Background of India Pakistan Wars
The India-Pakistan wars have a significant background in history. These wars lie in the problematic partition of British India in 1947. This partition created two different countries based on religious majorities. Nearly one-third of the Muslim population of India stayed in the new India. Inter-communal violence between Hindus, Sikhs, and Muslims resulted in between 200,000 and 2 million deaths, leaving 14 million people displaced. The princely state of Jammu and Kashmir, with a Muslim majority but a Hindu ruler, became the main topic of conflict. Pakistan aimed to rule over the territory, while India kept its accession to the Indian Union, leading to the First Kashmir War in 1947-48. Successive wars in 1965, 1971, and the 1999 Kargil dispute were caused by continuing tensions over Kashmir, cross-border terrorism, and regional dominance. These wars shaped both nations' national identities and military ideologies, leaving long-lasting effects on South Asian geopolitics.

Indo-Pakistan Wars and Disputes
Since 1947, India and Pakistan have subsequently engaged in four wars. primarily over the Kashmir region. The 1947-48 dispute ended in a tie. The 1965 war remains debated. The 1971 war, sparked by the Bangladesh independence movement, resulted in a decisive Indian victory. The 1999 Kargil War saw India reclaim territories. Also, the Siachen conflict (1984–2003) and the 2001–2002 India–Pakistan deadlocks have raised provincial pressures.
India and Pakistan have been involved in several wars and disputes since achieving independence in 1947:
First Indo-Pak War (1947-1948)
Clashed over the Kashmir territory soon after independence. Ended in a ceasefire and the establishment of the Line of Control (LoC).
History
The first dispute between India and Pakistan was known as the First Kashmir War. It took place in October 1947. The discord derived from the accession of the princely state of Jammu and Kashmir to India. After the partition by the British in 1947. Princely states were given three choices: accede to India and Pakistan or stay independent. The ruler of Jammu and Kashmir, Maharaja Hari Singh, opted to accede to India.
Dispute
The majority of Muslim inhabitants in Jammu and Kashmir, along with tribal Islamic parties supported by Pakistan, directed the occupation of some regions of the princely state. Confronting this danger, Maharaja Hari Singh sought military assistance from India and finally acceded to India. The matter was taken to the United Nations Security Council, resulting in Resolution 47 on April 22, 1948, and confirming the Line of Control.
A ceasefire was announced at 23:59 hours on January 1, 1949, with India having authority over two-thirds of Jammu and Kashmir and Pakistan gaining Gilgit-Baltistan and Azad Kashmir. The region ruled by Pakistan is often referred to as Pakistan-Occupied Kashmir (POK).
Second Indo-Pak War (1965)
Another conflict over Kashmir. Ended with the Tashkent Agreement in 1966, reconciled by the Soviet Union (Russia).
History
The Second Indo-Pak War in 1965 had origins in the lingering Kashmir conflict. Pakistan, bothered by memories of the 1947 war, tried to enter Kashmir through Operation Gibraltar, desiring to start an insurgency in Indian-administered locations.
Dispute
India reacted with a full-scale military operation against West Pakistan. The war lasted for 17 days. It witnessed significant losses on both sides. It featured some of the largest tank battles since World War II. Intervention by the Soviet Union (Russia) and the USA led to a ceasefire, with India having the upper hand due to Pakistan's provocation of insurgency.
Indo-Pak War of 1971 (Bangladesh Liberation War)
Flashed by the Bangladesh independence movement, directing the creation of Bangladesh. A decisive victory for India.
History
The Indo-Pak War of 1971 was also known as the Bangladesh Liberation War. The political turmoil between East and West Pakistan sparked it. Bangladesh, previously East Pakistan, sought independence due to conflicts between Yahya Khan, Sheikh Mujibur Rahman, and Zulfikar Ali Bhutto.
Dispute
Pakistan conducted Operation Searchlight, which led to widespread atrocities, prompting millions of Bengalis to flee to India. India interfered in support of the Bangladesh Liberation Movement. Pakistan's preventive strike on India started the war. Indian forces seized significant parts, and the Shimla Agreement later returned some areas to Pakistan. More than 90,000 Pakistani prisoners of war were taken, and Pakistan suffered substantial losses in the armed, naval, and air forces.
Kargil War (1999)
Discord in the Kargil district of Jammu and Kashmir. India regained power over the regions occupied by Pakistani forces.
History
The Kargil War in 1999 was mainly centered around the Kargil district of Kashmir. Pakistani armies entered the Line of Control (LoC).
Dispute
India replied by using both military and diplomatic actions. Within two months, Indian forces reclaimed the occupied ridges. The fear of escalation compelled the U.S. to pressure Pakistan to withdraw, leading to global isolation. Pakistan accepted over 4,000 deaths and a loss in the conflict, marking a notable defeat. The Kargil War stressed the threats associated with nuclear-armed neighbors.

Significant disputes and stalemates Between India and Pakistan
India and Pakistan have faced numerous significant conflicts and standoffs over the years. Primarily centered around the Kashmir issue. Other pressure issues include cross-border terrorism, water sharing under the Indus Waters Treaty, and ceasefire violations along the Line of Control.

2016 Uri Attack: India undertook retaliatory "surgical strikes" throughout the Line of Control in reply to a terrorist attack on an Indian Army camp in Uri, Kashmir. This step further increased pressure.
