1) Rather than Bengal or Bangla, "Bangalah" is the correct word. The non-political names of different parts of 'Bangalah' in the historical times are Bongo, Shomotot, Rarh, Barendra, Bakla, Bhati and some others. But, no name could be fixed to an area because of the lack of demarcation. Many of these localized names may have been given by the local Puthi-Shahityo poets or folk singers, and the locals gradually accepted the names.
2) Many of the Kingdoms in the historical times were named after their Capitals. Such as Delhi Sultanate, Gazhni Sultanate etc. The region between Indian NE and Uttar Pradesh was the Kingdom of Laksmanaboti (Lakkhanabati). Biswarup Sen vacated this Capital when Laksman Sen was defeated at the hands of Ikhtieruddin Khilji. The immigrant Turkic/Afghan Muslims started to mis-pronounce it Lukhnouti, instead. Hence, it became the country's name.
3) At a certain point of history, the overzealous newly arrived Muslims changed the name of the Capital to "GHORE." Why Ghore? It was because Ghore is the name of their original country in Afghanistan, and this is why its Sultan was called also Muhammed Ghori. Now, the name Ghore in Bengal could not be properly pronounced by the local Hindus. They started to mis-pronunce it as Gour. Since then it was Gour.
4) It continued until the Delhi Mughals fully captured this land in 1605. They named it "Sube Bangalah." This is the first time that the entire region between Indian NE and U.P started to be called Bangalah. After 1947, it was East Pakistan, but its people loved to call it Purbo Bangla. It was changed again by our warriors in 1971.
5) So, only this part of Bangla has the right to name it according to the old name. Pashim Bongo name should remain as it is, or it can unite with Bihar to be called Bihar. That Kolkatta-centric people have little right to claim their tiny Province to be named Bangla. How can it be when they chose to break away from the mainland Bengal in 1947?
