List of Wars Between India and Pakistan, Year, Cause, Outcome

The partition of British India in 1947 gave birth to two nations, India and Pakistan. The division, grounded in religious and political differences, led to widespread violence, displacement, and a bitter legacy. Since independence, India and Pakistan have fought four major wars, engaged in numerous military standoffs, and have experienced countless border conflicts and terrorist attacks. The article below includes the List of Wars Between India and Pakistan from the First Kashmir War of 1947 to the recent Operation Sindoor of 2025 including key facts, triggers, outcomes, and their broader implications.

List of Wars Between India and Pakistan

Since 1947, India and Pakistan have experienced several military confrontations, most of them rooted in the long-standing Kashmir dispute and cross-border tensions. These clashes have ranged from full-scale wars to limited strikes and standoffs, each with its own background, trigger, and outcome. The table below offers a List of Wars Between India and Pakistan over the years.

Major Wars Between India and Pakistan

First Indo-Pak War (1947–1948): First Kashmir War

• Duration: October 22, 1947 – January 1, 1949
• Cause: Accession of Jammu & Kashmir
• Outcome: Ceasefire brokered by UN, establishment of the Line of Control (LoC)
  

Background:
Following independence, princely states were given three choices: accede to India, join Pakistan, or remain independent. Maharaja Hari Singh, the ruler of Jammu and Kashmir, initially chose to remain independent. However, when Pakistani tribal militias invaded in October 1947, he sought help from India and signed the Instrument of Accession, making Jammu & Kashmir a part of India.

Course of War:
The Indian Army was airlifted into Srinagar and successfully pushed back the infiltrators. Key battles were fought in Uri, Baramulla, and Jammu. However, Pakistan retained control over a portion of the territory now known as Pakistan-occupied Kashmir (PoK).

Result:
A UN-mediated ceasefire came into effect on January 1, 1949. It led to the establishment of the LoC, dividing Jammu and Kashmir between the two nations. The Kashmir issue, however, remained unresolved and a perpetual flashpoint.

Second Indo-Pak War (1965)

• Duration: August-September 1965
• Cause: Dispute over Kashmir, Pakistani Operation Gibraltar
• Outcome: Tashkent Agreement (January 1966) – Status quo ante bellum
  

Background:
Pakistan initiated Operation Gibraltar, sending soldiers disguised as locals into Jammu and Kashmir to incite rebellion. The plan backfired as locals did not support the intruders, and the Indian Army responded with full-scale retaliation.

Course of War:
The conflict spread across the International Border. Major battles were fought in Lahore, Sialkot, and the Rann of Kutch. The Indian Army made significant gains, and both sides suffered heavy casualties.

Result:
After intense fighting lasting 17 days, a UN-mandated ceasefire was declared. The Tashkent Agreement, brokered by the USSR, restored pre-war positions. However, the war did not resolve the Kashmir dispute, and both nations claimed victory.

Indo-Pak War of 1971: Bangladesh Liberation War

• Duration: December 3-16, 1971
• Cause: Political crisis in East Pakistan; support for Bengali independence movement
• Outcome: Creation of Bangladesh, Decisive Indian victory
  

Background:
East Pakistan (present-day Bangladesh) had been agitating for autonomy. Following the denial of electoral victory to Sheikh Mujibur Rahman’s Awami League and subsequent military crackdown by West Pakistan, a refugee crisis emerged with over 10 million people fleeing to India.

Course of War:
India supported the Mukhti Bahini (freedom fighters) and launched military operations on both the eastern and western fronts. The Battle of Longewala in Rajasthan and naval blockade of Karachi were strategic successes.

Result:
On December 16, 1971, Pakistan’s Eastern Command surrendered in Dhaka with over 90,000 troops taken as prisoners of war. The war led to the birth of Bangladesh. The Shimla Agreement (1972) was signed, where India returned captured territory in the west in exchange for peace commitments from Pakistan.

Kargil War (1999)

• Duration: May-July 1999
• Cause: Pakistani infiltration into Kargil sector
• Outcome: India regained all lost territory, diplomatic victory
  

Background:
Pakistani troops and militants infiltrated into Indian positions along the LoC in the Kargil region. Their aim was to cut off National Highway 1A, thereby disrupting Indian logistics in Siachen and Kashmir.

Course of War:
India launched Operation Vijay, combining infantry assaults, artillery bombardments, and air strikes. Major battles took place at Tololing, Tiger Hill, and Batalik.

Result:
Indian forces successfully recaptured all the occupied positions. International pressure, especially from the United States, forced Pakistan to withdraw. The war exposed Pakistan Army’s duplicity, as then-Prime Minister Nawaz Sharif was kept unaware of the operation by the military leadership.

Other Major Conflicts and Military Engagements

India and Pakistan have experienced a series of high-stakes military confrontations since their independence in 1947, with several conflicts emerging even in the post-Kargil era. While full-scale wars have been largely avoided since 1999, tensions have remained high due to terrorism, border conflicts, and strategic rivalries. The table below summarizes key India-Pakistan military engagements and operations from 1984 onwards, highlighting their causes, actions taken by India, and their outcomes.

Operation Sindoor (2025)

Operation Sindoor 2025 was launched in direct response to the tragic Pahalgam terror attack on April 22, 2025, which claimed the lives of 26 innocent civilians. India initiated a swift and coordinated military offensive on May 7, 2025. The operation spanned approximately four days and concluded on May 10, 2025. The primary objectives of this mission were to dismantle terror infrastructure across the border, and deliver a strong message of deterrence to hostile elements.
