Why Muhammad bin tughlaq was called mad man of history?

Muhammad bin Tughlaq, the Sultan of Delhi in the 14th century, is often referred to as the "madman of history" due to his erratic and ambitious policies that frequently backfired. His attempts to implement radical reforms, such as introducing a token currency and shifting the capital to Daulatabad, led to widespread chaos and suffering. While some of his ideas were innovative, their execution often lacked practical consideration, resulting in instability and dissatisfaction among his subjects. This combination of visionary ambition and disastrous outcomes has led historians to label him as a madman.
