Well.Conflict started in 1947 when British left India and Pakistan was made.All the princely states had freedom to join India, Pakistan or remain independent.Pakistan was founded as a separate Muslim nation.Many states joined India and Pakistan except the state of Jammu and Kashmir.The king of the state,Maharaja Hari Singh was a hindu but the state had major Muslim population (71%). Pakistan was expecting Kashmir to join Pakistan due to Muslims and India expected it to join India as the state functioned under guidelines of British India prior Independence.Hari Singh was more inclined independent state.Pakistan seeing this,sent local rebels to invade and takeover Kashmir.As the assault begun, Hari Singh asked India for Independence.India at first did not and said that it cannot intervene in matters of other country and so Hari Singh signed an instrument of accession handing over Jammu and Kashmir to India and added a provision that after the war, people of the state will decide as to which side they want to be with.After signing, India sent its Army and fought the invaders.In 1948, India asked UN for assistance and a ceasefire was finally declared with Part Kashmir in Pakistan's control and part with The UN security council asked all Pakistani forces to leave Jammu and Kashmir along with rebels and Pakistani nationls.It also asked India to withdraw most of its men except a few to maintain law and order.The Indian troops were also needed to ensure smooth voting under the provision in which citizens would decide which side they want to be with.India agreed to withdraw if Pakistan will do first since it initiated the war..Pakistan rejected the proposal stating that it is unsure India would withdraw.No side withdrew and that sums up the dispute between the two countries.No voting was done as none of the two sides would withdraw.India gave the state of Jammu and Kashmir autonomy until its fate was decided.Autonomy included septate construction,seperate financial resources allocation and other things.The Government of India could not even implement a law in state with state's assembly's permission. Ever since then India found 3 wars with them. In1965 war, some 40,000 Pakistani soldiers dressed as locals and started settings up positions in various towns India got an early tip off and planned ahead.Pakistan and India fought hard and good with Pakistan capturing significant territory in Kashmir and Indian men entering Lahore and close to Pakistani capital Islamabad.Ceasefire was declared by UN. India won this war. In 1971 war: Pakistan was in two parts back then.East Pakistan (now Bangladesh) and west Pakistan.Due to not much freedom in east Pakistan,east Pakistan kind of became rebilliios and so Pakistani infantry started massacre against the population of east Pakistan especially targeting Hindus.Refugees started fleeing to India and so, India started to stop this massacre.India prepared for several months with tensions mounting in Pakistan that India will Attack it.As months passed,it was certain that India will attack and so Pakistan decided to bomb India first to gain upper hand (India was prepared and was waiting for Pakistan to initiate)As soon as the Pakistani bombs hit, India declared war with Indian Navy deploying its carriers and other assets destroying harbour, Indian Army and Air Force entering east Pakistan.The entire war lasted 13 days .97,000+ Pakistani troops were captured,new nation of Bangladesh was made and India capture 5,800sq miles of land in west Pakistan (current Pakistan) but later returned it as goodwill gesture. In 1999 War: Pakistani soldiers dressed as militants entered Indian land and set up posts in Himalayan mountains in winters.Before this,there was an understanding that both Nation abandoned their High Altitude outposts in harsh winter and come back in summer.Pakistan used this agreement to advantage and set up posts.The Battle was then initiated.Pakistan denied that it was its men who were engaged in battle but ID cards of dead soldiers indicated otherwise.The war was bloody as India decided not to cross the international border but attack the hills headon.India finally did capture the mountains . Pakistan denied its involvement and even refused to take bodies of its men who were then burried with honours by Indian Soldiers

This pretty much sums up
