Invasion of Nadir Shah

In February 1739, the Persian emperor, Nader Shah decided to conquer India. Due to poor tactics, Muhammad Shah's army was easily defeated, and Nader Shah triumphantly entered Delhi within the span of one month, where he had the Khutba read in his name[citation needed]. In the violence that followed, more than 30,000 civilians were killed by the Persian troops, forcing Muhammad Shah to beg for mercy and handing the keys to his treasury[citation needed]. In response, Nader Shah agreed to withdraw, but Muhammad Shah paid the consequence - handing over the keys of his royal treasury and losing even the Peacock Throne, along with the Koh-i-Noor and Darya-ye Noor diamonds, to the Persian emperor
