Private property in the context of Public property

Political philosophy studies the theoretical and conceptual foundations of politics. It examines the nature, scope, and legitimacy of political institutions, such as states. The field investigates different forms of government, ranging from democracy to authoritarianism, and the values guiding political action, like justice, equality, and liberty. As a normative field, political philosophy focuses on desirable norms and values, in contrast to political science, which emphasizes empirical description.

Political ideologies are systems of ideas and principles that outline how society should work. Anarchism rejects the coercive power of centralized governments. It proposes a stateless society to promote liberty and equality. Conservatism seeks to preserve traditional institutions and practices. It is skeptical of the human ability to radically reform society, arguing that drastic changes can destroy the wisdom of past generations. Liberals advocate for individual rights and liberties, the rule of law, private property, and tolerance. They believe that governments should protect these values to enable individuals to pursue personal goals without external interference. Socialism emphasizes collective ownership and equal distribution of basic goods. It seeks to overcome sources of inequality, including private ownership of the means of production, class systems, and hereditary privileges. Other strands of political philosophy include environmentalism, realism, idealism, consequentialism, perfectionism, nationalism, individualism, and communitarianism.

Classical republicanism, also known as civic republicanism or civic humanism, is a form of republicanism developed in the Renaissance inspired by the governmental forms and writings of classical antiquity, especially such classical writers as Aristotle, Polybius, and Cicero. Classical republicanism is built around concepts such as liberty as non-domination, self-government, rule of law, property-based personality, anti-corruption, abolition of monarchy, civics, civil society, common good, civic virtue, civic participation, popular sovereignty, patriotism and mixed government.

State ownership, also called public ownership or government ownership, is the ownership of an industry, asset, property, or enterprise by the national government of a country or state, or a public body representing a community, as opposed to an individual or private party. Public ownership specifically refers to industries selling goods and services to consumers and differs from public goods and government services financed out of a government's general budget. Public ownership can take place at the national, regional, local, or municipal levels of government; or can refer to non-governmental public ownership vested in autonomous public enterprises. Public ownership is one of the three major forms of property ownership, differentiated from private, collective/cooperative, and common ownership.

In market-based economies, state-owned assets are often managed and operated as joint-stock corporations with a government owning all or a controlling stake of the company's shares. This form is often referred to as a state-owned enterprise. A state-owned enterprise might variously operate as a Nonprofit corporation, as it may not be required to generate a profit; as a commercial enterprise in competitive sectors; or as a natural monopoly. Governments may also use the profitable entities they own to support the general budget. The creation of a state-owned enterprise from other forms of public property is called corporatization.

The police are a constituted body of people empowered by a state with the aim of enforcing the law and protecting the public order as well as the public itself. This commonly includes ensuring the safety, health, and possessions of citizens, and to prevent crime and civil disorder. Their lawful powers encompass arrest and the use of force legitimized by the state via the monopoly on violence. The term is most commonly associated with the police forces of a sovereign state that are authorized to exercise the police power of that state within a defined legal or territorial area of responsibility. Police forces are often defined as being separate from the military and other organizations involved in the defense of the state against foreign aggressors; however, gendarmerie are military units charged with civil policing. Police forces are usually public sector services, funded through taxes.

Law enforcement is only part of policing activity. Policing has included an array of activities in different situations, but the predominant ones are concerned with the preservation of order. In some societies, in the late 18th and early 19th centuries, these developed within the context of maintaining the class system and the protection of private property. Police forces have become ubiquitous and a necessity in complex modern societies. However, their role can sometimes be controversial, as they may be involved to varying degrees in corruption, brutality, and the enforcement of authoritarian rule.

Jean-Jacques Rousseau (UK: /ˈruːsoʊ/, US: /ruːˈsoʊ/; French: [ʒɑ̃ʒak ʁuso]; 28 June 1712 – 2 July 1778) was a Genevan philosopher, philosophe, writer, and composer. His political philosophy influenced the progress of the Age of Enlightenment throughout Europe, as well as aspects of the French Revolution and the development of modern political, economic, and educational thought.

Rousseau's Discourse on Inequality, which argues that private property is the source of inequality, and The Social Contract, which outlines the basis for a legitimate political order, are cornerstones in modern political and social thought. Rousseau's sentimental novel Julie, or the New Heloise (1761) was important to the development of preromanticism and romanticism in fiction. His Émile, or On Education (1762) is an educational treatise on the place of the individual in society. Rousseau's autobiographical writings—the posthumously published Confessions (completed in 1770), which initiated the modern autobiography, and the unfinished Reveries of the Solitary Walker (composed 1776–1778)—exemplified the late 18th-century "Age of Sensibility", and featured an increased focus on subjectivity and introspection that later characterized modern writing.

Liberalism is a political and moral philosophy based on the rights of the individual, liberty, consent of the governed, political equality, right to private property, and equality before the law. Liberals espouse various and sometimes conflicting views depending on their understanding of these principles but generally support private property, market economies, individual rights (including civil rights and human rights), liberal democracy, secularism, rule of law, economic and political freedom, freedom of speech, freedom of the press, freedom of assembly, and freedom of religion. Liberalism is frequently cited as the dominant ideology of modern history.

Liberalism became a distinct movement in the Age of Enlightenment, gaining popularity among Western philosophers and economists. Liberalism sought to replace the norms of hereditary privilege, state religion, absolute monarchy, the divine right of kings and traditional conservatism with representative democracy, rule of law, and equality under the law. Liberals also ended mercantilist policies, royal monopolies, and other trade barriers, instead promoting free trade and marketization. The philosopher John Locke is often credited with founding liberalism as a distinct tradition based on the social contract, arguing that each man has a natural right to life, liberty and property, and governments must not violate these rights. While the British liberal tradition emphasized expanding democracy, French liberalism emphasized rejecting authoritarianism and is linked to nation-building.

The Political Constitution of the Mexican Republic of 1857 (Spanish: Constitución Política de la República Mexicana de 1857), often called simply the Constitution of 1857, was the liberal constitution promulgated in 1857 by Constituent Congress of Mexico during the presidency of Ignacio Comonfort. Ratified on February 5, 1857, the constitution established individual rights, including universal male suffrage, and others such as freedom of speech, freedom of conscience, freedom of the press, freedom of assembly, and the right to bear arms. It also reaffirmed the abolition of slavery, debtors' prisons, and all forms of cruel and unusual punishment such as the death penalty. The constitution was designed to guarantee a limited central government by federalism and created a strong national congress, an independent judiciary, and a small executive to prevent a dictatorship. Liberal ideals meant the constitution emphasized private property of individuals and sought to abolish common ownership by corporate entities, mainly the Catholic Church and indigenous communities, incorporating the legal thrust of the Lerdo Law into the constitution.

A number of articles were contrary to the traditional powers of the Catholic Church, such as the ending of Catholicism as official religion, the nationwide establishment of secular public education, the removal of institutional fueros (legal privileges), and the forced sale of Church property. Conservatives strongly opposed the enactment of the constitution, which polarized Mexican society. The Reform War (1858-1860) began as a result, with liberals winning on the battlefield over conservatives. The losing conservatives sought another way back into power, and their politicians invited Maximilian I of Mexico, a Habsburg, to establish a Mexican monarchy with the Church's support. The republican government-in-domestic-exile was headed by President Benito Juárez as the legitimate Mexican government under the constitution. With the ouster of the French and the defeat of the conservatives in 1867, the Restored Republic was again governed under the 1857 Constitution. The constitution was durable but its provisions not always followed in practice. It was revised in 1874 to create a Senate. It remained as Mexico's constitution until 1917 although many of its provisions ceased to be enforced.

Capitalism is an economic system based on the private ownership of the means of production and their use for the purpose of obtaining profit. This socioeconomic system has developed historically through several stages and is defined by a number of basic constituent elements: private property, profit motive, capital accumulation, competitive markets, commodification, wage labor, and an emphasis on innovation and economic growth. Capitalist economies tend to experience business cycles of economic growth followed by recessions.

Economists, historians, political economists, and sociologists have adopted different perspectives in their analyses of capitalism and have recognized various forms of it in practice. These include laissez-faire or free-market capitalism, state capitalism, and welfare capitalism. Different forms of capitalism feature varying degrees of free markets, public ownership, obstacles to free competition, and state-sanctioned social policies. The degree of competition in markets and the role of intervention and regulation, as well as the scope of state ownership, vary across different models of capitalism. The extent to which different markets are free and the rules defining private property are matters of politics and policy. Most of the existing capitalist economies are mixed economies that combine elements of free markets with state intervention and in some cases economic planning.

Liberal democracy, also called Western-style democracy, or substantive democracy, is a form of government that combines the organization of a democracy with ideas of liberal political philosophy. Common elements within a liberal democracy are: elections between or among multiple distinct political parties; a separation of powers into different branches of government; the rule of law in everyday life as part of an open society; a market economy with private property; universal suffrage; and the equal protection of human rights, civil rights, civil liberties, and political freedoms for all citizens. Substantive democracy refers to substantive rights and substantive laws, which can include substantive equality, the equality of outcome for subgroups in society. Liberal democracy emphasizes the separation of powers, an independent judiciary, and a system of checks and balances between branches of government. Multi-party systems with at least two persistent, viable political parties are characteristic of liberal democracies.

Governmental authority is legitimately exercised only in accordance with written, publicly disclosed laws adopted and enforced in accordance with established procedure. To define the system in practice, liberal democracies often draw upon a constitution, either codified or uncodified, to delineate the powers of government and enshrine the social contract. A liberal democracy may take various and mixed constitutional forms: it may be a constitutional monarchy or a republic. It may have a parliamentary system, presidential system, or semi-presidential system. Liberal democracies are contrasted with illiberal democracies and dictatorships. Some liberal democracies, especially those with large populations, use federalism (also known as vertical separation of powers) in order to prevent abuse and increase public input by dividing governing powers between municipal, provincial and national governments. The characteristics of liberal democracies are correlated with increased political stability, lower corruption, better management of resources, and better health indicators such as life expectancy and infant mortality.

Property is a system of rights that gives people legal control of valuable things, and also refers to the valuable things themselves. Depending on the nature of the property, an owner of property may have the right to consume, alter, share, rent, sell, exchange, transfer, give away, or destroy it, or to exclude others from doing these things, as well as to perhaps abandon it; whereas regardless of the nature of the property, the owner thereof has the right to properly use it under the granted property rights.

In economics and political economy, there are three broad forms of property: private property, public property, and collective property (or cooperative property). Property may be jointly owned by more than one party equally or unequally, or according to simple or complex agreements; to distinguish ownership and easement from rent, there is an expectation that each party's will with regard to the property be clearly defined and unconditional.. The parties may expect their wills to be unanimous, or alternatively each may expect their own will to be sufficient when no opportunity for dispute exists.

Istanbul Airport (IATA: IST, ICAO: LTFM) is the larger of two international airports serving Istanbul, Turkey. It is located in the Arnavutköy district on the European side of the city. It is the largest airport in Turkey, the largest privately-owned airport in the world, and the second busiest airport in Europe.

All scheduled commercial passenger flights were transferred from Atatürk Airport to Istanbul Airport on 6 April 2019, following the closure of Atatürk Airport for scheduled passenger flights. The IATA airport code IST was also transferred to the new airport.

The right to property, or the right to own property (cf. ownership), is often classified as a human right for natural persons regarding their private property. The Fourth Amendment to the United States Constitution is credited as a significant precedent for the legal protection of individual property rights.

A right to property is specified in Article 17 of the 1948 Universal Declaration of Human Rights, but it is not recognised in the 1966 International Covenant on Civil and Political Rights or in the 1966 International Covenant on Economic, Social and Cultural Rights. The 1950 European Convention on Human Rights acknowledges a right for a natural or legal person to "peaceful enjoyment of his possessions", subject to the "general interest or to secure the payment of taxes."

The proletariat (/ˌproʊlɪˈtɛəriət/; from Latin proletarius 'producing offspring') is the social class of wage-earners, those members of a society whose possession of significant economic value is their labour power (their capacity to work). A member of such a class is a proletarian or a proletaire. Marxist philosophy regards the proletariat under conditions of capitalism as an exploited class,⁠ deprived of their own means of production and thereby forced to operate industrial means of production held as private property by the bourgeoisie, receiving wages which represent less than the value their labour produced, the remainder appropriated by the bourgeoisie as profits.

Karl Marx argued that the conflicting inherent interests between the proletariat and the bourgeoisie gives the proletariat common economic and political interests that transcend national boundaries, impelling them to unite and assert their sovereignty over the capitalist class, and eventually to create a socialist society free from class distinctions.

Alice O'Connor (born Alisa Zinovyevna Rosenbaum; February 2 [O.S. January 20], 1905 – March 6, 1982), better known by her pen name Ayn Rand (/aɪn/ ), was a Russian-born American writer and philosopher. She is known for her fiction and for developing a philosophical system which she named Objectivism. Born and educated in Russia, she moved to the United States in 1926. After two early novels that were initially unsuccessful and two Broadway plays, Rand achieved fame with her 1943 novel The Fountainhead. In 1957, she published her best-selling work, the novel Atlas Shrugged. Afterward, until her death in 1982, she turned to non-fiction to promote her philosophy, publishing her own periodicals and releasing several collections of essays.

Rand advocated reason and rejected faith and religion. She supported rational and ethical egoism as opposed to altruism and hedonism. In politics, she condemned the initiation of force as immoral and supported laissez-faire capitalism, which she defined as the system based on recognizing individual rights, including private property rights. Although she opposed libertarianism, which she viewed as anarchism, Rand is often associated with the modern libertarian movement in the United States. In art, she promoted romantic realism. She was sharply critical of most philosophers and philosophical traditions known to her, with a few exceptions.
