Alauddin Ali Shah
Alī Mubārak, who ruled as Alauddin Ali Shah (c. 1290–1342), was an independent sultan of Lakhnauti in Bengal. After serving at Delhi, he fell out of favour and went east as army minister to Qadar Khan, the Tughluq governor there. When Qadar Khan died in 1339, Ali killed his deputy and seized the province and took the throne.
He then fought a triangular war with the rulers of Sonargaon and Satgaon, until in 1342 Shamsuddin Ilyas Shah defeated and killed him and took Lakhnauti.
