In 224 yrs, between 1724-1948 of Nizam rule, Hyderabad State was made up of sixteen districts, grouped into four divisions. Aurangabad division included Aurangabad, Beed, Nanded, and Parbhani districts; Gulbarga division included Bidar, Gulbarga, Osmanabad, and Raichur Districts; Medak division included Atraf-i-Baldah (HYD city), Mahbubnagar, Medak, Nalgonda, and Nizamabad districts, and Warangal division included Adilabad, Karimnagar, and Warangal districts. Nizam gifted away coastal Andhra to French in 1752, later East India Company acquired it in 1766.
During 224 yrs of Nizam rule, only HYD city was directly ruled by Nizams and remaining districts/villages were mostly under the rule of local hindu rulers - patels, doralu, deshmukhs, karnalu, zamindars, etc. and indirectly controlled by Nizams. Being a capital of Hyderabad State, Hyderabad city attracted people from all districts - Kannada, Marathi, and Telangana people. Also attracted people from neighboring British provinces - mostly Andhra, Tamil and Oriya people. All these people have contributed to the social and cultural fabric of present Hyderabad.
In 1956, two divisions Aurangabad and Gulbarga are merged with Maharastra and Karnataka respectively and the other two divisions Medak and Warangal are merged with Andhra region of erstwhile Madras Province to form Andhra Pradesh. In last 54 yrs, Hyderabad city has attracted people from all the districts of Andhra Pradesh and also other states - again mostly from Karnataka, Maharastra, Tamilnadu, Orissa. All these people have made Hyderabad as their home and adopted the pre-1956 culture and also influenced pre-1956 culture with the culture of their origin. And majority of the present Hyderabad citizens do not have any social and cultural relations with Telangana districts. Hyderabad and Telangana regions have got different identities.
One recent example to show the different identities is - After 9th Dec. incidents, Mr. G.Kishan Reddy (Amberpet - HYD city MLA) did not resign where as his partyman, Mr.Y.Laxminarayana(Nizamabad - Telangana MLA) has resigned - they acted according to the sentiments of the people they represent. Because BJP and Mr. Kishan Reddy were not confident of winning the seat again in by-elections as there is no strong telangana sentiment in Amberpet and Hyderabad. They very well know that Hyderabad and Telanagna got different identities and sentiments. Majority of people do not want to join separate telangana, if the A.P state gets bifurcated.
Another recent example is - in 2009 elections, TDP contested elections in alliance with TRS by changing their stand on Telangana issue and Hyderabad people have totally rejected TDP-TRS combine. TDP did not get a single MLA seat in greater hyderabad and Congress and MIM sweeped all MLA seats. Where as in Telangana TDP-TRS combine is a hit and TDP gained a lot and TDP-TRS combine got more MLA seats than Congress.
If we go by they history, culture, society, and democratic demand of the people of Hyderabad and Telangana, we should create two separate states/administrative entities - Hyderabad and Telangana - when Telangana region gets separated from Seemandhra region of Andhra Pradesh.
