What is a system of government where one person rules with unlimited power and authority?

An autocracy is a form of government in which one ruler has absolute control and decision-making power. Autocracies have existed since ancient times, when kings and emperors ruled over great countries and tribal lands, and they exist today in the form of absolute monarchies and dictatorships. Unlike in a democracy, the people living in countries with autocratic governments have no say in determining the nation’s laws, or in how those laws are enforced. An autocratic ruler is accountable to no one; there is no system of checks and balances, no constitutional limit on the ruler’s power, and the ruler is not held accountable by a cabinet of advisors, a system of courts, the people, or the press.

In autocratic governments, the power of the ruler is absolute; dissent is not tolerated. For this reason, scholars have often linked autocracy with totalitarian regimes, such as that of Adolf Hitler in Germany and Josef Stalin in the Soviet Union. Autocracy is a general concept rather than a specific form of government. Though autocratic rulers have complete power over the people of their countries, their methods of governing can be vastly different.

Absolute monarchies and dictatorships still exist in modern times. Today’s kings and queens, as in ancient times, often rule by right of succession. Their royal lineage can be traced back to ancient times when their royal ancestors ruled by divine right—as it was widely believed that they descended from the gods. Dictators are absolute rulers who acquire their power rather than inherit it. Most commonly, dictators gain power as a result of revolution—typically, when a group of rebels rise up in protest and overthrow the existing government. Then, the dictator assumes control with the goal of establishing a new order. Dictators, especially military dictators, acquire their power by force.

Throughout history, during times of political unrest, people have tended to accept the command of strong leaders who could take control of their countries. In fact, Niccolo Machiavelli, an Italian political philosopher from the 15th century, recommended autocracy as a temporary measure and as a means of restoring political order and ending dissent.

Here's a rundown of the various forms of government, with definitions provided by "The World Factbook." 

Absolute monarchy - a form of government where the monarch rules unhindered, i.e., without any laws, constitution or legally organized opposition.

Anarchy - a condition of lawlessness or political disorder brought about by the absence of governmental authority.

Authoritarian - a form of government in which state authority is imposed onto many aspects of citizens' lives.

Commonwealth - a nation, state or other political entity founded on law and united by a compact of the people for the common good.

Communist - a system of government in which the state plans and controls the economy and a single -- often authoritarian -- party holds power; state controls are imposed with the elimination of private ownership of property or capital while claiming to make progress toward a higher social order in which all goods are equally shared by the people (i.e., a classless society).

Confederacy (Confederation) - a union by compact or treaty between states, provinces or territories that creates a central government with limited powers; the constituent entities retain supreme authority over all matters except those delegated to the central government.

Constitutional - a government by or operating under an authoritative document (constitution) that sets forth the system of fundamental laws and principles that determines the nature, functions and limits of that government.

Constitutional democracy - a form of government in which the sovereign power of the people is spelled out in a governing constitution.

Constitutional monarchy - a system of government in which a monarch is guided by a constitution whereby his/her rights, duties, and responsibilities are spelled out in written law or by custom.

Democracy - a form of government in which the supreme power is retained by the people, but which is usually exercised indirectly through a system of representation and delegated authority periodically renewed.

Democratic republic - a state in which the supreme power rests in the body of citizens entitled to vote for officers and representatives responsible to them.

Dictatorship - a form of government in which a ruler or small clique wield absolute power (not restricted by a constitution or laws).

Ecclesiastical - a government administrated by a church.

Emirate - similar to a monarchy or sultanate, a government in which the supreme power is in the hands of an emir (the ruler of a Muslim state); the emir may be an absolute overlord or a sovereign with constitutionally limited authority.

Federal (Federation) - a form of government in which sovereign power is formally divided -- usually by means of a constitution -- between a central authority and a number of constituent regions (states, colonies or provinces) so that each region retains some management of its internal affairs; differs from a confederacy in that the central government exerts influence directly upon both individuals as well as upon the regional units.

Federal republic - a state in which the powers of the central government are restricted and in which the component parts (states, colonies, or provinces) retain a degree of self-government; ultimate sovereign power rests with the voters who chose their governmental representatives.

Islamic republic - a particular form of government adopted by some Muslim states; although such a state is, in theory, a theocracy, it remains a republic, but its laws are required to be compatible with the laws of Islam.

Maoism - the theory and practice of Marxism-Leninism developed in China by Mao Zedong (Mao Tse-tung), which states that a continuous revolution is necessary if the leaders of a communist state are to keep in touch with the people.

Marxism - the political, economic and social principles espoused by 19th century economist Karl Marx; he viewed the struggle of workers as a progression of historical forces that would proceed from a class struggle of the proletariat (workers) exploited by capitalists (business owners), to a socialist "dictatorship of the proletariat," to, finally, a classless society -- Communism.

Marxism-Leninism - an expanded form of communism developed by Vladimir Lenin from doctrines of Karl Marx; Lenin saw imperialism as the final stage of capitalism and shifted the focus of workers' struggle from developed to underdeveloped countries.

Monarchy - a government in which the supreme power is lodged in the hands of a monarch who reigns over a state or territory, usually for life and by hereditary right; the monarch may be either a sole absolute ruler or a sovereign - such as a king, queen or prince - with constitutionally limited authority.

Oligarchy - a government in which control is exercised by a small group of individuals whose authority generally is based on wealth or power.

Parliamentary democracy - a political system in which the legislature (parliament) selects the government - a prime minister, premier or chancellor along with the cabinet ministers - according to party strength as expressed in elections; by this system, the government acquires a dual responsibility: to the people as well as to the parliament.

Parliamentary government (Cabinet-Parliamentary government) - a government in which members of an executive branch (the cabinet and its leader - a prime minister, premier or chancellor) are nominated to their positions by a legislature or parliament, and are directly responsible to it; this type of government can be dissolved at will by the parliament (legislature) by means of a no-confidence vote or the leader of the cabinet may dissolve the parliament if it can no longer function.

Parliamentary monarchy - a state headed by a monarch who is not actively involved in policy formation or implementation (i.e., the exercise of sovereign powers by a monarch in a ceremonial capacity); true governmental leadership is carried out by a cabinet and its head - a prime minister, premier or chancellor - who are drawn from a legislature (parliament).

Presidential - a system of government where the executive branch exists separately from a legislature (to which it is generally not accountable).

Republic - a representative democracy in which the people's elected deputies (representatives), not the people themselves, vote on legislation.

Socialism - a government in which the means of planning, producing and distributing goods is controlled by a central government that theoretically seeks a more just and equitable distribution of property and labor; in actuality, most socialist governments have ended up being no more than dictatorships over workers by a ruling elite.

Sultanate - similar to a monarchy, a government in which the supreme power is in the hands of a sultan (the head of a Muslim state); the sultan may be an absolute ruler or a sovereign with constitutionally limited authority.

Theocracy - a form of government in which a Deity is recognized as the supreme civil ruler, the Deity's laws are interpreted by ecclesiastical authorities (bishops, mullahs, etc.); a government subject to religious authority.

Totalitarian - a government that seeks to subordinate the individual to the state by controlling not only all political and economic matters, but also the attitudes, values and beliefs of its population.
