India–Pakistan Conflict: Historical Overview

 

Indo-Pakistani wars and conflicts

Since the partition of British India in 1947 and the creation of the independent nations of India and Pakistan, the two countries have engaged in multiple wars, military conflicts, and standoffs. The primary source of tension has been the longstanding dispute over the region of Kashmir, along with issues related to cross-border terrorism.

An exception to this pattern was the Indo-Pakistani War of 1971, which was not directly related to Kashmir. Instead, it was triggered by the Bangladesh Liberation War in then East Pakistan, where India's intervention ultimately led to the creation of a new nation — Bangladesh.

The First India–Pakistan War (1947–1948): Overview

The First India–Pakistan War began in October 1947, shortly after the partition of British India. The conflict was sparked by Pakistan’s fear that Maharaja Hari Singh, the Hindu ruler of the princely state of Jammu and Kashmir—a region with a Muslim-majority population—would choose to accede to India.

At the time of partition, princely states were given the option to join India, Pakistan, or remain independent. Amid this uncertainty, tribal militias from Pakistan, backed by the Pakistani army, invaded Kashmir. In response, Maharaja Hari Singh signed the Instrument of Accession to formally join India and requested military support.

India deployed troops to defend the region, leading to a full-scale conflict between the two nations. On 22 April 1948, the United Nations Security Council passed Resolution 47, calling for a cease-fire and a future plebiscite.

A formal cease-fire was declared at midnight on 1 January 1949. The war resulted in the division of the region:

• India gained control over about two-thirds of Jammu and Kashmir, including the Kashmir Valley, Jammu, and Ladakh.

• Pakistan retained control of approximately one-third, known as Azad Kashmir and Gilgit-Baltistan—collectively referred to as Pakistan-administered Kashmir.

The cease-fire line eventually became known as the Line of Control (LoC), which still exists as the de facto border between the two countries in the region.

Indo-Pakistani war of 1965

This war began as a result of Pakistan's Operation Gibraltar, a military strategy aimed at sending Pakistani forces into Jammu and Kashmir to incite an uprising against Indian rule. In response, India launched a full-scale military assault on West Pakistan.

The war lasted 17 days and resulted in thousands of casualties on both sides. It was notable for featuring one of the largest deployments of armored vehicles and the biggest tank battle since World War II.

The conflict ended after a ceasefire was declared, largely due to diplomatic efforts by the Soviet Union and the United States. This led to the signing of the Tashkent Declaration.

At the time the ceasefire was declared, India held a military advantage over Pakistan.

Indo-Pakistani war of 1971

This war was different from previous India-Pakistan conflicts because it did not center around the Kashmir issue. Instead, it was triggered by a political crisis in East Pakistan (now Bangladesh), where Sheikh Mujibur Rahman, the leader of East Pakistan, was in conflict with Yahya Khan and Zulfikar Ali Bhutto from West Pakistan.

The conflict escalated following Operation Searchlight and widespread atrocities in East Pakistan, leading to about 10 million Bengali refugees fleeing to India. In support of the Bangladesh liberation movement, India intervened militarily.

After a pre-emptive strike by Pakistan, full-scale war broke out. Pakistan launched attacks along India’s western borders, but the Indian Army successfully held its ground and launched a counteroffensive, capturing around 15,010 square kilometers of Pakistani territory in Kashmir, Punjab, and Sindh. However, this land was returned to Pakistan after the war as part of the Simla Agreement of 1972, demonstrating India’s goodwill.

The war lasted just about two weeks, culminating in the surrender of Pakistani forces in East Pakistan to the joint Indian and Bangladeshi command. This led to the creation of the independent nation of Bangladesh. Over 90,000 Pakistani troops surrendered, making it one of the largest surrenders since World War II.

According to a Pakistani author, the country lost half its navy, a quarter of its air force, and a third of its army during the war.

Kargil War (1999)

This war was different from previous India-Pakistan conflicts because it did not center around the Kashmir issue. Instead, it was triggered by a political crisis in East Pakistan (now Bangladesh), where Sheikh Mujibur Rahman, the leader of East Pakistan, was in conflict with Yahya Khan and Zulfikar Ali Bhutto from West Pakistan.

The Kargil War (1999) – India-Pakistan Conflict Summary in English:

This conflict between India and Pakistan was relatively limited in scale compared to previous wars. It occurred in early 1999, when Pakistani troops, along with militants, infiltrated across the Line of Control (LoC) and occupied Indian military positions in the Kargil district of Jammu and Kashmir.

In response, India launched a full-scale military and diplomatic operation to push the intruders back. After two months of intense fighting, Indian forces successfully recaptured nearly 75% to 80% of the infiltrated area, including key strategic high-altitude ridges.

As the fighting continued, the international community, especially the United States, put strong diplomatic pressure on Pakistan to withdraw its forces, fearing a large-scale escalation that could lead to full-scale war. This pressure, combined with Pakistan’s fragile economy, forced a retreat.

The morale of the Pakistani forces dropped significantly, particularly among the Northern Light Infantry, which suffered heavy casualties. Pakistan's government initially refused to acknowledge its involvement and even declined to accept the bodies of fallen soldiers, leading to public outrage and protests in the Northern Areas of Pakistan.

Later, Pakistan’s then-Prime Minister Nawaz Sharif admitted that more than 4,000 Pakistani soldiers had died, and acknowledged defeat. By the end of July 1999, the conflict had ended, marking a clear military and diplomatic victory for India, and a major defeat for the Pakistani Army.

India-Pakistan conflict (2025)

The 2025 India–Pakistan conflict was a brief armed confrontation that erupted on 7 May 2025, following a series of escalating events between the two nuclear-armed neighbors.

The conflict began when India launched missile strikes on Pakistan under Operation Sindoor, claiming it was a retaliatory action for the Pahalgam attack on 22 April, where 26 civilians (mostly tourists) were killed by militants in Indian-administered Kashmir. India blamed Pakistan for supporting cross-border terrorism, an accusation that Pakistan denied.

Key Developments:

• Operation Sindoor (India):
  India claimed its missile strikes targeted terrorist camps and infrastructure belonging to Jaish-e-Mohammed (JeM) and Lashkar-e-Taiba (LeT). India insisted no Pakistani military sites were hit.

• Pakistan's Response:
  Pakistan countered the claims, stating that the Indian strikes hit civilian areas, including mosques, resulting in the deaths of 31 civilians.

• Escalation:
  In the days that followed, border skirmishes and drone strikes occurred.
  On 10 May, Pakistan launched its own military response, Operation Bunyan al-Marsus, targeting Indian military bases.

• Retaliation by India:
  India expanded Operation Sindoor to include Pakistani military installations, intensifying the conflict.

Significance:

This conflict was notable for being the first drone war between India and Pakistan, marking a new chapter in modern warfare between the two countries. Despite being short-lived, the conflict raised significant concerns globally due to the nuclear capabilities of both nations.
