head of government, the holder of the highest office in the government of a sovereign state, who also exercises practical political power. Some heads of government are technically holders of the second highest office in a country, the highest office being occupied by a ceremonial head of state who is considered in some way separate from or above normal politics and who symbolizes the ideal unity of the state.

A head of government acts as a country’s chief executive. The powers associated with such an office frequently include but are not limited to: appointing leaders of major government agencies; dissolving parliament or a national legislature and calling a national election; setting major foreign policy goals or initiatives; making treaties and other agreements with other countries or international organizations; serving as commander in chief, or supreme commander, of a country’s armed forces; and appointing or nominating judges to a country’s courts. Some countries reserve certain executive powers for the head of state rather than the head of government. For example, in India, where the prime minister is the head of government and the president is the head of state, the president has the power to appoint judges to the country’s supreme court.

In a democracy, the head of government is elected directly by popular vote or indirectly by voter proxies, as in the case of the electoral college system of the United States. The position of head of government in nondemocratic or semidemocratic countries may be inherited, as in the case of monarchies, or appointed or self-appointed, as in military dictatorships.

Most democracies are structured around both a head of government and a head of state. A large number of democratic parliamentary systems have separate offices for a president and a prime minister, with distinct powers and different electoral processes reserved for each. Presidents are more often elected directly by popular vote, while prime ministers assume their office by virtue of their leadership of a political party that wins a plurality of legislative seats (either by direct election or by joining a legislative coalition).

A parliamentary system that includes a head of state who also holds many or most of the chief executive powers is generally known as a semipresidential system. In France, for example, the president is the head of state and has the power to personally choose the prime minister, who is the head of government.

In a constitutional monarchy, the position of head of state is inherited on the basis of membership in a certain (royal) family. Constitutional monarchies are generally structured (either legally or through deliberately constructed norms) so as to insulate the head of state from the politics of governance. The head of state is thus expected to be entirely or mostly apolitical. In constitutional monarchies such as the United Kingdom, for example, the head of state generally keeps private any and all opinions on political issues and the conduct of governments. However, some constitutional monarchs are not as strictly separated from politics. For example, in Thailand constitutional monarchs have sometimes endorsed or legitimized the overthrow of governments and the actions of military dictatorships.

King Salman ibn AbdulazizSalman ascended to the throne more than 60 years after the death of his father, Ibn Saud, who founded the country. He designated his son, Mohammed bin Salman, as his successor, making Salman the last of his generation to rule Saudi Arabia.

In semiconstitutional or absolute monarchies, the monarch has the right to exercise or distribute responsibility for state executive functions. The monarch may choose (or be legally required) to appoint a separate head of government. For example, the absolute monarch of Saudi Arabia has often chosen to act as the country’s prime minister, but in 2022 King Salman bin Abdulaziz appointed his heir apparent, Crown Prince Mohammed bin Salman, to that office. In the semiconstitutional monarchy of Qatar, the ruling emir is required by the constitution to appoint a prime minister.

In countries governed by an authoritarian system, the head of government is chosen through a process that is closed to the public at large. In countries whose government is dominated by a single political party—as in many communist countries—the head of the party is sometimes effectively, if not officially, the head of government.

In military dictatorships, the leader of the military generally occupies one or both of the offices of head of state and head of government. Military dictators may appoint a nominal head of government but will generally reserve some or all of the executive powers of governance for themselves.
