This chapter provides a historical context of how coins represented sovereign and ritual authority for sultans or kings in medieval northern India. In medieval north India, coins were minted to facilitate commercial transactions and payments and conveyed hidden or sometimes overt messages before the Mughal rule. The authorities in the Sultanate of northern India strategically used coins to communicate informal decrees to remote and peripheral areas where royal forces might not be present to maintain the state’s control. Consequently, coins were a subtle strategy to extend the ruler’s influence. This study proposes that analysing the history of coins and currencies in relation to the political authority of the kings in medieval times could lead to a more comprehensive understanding of the state-building process in the second millennium. This approach transcends merely listing and describing coins and currencies; instead, historical research can reveal more detailed and insightful aspects of numismatic history.
