Kashmir conflict

The Jammu and Kashmir conflict (, ) is a dispute over the territory of Kashmir. The dispute is between India, Pakistan and China. India claims all of the region that was once a princely state which it considers it's territory. It currently controls about 43% of the territory, including most of Jammu, the Kashmir Valley, Ladakh, and the Siachen Glacier. India's claims are disputed by Pakistan, which controls about 45% of Jammu and Kashmir, including Azad Kashmir and Gilgit-Baltistan. Pakistan says there should be a referendum in Kashmir on whether the people want to join India or Pakistan, or become independent.
History.
The conflict started during the Partition of India (1947–48). On October 20, 1947, tribesmen backed by Pakistan invaded Kashmir. The Maharaja of Jammu &amp; Kashmir initially fought back but on 27 October appealed for assistance to the Governor-General Louis Mountbatten, who agreed on the condition that the ruler accede to India and that a plebiscite would be held afterwards, which was not. Once the papers of accession to India were signed, Indian soldiers entered Kashmir with orders to stop any further occupation, but they were not allowed to remove anyone from the state. India took the matter to the United Nations. The UN resolution asked Pakistan to vacate the areas it has occupied and asked India to assist the U.N. Plebiscite Commission to organize a plebiscite to determine the will of the people. Pakistan refused to vacate the occupied areas.
In 1947-8 India and Pakistan fought their first war over Jammu and Kashmir. Under United Nations' supervision, they agreed to a ceasefire along a line which left one-third of the state - comprising what Pakistan calls Azad Jammu and Kashmir, and the Northern Areas administered by Pakistan and two-thirds, Jammu, Ladakh and the Kashmir Valley, controlled by India. In 1972, under the terms of the Simla agreement, the ceasefire line was renamed the Line of Control. 
Although India claims that the entire state is part of India, it has been prepared to accept the Line of Control as the international border, with some possible modifications. Both the US and the UK have also favoured turning the Line of Control into an internationally-recognised frontier. 
But Pakistan has consistently refused to accept the Line of Control as the border since the predominantly Muslim Kashmir Valley would remain as part of India. Formalising the status quo also does not take account of the aspirations of those Kashmiris who have been fighting since 1989 for independence for the whole or part of the state.
Water dispute.
Another reason behind the dispute over Kashmir is water. Many rivers start in Kashmir. Some of them are tributaries of the Indus River basin, such as the Jhelum and Chenab River. These flow into Pakistan and are used for irrigation there. Other rivers like the Ravi, Beas River and the Sutlej flow into northern India.
One of the origins of the conflict is that with the Boundary Award of 1947, many of the Pakistani irrigation systems can be controlled from India. Pakistan has been afraid that India could stop the flow of rivers that start in Indian-controlled Kashmir and flow into Pakistan. This would harm the agrarian economy of Pakistan. The Indus Waters Treaty signed in 1960 resolved most of these disputes over the sharing of water.
Current status.
Today Kashmir is split, as follows:
Kashmir has been a source of conflict between India and Pakistan for more than 60 years. Currently a boundary - the Line of Control - divides the region in two, with one part occupied by India and one militarily administrated by Pakistan. India would like to formalise this status quo and make it the accepted international boundary. But Pakistan and Kashmiri activists reject this plan because they both want greater control over the region.
Map issues.
As with other disputed territories, each government issues maps depicting their claims in Kashmir as part of their territory, regardless of actual control. It is illegal in India to exclude all or part of Kashmir in a map. It is also illegal in Pakistan not to include the state of Jammu and Kashmir. Non-participants often use the Line of Control and the Line of Actual Control as the depicted boundaries, as is done in the CIA World Factbook, and the region is often marked out in hashmarks, although the Indian government strictly opposes such practices. When Microsoft released a map in Windows 95 and MapPoint 2002, a controversy was raised because it did not show parts of Kashmir as part of India as per Indian claim. However, all the neutral companies claim to follow the UN's map and over 90% of all maps containing the territory of Kashmir show it as disputed territory.
