Today, Budaun may be a non- descript town in the district of the same name in the western Uttar Pradesh, history weighs heavily on it.
About 235 km from Delhi, Budaun came into prominence when it became a centre of power during the reign of Iltutmish of the Slave Dynasty of Delhi Sultanate. Iltutmish, who ruled from AD 1210 to 1236, served as the governor of Badaun under the Delhi Sultan Qutab ud-din Aibak before becoming the Sultan. It was at Badaun where Tajuddin Yalduz, successor of Muhammad of Ghor in Ghazni and a rival of Iltutmish, was beheaded on the instruction of the latter in 1216. The imposing Shamsi mosque in the town was commissioned by Iltutmish.
Budaun was the birthplace of Hazrat Nizamuddin Auliya (1236-1325), one of the most famous Sufi saints of Chisti order. His Dargah in Delhi attracts a large number of visitors.
Alauddin Alam Shah, the last ruler of Sayyid Dynasty of the Delhi Sultanate, found it better to retire in Badaun after abdicating the throne in favour of Buhlul Khan Lodi who founded a new dynasty which came to be known as the Lodi dynasty.
The tombs of Alam Shah and his mother are an Archaeological Survey of India (ASI) protected monument in Badaun.
