I am surprised to see such a beautiful Minaar built by Sultan Saif ud Din Firoz Shah of Bengal sometime in 1480s. It is still well preserved. There was a time when Arabs and Abysinians had come to Bengal and made this land their permanent home. During the second half of 15th Century there were 8,000 Abysinian troops in the Bengal Army.
However, contrary to the statement given in the related posts you have sent, Firoz Shah was not an Abysinian and nor the Sultan after him, Qutubuddin Mahmud Shah. Rather, the latter was killed by one of his palace attendants whose name was Sidi Badr, a Khoja. Malik Andil was of Abysinian general of Bengal army, but he was at the border at the time of killing the Sultan.
He rushed to the Capital and the Emirs asked him to kill Sidi Badr. Sidi Badr was killed by him and he took over the Sultanate of Bengal. But, he himself was defeated and killed by his Prime Minister Syed Hussein Shah at a latter time, who was the descendent of an Arab migrant. Any way, Sultan Firoz Shah was not an Abysinian. He was a Bangali of Turkic origin. So, the title of the Minaar is a little misleading.
Now, another problem will arise from some posters. Why there are not any Abysinian words in Bengali? So, it is not a part of history, but only a story. Racism should be avoided at any cost when we study history. History should be read as it is.
