Err why would I believe that? As far as I know during Turko-Afghan rule in Bengal, most administrative and even military posts were held by Hindus and also bulk of semi-feudal land owners also were Hindus. The peasant class of Hindu and Muslim Bengalis suffered just as they suffered during British rule.
I would almost agree to what you said about Hindu domination in the administrative services during muslim rule. But, you have used this logic to conveniently disregard the history of immigration of Muslims in this land. What you said is not history.
Even if Hindus were in good positions during Muslim rule, it did not prohibit people from other poor Muslim countries to come to Bengal and get Khash land from the govt or get a job in the military or other deptts. Military and Justice Deptts were two fields where Muslims dominated.
What is your idea about US or other immigrations from a poor europe (perhaps, you know it was poor)? Did all of them go to USA to get a govt administrative service? They used to get land ownership in most of the cases. The same thing happened in Bengal, too. it was a wide country with a small population.
This vacuum was filled with the coming of new people, who would get a title on the land distributed by the central and local govts. doors were open to muslims in Bengal and all other parts of hindustan. It is very natural that Muslims would be attracted to go and settle in a country where the govt is run by the Muslims.
Bangali Muslims are a mixed blooded people of Turko-Afghan, Arab, Negro, Central Asians, Pathans, local Hindus and Budhists. Our Prophet did not teach us to distinguish between any two different races of people. But, the issue is to find out the correct history. Please read also a post I have written in another thread.
Re: Governors and Sultans of Bengal up to the Mughal Conquest
1) When I say Bengal, it includes today's Bangladesh, west Bengal, Bihar and Jharkhand and upto certain extent Orissa. The natural boundary of Bengal extended upto Teliagiri and Shakligiri Passes that separate Bengal from Ayudh and Hindustan.
2) These two narrow mountain passes were so important for the defence of Bengal that it was said in old days that a three-man team was good enough to repulse an invading army from the other side. Without passing through these two mountain passes it was impossible to come to Bengal without overcrossing the dangerous mountains of Rajmahal or without taking another route through north Bihar.
3) Moreover, the crisscrosses of small and big rivers of Bengal were an impediment for Delhi to continue with even a most passionate seize of Bengal. Flood water would force the invaders retreat out of Bengal.
4) Delhi was conqured by the Turks in 1192, and Bihar and northern Bengal in 1198 (1203 by some scholars). The first four Maliks or Kings of Khilji dynasty were assassinated. Muslim rule in Bengal was associated with many such killings, internal conflicts and palace coups.
5) Khilji is not a family title. There are many different nomadic Turks in the central asia including Afghanistan. Khilji, Khaliji or Khalji is one such group. Khilji Turks used to live a nomadic poor life in those areas. Lure of large grain fields, wealth and a good life in Hindustan and Bengal pushed these poor nomads to fight and immigrate into these lands of plenty,
6) From the very beginning, the Khilji Turks of Bengal opposed a direct rule by the Delhi Turks. So, one can see a hundred warfares between these two regions. Delhi Muslims thought Bengal Turks were their cousines with same bloodline and therefore, Bengal must be an extension of Delhi Sultanate. But, the Muslim Turks of Bengal fought vigorously to foil the efforts of Delhi.
7) So, in such a tug of war between the two forces, until about 1339 AD Bengal was ruled semi-independently by the settler Turks by keeping a nominal tie with Delhi Turks.
8) Fakhruddin Mubarak Shah raised the standard of rebellion and declared independence of Bengal in 1339 AD. This had resulted in many wars between the two Sultanate.
9) During this independent period not only the Turkic families, but also Negroite and Arab families had ruled over this region. There were considerable infusion of these two groups in Bengal.
10) Bengal retained its independence until 1539 AD when Pathan Sultan Sher Shah of Bengal himself became the Emperor of Hindustan. Before this event, Mughal Emperor Humayun was defeated by Sher Shah in two wars in Bihar and had to retreat to Iran.
11) This linkage with Delhi was again broken when Adil Shah or Mobarak Shah killed his own nephew, the grandson of Sher Shah, and seized the throne of Delhi in 1554 AD. The Pathan Subedar Shams al-Din Mohammad Shah of Bengal declared independence and rushed towards Delhi to avenge the killing of Sher Shah's grandson. But, he was defeated and killed in Allahabad by the forces of Adil Shah. His son Sultan Bahadur Shah declared himself the Sultan of Bengal and continued to defy Delhi.
12) North Indian retinues of Suri Dynasty vacated their possessions after Adil Shah was defeated in the 2nd battle of Panipath in 1556 AD at the hands of Humayun. Adil Shah fled to the east, but was killed in a war with Sultan Bahadur Shah of Bengal. But, his Pathan and north Indian retinues were permitted to come and settle in Bengal where their own people were still ruling this region.
13) After the killing of Pathan Sultan Daud Shah in 1576 AD, these Pathans led a continuous war against Delhi until 1605 AD when finally they were defeated and Bengal went under the Delhi Mughal rule.
14) There was a considerable infusion of north Indian muslims during this long period of war. In order to thwart the war efforts of the local rebel Muslim forces in Bengal, Akber took a policy of awarding farm lands, instead of paying cash salaries, to some of his own military people from north India to encourage settlment in Bengal. This had resulted in a considerable immigration of north Indian muslims in Bengal.
15) Since this time until 1757 this region was ruled by the Viceroys sent from or appointed by Delhi Mughals.
