A government is the set of organised institutions—legislature, executive, and judiciary—through which the will of the state is articulated, enforced, and adjudicated. In classical political theory the government is distinguished from the state: the state is the permanent abstract sovereign entity (the Montevideo Convention, 1933, Article 1 lists population, territory, government, and capacity to enter relations as its constituents), while the government is its transient agent. International law recognises this distinction sharply—a change of government, even by revolution, does not extinguish the state's continuity of obligations, a principle affirmed in the Tinoco Arbitration (Great Britain v. Costa Rica, 1923), where Chief Justice Taft held that the Tinoco regime's acts bound the successor government regardless of its constitutional legitimacy. Government is thus the fourth Montevideo element and the organ that supplies a state with the "capacity to enter into relations with other states."
Governments are classified along several axes. By the fusion or separation of legislative and executive power they are parliamentary (the executive is drawn from and accountable to the legislature, as in India under Articles 74–75 and the United Kingdom) or presidential (a fixed-term executive elected separately, as under Article II of the US Constitution). By the distribution of power between centre and units they are unitary (United Kingdom, France) or federal (India's quasi-federal scheme under the Seventh Schedule, the United States, the Federal Republic of Germany). The criterion of recognition further divides governments into de jure (legally constituted and recognised) and de facto (in effective control but without full legal title)—a distinction central to the Tinoco and Luther v. Sagor (1921) jurisprudence. Recognition doctrines themselves split between the constitutive theory (recognition creates statehood/legitimacy) and the declaratory theory (it merely acknowledges an existing fact, the Montevideo position).
In contemporary practice the question of which entity is the lawful government carries acute consequences. The Estrada Doctrine (Mexico, 1930) holds that states should not pass judgment on the legitimacy of foreign governments, while the Tobar Doctrine denied recognition to governments seized by unconstitutional means. As of 2026 contested recognition persists in cases such as the rival claims over Venezuela, the status of the Taliban administration in Afghanistan (controlling territory since 2021 yet largely unrecognised), and Myanmar's post-2021 military junta versus the National Unity Government. The United Nations Credentials Committee, not a recognition organ per se, frequently becomes the arena where these disputes are decided, as it did over Afghan and Myanmar seats.
For the examinations this concept straddles General Studies/Polity and International Law and International Relations papers. Polity questions test the state–government distinction, classifications (parliamentary vs presidential, unitary vs federal), and the doctrine of collective responsibility. International law sections probe state succession, the continuity of obligations through government change (Tinoco), de jure/de facto recognition, and the constitutive versus declaratory debate. A frequent FSOT and UPSC angle asks candidates to explain why the fall of a regime does not relieve a state of its treaty and debt obligations—the core of governmental as opposed to state identity.
Example
In 1923, the Tinoco Arbitration held Costa Rica bound by contracts of the deposed Tinoco regime, establishing that a change of government does not discharge the state's continuing international obligations.
Frequently asked questions
The state is the permanent sovereign entity—one of the four Montevideo (1933) elements—while the government is its transient agent. A change of government does not extinguish the state or its obligations, as the Tinoco Arbitration (1923) confirmed.
