Turkic rule

In 1203 AD, the first Muslim ruler, Muhammad Bakhtiyar Khalji, a Turk, captured Nadia and established Muslim rule. The political influence of Islam began to spread across Bengal with the conquest of Nadia, the capital city of the Sen ruler Lakshmana. Bakhtiyar captured Nadia in an interesting manner. Being made aware of the presence of a strong army of Lakshmana Sen on the main route to Nadia, Bakhtiyar proceeded instead through the jungle of Jharkhand. He divided his army into several groups, and he himself led a group of 17 horsemen and advanced towards Nadia in the guise of horse-traders. In this manner, Bakhtiyar had no problem in entering through the gates of the city. Shortly afterwards, Bakhityar's main army joined him and within a short while Nadia was captured. After capturing Nadia, Bakhtiyar advanced towards Gauda (Lakhnuti), another major city of the Sena kingdom, conquered it and made it his capital in 1205. In the following year, Bakhtiyar set out on an expedition to capture Tibet, but this attempt failed and he had to return to Bengal in poor health and with a reduced army. Shortly afterwards, he was killed by one of his commanders, Ali Mardan Khalji.[24] In the mean time, Lakshman Sen and his two sons retreated to Vikramapur (in the present-day Munshiganj District in Bangladesh), where their diminished dominion lasted until the late 13th century.
