The Indian union territory of Jammu and Kashmir consists of two divisions: Jammu Division and Kashmir Division, and is further divided into 20 districts:
Prior to 1947, Kashmir was a princely state under the paramountcy of the British Indian Empire. The central part of the princely state was administratively divided into the provinces Jammu and Kashmir. In addition there were frontier districts and semi-autonomous jagirs (principalities). They were subdivided as follows:
The Gilgit district and the frontier ilaqas were administered by the British administration as the Gilgit Agency, which were returned to the princely state prior to the Partition of India.
After the partition of India and subsequent independence of India and Pakistan, in October 1947, following a rebellion coupled with a tribal invasion from newly independent Pakistan, the Maharaja of Jammu and Kashmir acceded to India in return for armed assistance. India and Pakistan fought the First Kashmir War that lasted through 1948, at the end of which large parts of the three western districts of Mirpur, Poonch and Muzaffarabad, the whole of the Gilgit Agency and the Skardu sub-district of Ladakh came under Pakistani control. The remainder of the princely state had been organised as a state of India under the name Jammu and Kashmir.
The territory under Indian control include:
The districts were reorganised by 1968, breaking up some of the larger districts. In 2006, eight new districts were created: Kishtwar, Ramban, Reasi, Samba, Bandipora, Ganderbal, Kulgam and Shopian.
In August 2019, the Jammu and Kashmir Reorganisation Act was passed by both houses of the Indian Parliament. The provisions contained in the bill reorganised the state of Jammu and Kashmir into two union territories; Jammu and Kashmir (union territory) and Ladakh with effect from 31 October 2019.
The Deputy Commissioner (DC) is the head of the district administration. They are responsible for overall administration and development activities in the district. The DC functions as District Magistrate (DM) for maintenance of law and order and as Collector for revenue administration. In the capacity of Collector, the DC oversees revenue administration, managing tasks such as revenue collection, land records maintenance, and implementation of government fiscal policies. The DC is usually an Indian Administrative Service (IAS) officer. The Deputy commissioner is assisted by Additional Deputy Commissioners, Assistant Commissioners and Sub-divisional magistrates. The districts are further divided into sub-districts and tehsils.
In 2018, BJP repeated it's old demand of creating 4 to 5 new districts in Jammu division which has 70% more area than Kashmir Division yet presently both have same number of districts, 10 each.
