Two schemes of Muhammed Tughlaq that failed and made him extremely unpopular were:
1. Muhammed Tughlaq increased the taxation in the Doab (the territory between the rivers Ganga and Yamuna).
2. His decision to transfer his Capital from Delhi to Devagiri (Daulatabad) with a view to having the Capital situated in the middle of his kingdom. He was bent upon taking all the inhabitants of Delhi to the new Capital. Both of his schemes failed as people never accepted both the schemes of him.
