Northern Areas: Historical Facts
Before partition of the sub-Continent, the state of Jammu and Kashmir with a total area of 84471 square miles, was geographically divided into following three big regions:
1. Jammu Province (12,378 sq. miles)
2. Kashmir Province (8,539 sq.)
3. Frontier Province of Ladakh and Gilgit (63,554 sq)
In 1947, a part of the state gained independence and was called Azad Jammu and Kashmir, which has an area of 5,134 square miles. While 29,814 square miles chunk of the Frontier Province of Ladakh and Gilgit after winning freedom came under the administrative control of Pakistan through an agreement. This is the area now called Northern Areas. The rest of the Frontier province i.e. 3,3740 sq. miles area of Ladakh is under Indian occupation . The Northern Areas of Pakistan are source of global attraction for their heights and vast ranges of K-2, Hindukush, Pamir and the Himalayas.
Constitutional Position
* Historically these areas belong to Dogra State of Jammu and Kashmir. On March 29, 1935, the British government took possession of Gilgit Agency from the state government, through a lease agreement for 60 years. The British feared of the Soviet expansionist moves, and therefore wanted to have direct control in the region. During this period the state flag remained hoisted over residency along with the Union Jack. However by August 1, 1947, the areas were returned to the state government , because the British had decided partitioning of the Indian sub-continent.
