Don't be a noob, I said Arab Muslim traders arrived in Rangpur through China. You know very well about the silk route. Arab traders had been traveling through China for centuries, if not millenniums. The Southwest silk route follows the course of Brahmaputra. Brahmaputra flows through Rangpur division as Jamuna, before meeting with Ganges/Padma near Rajshahi and later with Meghna and eventually falls into Bay of Bengal near Noahkhali. Noahkhali is also near to Chittagong which was a major sea port in maritime Silk route.
Being a noob is one thing, being an ignoramus is another.
If you have not been following the conversation, try to pay attention now.
The Brahmaputra-Ganges confluence was not a major effluent of the Ganges; it was the minor one. It was not big enough or deep enough to encourage exploitation of the dense forest in which the entire Samatata and Jessore areas, southern Varendra, to stretch a point, were covered.
I certainly agree that there was traffic in goods from south China through the Brahmaputra valley through to the main Silk Road which traversed Persia, Khurasan, later, the Khwarezm Shahi, through the Turkish march lands into China, and that this traffic existed before Khurasan did, or the Khwarezm Shahi, or any ethnicity called the Turks, as far back as the days when the population of those tracts were Scythian, Pahlavi and Kushan. But if you had any information or knowledge about trans-Himalayan commerce, you would have known that it took place as a series of hand-offs, through various tribes arranged paralle to the watershed of the Himalayas. Nobody made an end-to-end trip at that end; it was a system of goods passed on from one tribe to another, in exchange for other goods moving in the reverse direction.
Such trade was seen and documented in the Arunachal area, and also, as you should know, in the Chakma tracts, and perhaps still is. So goods from the Brahmaputra valley reach deep into the hills where the Chakmas live, without paying tolls, tributes or taxes on the way, and in the same tribe-to-tribe way.
You might like to re-think your justification in the light of these facts.
How did you deduce this conclusion that the Khaliji (I am not talking about Chaghtai) Turks from Gharmsher of eastern Afghanistan) were very very tiny in those days when I find in history books that there were at least 400,000 arrival during the first few months after Bengal was conquered by them. Before Bengal Bihar was already at their disposal. Most were dependents who were brought to a happy land where all those half-educated and otherwise poor Khalijis became the overlord.
You will get a good idea of the percentage of completely alien new arrivals with a new look and religion if you can almost correctly find out the probable number of local Hindu population in north Bihar and Bengal.
Evidently you haven't read Eaton. I suggest you re-read it, or read it for the first time if you have not already done it. @
kalu_miah actually has done a brilliant job of reproduction of relevant sources. Perhaps his strength is not in evaluation and explanation.
I wonder which of these were converts, in the main, and which of these were excluded, according to the weird theories that I have seen being put forward:
