The conquest was aided by a Muslim saint known as Shah Jalal, who later ordered his disciples to scatter throughout eastern Bengal and propagate the religion of Islam.

Govinda was a conservative Hindu ruler of the Gour Kingdom, intolerant and harsh towards other faiths such as Islam, Buddhism and even certain denominations of Hinduism.

[4] There was a small minority of Muslim families living in the country, following the short-lived Azmardan Invasion in 1254 led by the Governor of Bengal, Malik Ikhtiyaruddin Iuzbak.

[5] The Gour Kingdom bordered the independent Bengali principality of Lakhnauti ruled by the Muslim Sultan Shamsuddin Firoz Shah of the Balban dynasty.

The war began when Burhanuddin, a Muslim living in the village of Tultikar, sacrificed a cow for his newborn son's aqiqah or celebration of birth.

After both men being punished, Burhanuddin and Nooruddin's brother, Helimuddin, travelled to lower Bengal where they addressed their issued with Sultan Shamsuddin Firoz Shah.

[9] When word of this reached Sultan Shamsuddin Firoz Shah, the commanded his nephew Sikandar Khan Ghazi to lead an army against the Raja.

The Bengali army, inexperienced in the foreign terrain which consisted of many low-lying hills and valleys, were brought to utter shame by Govinda's archers and had no option but to retreat back to Muslim Bengal to avoid casualties.

[10] Firoz Shah then turned to his Sipah Salar (commander-in-chief) Syed Nasiruddin as he realised that this undertaking was much bigger than he anticipated and he would need a larger and more skilled army.

[12][7] Govinda's family rejoiced over the three consecutive victories and his aunt Apurna, the queen-mother and wife of the previous Raja Govardhan, celebrated by building a large 20-acre water tank in Ambarkhana known as Rajar Mar Dighi.

From here the third battle was fought between Gour Govinda and the combined armies of Shah Jalal and Syed Nasiruddin, with the latter forces ultimately claiming victory.

The 12 saints who accompanied Nasiruddin are as follows: Gour and Taraf were then incorporated into Shamsuddin Firoz Shah's kingdom with Sikandar Khan Ghazi being the first Wazir of Sylhet.
