the shrine. The secular-minded Mughal emperor ordered an offering in the shape of a floral pankha (ceremonial fan) at the Yogmaya Temple.[4]
Seeing the response of the people and sensing the enthusiasm generated, it was decided that the festival would be held annually after the rains, and that people of all communities would make similar offerings at the holy sites. The Darbar was also shifted to Mehrauli for the 7 days of the Festival. The festival reached its pinnacle during the reign of Bahadur Shah Zafar. Bahadur Shah Zafar went to celebrate “Phool Walon Ki Sair” even during the 1857 Siege of Delhi. This was the last “Phool Waalon Ki Sair” under the Mughals.[5][6][7]
