Who was the founder of the tughlaq dynasty?

The founder of the Tughlaq dynasty was a man named Ghiyas-ud-din Tughlaq. His other name was Ghazi Malik. He started to rule in the year 1320. He was the Sultan of Delhi. Before he was the sultan, he was a governor for another king. I read he was a very good soldier too. He was not the ruler for very long, only about five years. Hope this helps you out, mate.
