When Pakistan Became an Islamic Republic: The Date and the Story Behind It
Every Pakistani schoolchild knows 14 August 1947 — but the day Pakistan became an Islamic republic came nearly nine years later. This is the story of that date: how 23 March 1956 was chosen, what happened on the day, and why it is still a national holiday.
Quick answer: Pakistan became an Islamic republic on 23 March 1956, when its first constitution — 234 articles adopted by the Constituent Assembly — came into force. The date was chosen to coincide with the 16th anniversary of the 1940 Pakistan Resolution, and Iskander Mirza was sworn in as the country’s first President the same day.

The Date: 23 March 1956
The road to the date ran through three milestones in early 1956: the draft constitution was introduced in the Constituent Assembly on 9 January, adopted on 29 February (a leap-year date), and given the Governor-General’s assent on 2 March. It was then held for enforcement until 23 March — a date with deep symbolic weight. Our complete guide to Pakistan becoming an Islamic republic covers the full constitutional story.
What Happened on the Day
On 23 March 1956, Pakistan’s status as a British dominion ended. Queen Elizabeth II ceased to be Queen of Pakistan; the Governor-General’s office was abolished; and Iskander Mirza — the last Governor-General — took the oath as the first President of Pakistan. The new constitution’s 234 articles, in 13 parts and 6 schedules, established a parliamentary republic with a 300-member unicameral National Assembly (150 seats each for East and West Pakistan), a Muslim president as ceremonial head of state, and the Objectives Resolution as preamble. Official ceremonies marked the inauguration — though the Awami League, which had walked out when the constitution was adopted, boycotted them.
Why This Date Was Chosen
23 March was already sacred in Pakistan’s political calendar: on that day in 1940, the All-India Muslim League adopted the Pakistan Resolution at Minto Park, Lahore, formally demanding a separate Muslim homeland. Enforcing the constitution on the resolution’s 16th anniversary fused the two founding moments — the demand for Pakistan and its constitutional birth. The day was declared Republic Day, a national holiday with a parade.
The Legacy: Pakistan Day
The 1956 constitution itself lasted only until 7 October 1958, when Mirza abrogated it and imposed martial law. But the date outlived the document: 23 March is still celebrated every year as Pakistan Day, marked by the national military parade in Islamabad and the conferral of civil awards. And the name the constitution gave the country — “Islamic Republic of Pakistan” — survived every subsequent constitution, including the 1973 constitution in force today.
