The word government derives from the Greek verb meaning to steer with a gubernaculum, or rudder, a metaphorical sense attested in the literature of classical antiquity including Plato's Ship of State. This ancient nautical metaphor reveals that the concept of governing was originally understood as the act of steering a community through turbulent waters, a role that has persisted for five thousand years since the first small city-states appeared. The moment and place that the phenomenon of human government developed is lost in time, yet history records the formations of early governments in Sumer, ancient Egypt, the Indus Valley civilization, and the Yellow River civilization by the third to second millenniums BC. One reason that explains the emergence of governments includes agriculture, as the Neolithic Revolution enabled people to specialize in non-agricultural activities, allowing some to rule over others as an external authority. These early governments gradually became more complex as agriculture supported larger and denser populations, creating new interactions and social pressures that the government needed to control. Another explanation includes the need to properly manage infrastructure projects such as water infrastructure, which historically required centralized administration and complex social organization, as seen in regions like Mesopotamia. However, there is archaeological evidence that shows similar successes with more egalitarian and decentralized complex societies, suggesting that the path to governance was not a single linear progression but a diverse array of human responses to survival challenges.
The Five Regimes of Plato
Plato in his book The Republic divided governments into five basic types, four being existing forms and one being Plato's ideal form which exists only in speech. Aristocracy is rule by law and order, like ideal traditional benevolent kingdoms that are not tyrannical, while timocracy is rule by honor and duty, like a benevolent military with Sparta as an example. Oligarchy is rule by wealth and market-based ethics, like a laissez-faire capitalist state, and democracy is rule by pure liberty and equality, like a free citizen. Tyranny is rule by fear, like a despot, and these five regimes progressively degenerate starting with aristocracy at the top and tyranny at the bottom. In his Politics, Aristotle elaborates on Plato's five regimes discussing them in relation to the government of one, of the few, and of the many. From this follows the classification of forms of government according to which people have the authority to rule, either one person such as an autocracy like monarchy, a select group of people such as an aristocracy, or the people as a whole such as a democracy like a republic. Thomas Hobbes stated on their classification that the nature of power is the central question, and the two main forms being electoral contest and hereditary succession remain the primary ways political power is obtained to this day. These ancient classifications are not always mutually exclusive, and mixed governments are common, creating a complex tapestry of political systems that have evolved over millennia.
Starting at the end of the 17th century, the prevalence of republican forms of government grew, driven by the English Civil War and Glorious Revolution in England, the American Revolution, and the French Revolution which contributed to the growth of representative forms of government. The Soviet Union was the first large country to have a Communist government, marking a radical departure from previous systems, and since the fall of the Berlin Wall, liberal democracy has become an even more prevalent form of government. In the nineteenth and twentieth centuries, there was a significant increase in the size and scale of government at the national level, including the regulation of corporations and the development of the welfare state. A republic is a form of government in which the country is considered a public matter, not the private concern or property of the rulers, and where offices of states are subsequently directly or indirectly elected or appointed rather than inherited. Montesquieu included both democracies, where all the people have a share in rule, and aristocracies or oligarchies, where only some of the people rule, as republican forms of government. Other terms used to describe different republics include democratic republic, parliamentary republic, semi-presidential republic, presidential republic, federal republic, people's republic, and Islamic republic, each representing a unique adaptation of the core republican ideal to local cultural and historical contexts.
The Architecture of Power
Governments are typically organized into distinct institutions constituting branches of government each with particular powers, functions, duties, and responsibilities. The distribution of powers between these institutions differs between governments, as do the functions and number of branches. An independent, parallel distribution of powers between branches of government is the separation of powers, a model often called the trias politica model. However, in parliamentary and semi-presidential systems, branches of government often intersect, having shared membership and overlapping functions. Many governments have fewer or additional branches, such as an independent electoral commission or auditory branch, creating a complex web of checks and balances. Autocracy is a system of government in which supreme power is concentrated in the hands of one person, whose decisions are subject to neither external legal restraints nor regularized mechanisms of popular control except perhaps for the implicit threat of a coup d'état or mass insurrection. Absolute monarchy is a historically prevalent form of autocracy, wherein a monarch governs as a singular sovereign with no limitation on royal prerogative, and most absolute monarchies are hereditary, however some, notably the Holy See, are elected by an electoral college such as the college of cardinals or prince-electors. Other forms of autocracy include tyranny, despotism, and dictatorship, each representing a different manifestation of concentrated power.
The Gray Zones of Politics
Identifying a form of government can be challenging because many political systems originate from socio-economic movements, and the parties that carry those movements into power often name themselves after those ideologies. These parties may have competing political ideologies and strong ties to particular forms of government, and as a result, the movements themselves can sometimes be mistakenly considered as forms of government, rather than the ideologies that influence the governing system. Voltaire argued that the Holy Roman Empire is neither Holy, nor Roman, nor an Empire, highlighting the discrepancy between official de jure or ideal form and self-identification. In practice, the Soviet Union was a centralized autocratic one-party state under Joseph Stalin, despite its socialist republic label. Other complications include general non-consensus or deliberate distortion or bias of reasonable technical definitions of political ideologies and associated forms of governing, due to the nature of politics in the modern era. For example, the meaning of conservatism in the United States has little in common with the way the word's definition is used elsewhere, and what Americans now call conservatism much of the world calls liberalism or neoliberalism. A conservative in Finland would be labeled a socialist in the United States, and since the 1950s, conservatism in the United States has been chiefly associated with right-wing politics and the Republican Party, yet during the era of segregation many Southern Democrats were conservatives and they played a key role in the conservative coalition that controlled Congress from 1937 to 1963.
The Public Sector and Services
Governmental property, state-owned enterprises, public services, civil servants and employees of the government together compose the public sector of the economy. In modern developed countries, public services often include courts, education, electricity, emergency services, environmental protection, health care, mail, military, policing, public buildings, public broadcasting, public libraries, public parks, public utilities, public transportation, social services, state school, telecommunications, transportation infrastructure, urban planning, waste management, and water supply network. In developing countries, public services tend to be much less well developed, and for example, water services might only be available to the wealthy middle class. For political reasons, the service is often subsidized, which reduces the finance potentially available for expansion to poorer communities. The United Nations Sustainable Development Goal 5 is a global initiative that aims to influence the provision of public services and infrastructure to marginalized demographics. The mid-twentieth century saw the rise of German sociologist Max Weber's theory of bureaucracy, bringing about a substantive interest in the theoretical aspects of public administration. Public policy can be considered the sum of a government's direct and indirect activities, including various aspects of life such as education, health care, employment, finance, economics, transportation, and all over elements of society, and public policy making can be characterized as a dynamic, complex, and interactive system through which public problems are identified and resolved through the creation of new policy or reform of existing policy.
The Global Democracy Index
Democracy is the most popular form of government, and more than half of the nations in the world are democracies, 97 of 167 as of 2021. However, the world is becoming more authoritarian with a quarter of the world's population under democratically backsliding governments, according to The Global State of Democracy 2021 by the International Institute for Democracy and Electoral Assistance. The quality of a government can be measured by Government effectiveness index, which relates to political efficacy and state capacity, and the Democracy Index by the Economist Intelligence Unit, 2017, categorizes countries into Full Democracies, Flawed Democracies, Hybrid Regimes, and Authoritarian Regimes. Opinions vary by individuals concerning the types and properties of governments that exist, and shades of gray are commonplace in any government and its corresponding classification. Even the most liberal democracies limit rival political activity to one extent or another while the most tyrannical dictatorships must organize a broad base of support thereby creating difficulties for pigeonholing governments into narrow categories. Examples include the claims of the United States as being a plutocracy rather than a democracy since some American voters believe elections are being manipulated by wealthy Super PACs, and some consider that government is to be reconceptualized where in times of climatic change the needs and desires of the individual are reshaped to generate sufficiency for all, as discussed in Governing the Enough in a Warming World The Discourse of Sufficiency from a Climate Governmentality Perspective by Michel Deflorian in 2015.
