Military junta

A military dictatorship is a type of dictatorship where supreme power is held and exercised by the armed forces. Military dictatorships are led by either the ranking commander-in-chief (i.e. a military dictator) or by a council of military officers known as a military junta. They are most often formed by military coups or by the empowerment of the military through a popular uprising in times of domestic unrest or instability. The military nominally seeks power to restore order or fight corruption, but the personal motivations of military officers will vary.

Modern military dictatorship developed in Latin America during the 19th century, and it expanded in Europe during the early-20th century. It saw a resurgence during the Cold War, and new military dictatorships were established in Africa, Asia, and Latin America in the 1960s. Some scholars have asserted that the number of military dictatorships has declined since the end of the Cold War.

A government is the system or group of people governing an organized community, generally a state.

In the case of its broad associative definition, government normally consists of legislature, executive, and judiciary. Government is a means by which organizational policies are enforced, as well as a mechanism for determining policy. In many countries, the government has a kind of constitution, a statement of its governing principles and philosophy.

Militarism is the belief or the desire of a government or a people that a state should maintain a strong military capability and to use it aggressively to expand national interests and/or values. It may also imply the glorification of the military and of the ideals of a professional military class and the "predominance of the armed forces in the administration or policy of the state" (see also: stratocracy and military junta).

A military government is any government that is administered by a military, whether or not this government is legal under the laws of the jurisdiction at issue or by an occupying power. It is usually administered by military personnel.

A parliamentary system, or parliamentary democracy, is a form of government based on the fusion of powers. In this system the head of government (chief executive) derives their democratic legitimacy from their ability to command the support ("confidence") of a majority of the parliament, to which they are held accountable. This head of government is usually, but not always, distinct from a ceremonial head of state. This is in contrast to a presidential system, which features a president who is not fully accountable to the legislature, and cannot be replaced by a simple majority vote.

Countries with parliamentary systems may be constitutional monarchies, where a monarch is the head of state while the head of government is almost always a member of parliament, or parliamentary republics, where a mostly ceremonial president is the head of state while the head of government is from the legislature. In a few countries, the head of government is also head of state but is elected by the legislature. In bicameral parliaments, the head of government is generally, though not always, a member of the lower house.

A parliamentary republic is a republic that operates under a parliamentary system of government where the executive branch (the government) derives its legitimacy from and is accountable to the legislature (the parliament). There are a number of variations of parliamentary republics. Most have a clear differentiation between the head of government and the head of state, with the head of government holding real power and the head of state being a ceremonial position, similar to constitutional monarchies. In some countries the head of state has reserve powers to use at their discretion as a non-partisan "referee" of the political process. Some have combined the roles of head of state and head of government, much like presidential systems, but with a dependency upon parliamentary confidence. In general, parliamentary republics grant the highest sovereign powers to the parliament.

A parliamentary republic with an executive presidency, is a form of parliamentary democracy in which the executive derives its democratic legitimacy from its ability to command the confidence of the legislature to which it is held accountable, but is characterized by a combined head of state–head of government in the form of an executive president who carries out both functions. This is in contrast to conventional parliamentary systems (be it in a monarchy or a republic) where the executive is separate from the head of state, and a presidential system where the executive is separate from the legislature. The president is typically elected by the legislature and must maintain its confidence to remain in office, for which purpose they may be required to hold a seat.

This method of presidential election is distinct from an assembly-independent republic, in which either the combined head of state and government (as in the Federated States of Micronesia) or the directorial executive (as in Switzerland) are elected by the legislature but are not accountable to it. It is also distinct from the semi-presidential system (in particular, the 'president-parliamentary' variant), in which the president as head of state is independent of the legislature, while the head of government is subject to parliamentary confidence.
