Saadat Khan Burhan Ul Mulk, was the founder of Avadh Dynasty ,he was from a noble Saiyed family of Nishapur in Khurasan. His real name was Mir Muhammad Amin while Burhan Ul Mulk was his titles. He entered the Mughal court as a small 'Amil', however managed to obtain mansab under Farrukhsiyar and played an important role in the ascending of Muhammad Shah to the throne and overthrow Saiyed brothers. Thus earned the title of Saadat Khan Bahadur in 1720.He was assigned the subedari of Awadh as a reward in 1722 and was given the task of suppressing zamindars Sheikhzadas in Lucknow. The city of Lucknow was the stronghold of the Shaikhzadas, whose recalcitrant attitude was causing concern to the Mughal emperor. For establishing his supremacy as governor of Avadh, Saadat Khan made a diplomatic alliance with the Shaiks of Kakori . One night, Saadat Khan, with his chosen troops, surprise the Shaikhzadas who were defeated and reduced to submission, and the sword hanging in Shaikhan Darwaza was pulled down. The Panch Mahal and Mubarak Mahal, both palaces of the Shaikhzadas, were occupied by the governor at a nominal rent This event was followed by the submission of several chieftains and aggressive Zamindars of the Mughal authority. The Mughal emperor conferred on Saadat Khan the title of Burhanul-Mulk (symbol of the state). Saadat Khan consolidated his position very soon. Peace was now ensured for the habitants, and highways were secure for caravans. These factors resulted in the growth of trade and commerce. Irwin rightly says that Saadat Khan “was probably the first governor to make the power of central government felt through the province”. He mostly resided at Ayodha and Lucknow.


But he was unable to make any substantial change in administration because of strong opposition of Sheikhs. Sheikhs were supporters of Saiyed Brothers at the Delhi court, and the Nawab was instrumental in destroying their power. Finally Burhan Ul Mulk decided to move to Lucknow in 1732. He treacherously killed Sheikh Ahmad Husain and thus reducing the influence of Shekhs.
Burhan Ul Mulk could stay in Avadh only for a period of about six years before in 1735 he was summoned back to Delhi in the wake of Nadir Shah's invasion, where he died a natural death on 19 March 1739, and his son-in-law, Muhammad Maqim, who had been his deputy between 1724 and 1739, succeeded him.. Burhan Ul Mulk did not contribute much to the urbanization of Lucknow because mostly he was away from Lucknow and servicing exegencies. He modeled, developed and remodeled Panch Mahalla where he stayed whenever at Lucknow. However his sardars who were stationed in the city made permanent settlement which are still known by their names as mohallas. Buildings he got built are Pucca Pul and Machchi Bhawan. Areas which developed in Burhan Ul Mulk's time were Katra Jehangir, Katra Muhammad Ali, Katra Khuda Yar Khan, Katra Wafa Beg, Katra Abu Turab, Katra Bazan Beg, Sarai Mo'ali Khan and Ismailganj .He chose the fish as his emblem and it later became the most popular symbol of Avadh, appearing on gates, doorways and cornices of official and private building for more than two hundred years
