Islamic Republic of Pakistan in the context of "Prime Minister of Pakistan"

Emperor (or Empress) of India was a title used by British monarchs from 1 May 1876 (with the Royal Titles Act 1876) to 22 June 1948 to signify their sovereignty over the British Indian Empire as its imperial head of state. The image of the Emperor or Empress appeared on Indian currency, in government buildings, railway stations, courts, on statues, etc. Oaths of allegiance were made to the Emperor or Empress and the lawful successors by the governors-general, princes, governors, commissioners in India in events such as imperial durbars.

The title was abolished on 22 June 1948, with the Indian Independence Act 1947, under which George VI made a royal proclamation that the words "Emperor of India" were to be omitted in styles of address and from customary titles. This was almost a year after he became the titular head of the newly partitioned and independent dominions of India and Pakistan in 1947. These were abolished upon the establishment of the Republic of India in 1950 and the Islamic Republic of Pakistan in 1956.

The partition of India in 1947 was the division of British India into two independent dominion states, the Union of India and Dominion of Pakistan. The Union of India is today the Republic of India, and the Dominion of Pakistan is the Islamic Republic of Pakistan and the People's Republic of Bangladesh. The partition involved the division of two provinces, Bengal and the Punjab, based on district-wise non-Muslim (mostly Hindu and Sikh) or Muslim majorities. It also involved the division of the British Indian Army, the Royal Indian Navy, the Indian Civil Service, the railways, and the central treasury, between the two new dominions. The partition was set forth in the Indian Independence Act 1947 and resulted in the dissolution of the British Raj, or Crown rule in India. The two self-governing countries of India and Pakistan legally came into existence at midnight on 14–15 August 1947.

The partition displaced between 12 and 20 million people along religious lines, creating overwhelming refugee crises associated with the mass migration and population transfer that occurred across the newly constituted dominions; there was large-scale violence, with estimates of loss of life accompanying or preceding the partition disputed and varying between several hundred thousand and two million. The violent nature of the partition created an atmosphere of hostility and suspicion between India and Pakistan that plagues their relationship to the present.

The Government of Pakistan (abbreviated as GoP; constitutionally known as the Federal Government, commonly known as the Centre) is the national authority of the Islamic Republic of Pakistan, a federal republic located in South Asia, consisting of four provinces and one federal territory. The territories of Gilgit-Baltistan and Azad Kashmir are also part of the country but have separate systems and are not part of the federation.

Under the Constitution, there are three primary branches of a government: the legislative, whose powers are vested in a bicameral Parliament; the executive, consisting of the president, aided by the Cabinet which is headed by the prime minister; and the judiciary, with the Supreme Court.

The Parliament of Pakistan is the supreme legislative body of the Islamic Republic of Pakistan. It is a bicameral federal legislature, composed of the Senate and the National Assembly, with the President of Pakistan as the head of the legislature. The president, upon the advice of the Prime Minister, has full powers to summon and prorogue either house or a joint session of Parliament or to dissolve the National Assembly.

The parliament's both houses convene at the Parliament House within the governmental Red Zone of Islamabad, the federal capital. Both houses of the parliament have their own separate chambers; and in case of a joint session, the National Assembly chamber is used.

The President of Pakistan is the head of state of the Islamic Republic of Pakistan. The president is the nominal head of the executive and the federal parliament, the first citizen of the country, and the supreme commander of the Pakistan Armed Forces. Serving as the ceremonial head of the federation, the president is bound to act on advice of the prime minister and the federal cabinet. Asif Ali Zardari is the 14th and current president, having assumed the presidency on 10 March 2024.

The office of president was created upon the proclamation of Islamic Republic on 23 March 1956. The then serving governor-general, Major General Iskander Mirza, assumed office as the first president. Following the 1958 coup d'etat, the office of prime minister was abolished, leaving the Presidency as the most powerful office in the country. This position was further strengthened when the 1962 Constitution was adopted. It turned Pakistan into a Presidential Republic, giving all executive powers to the president. In 1973, the new Constitution established Parliamentary democracy and reduced the president's role to a ceremonial one. Nevertheless, the military takeover in 1977 reversed the changes. The 8th Amendment turned Pakistan into a semi-presidential republic and in the period between 1985 and 2010, the executive power was shared by the president and prime minister. The 18th Amendment in 2010 restored Parliamentary Democracy in the country, and reduced the presidency to a ceremonial position.
