Democracy refers to a form of government in which the people either have the authority to choose their governing legislators, or the authority to decide on legislation. Who is considered part of the people and how authority is shared among or delegated by the people has changed over time and at different speeds in different countries, but more and more of the inhabitants of countries have generally been included. Cornerstones of democracy include freedom of assembly and speech, inclusiveness and equality, membership, consent, voting, right to life and minority rights.

The Center for the Study of Democracy is a research and education institute at St. Mary's College of Maryland that focuses on the study of the history of emerging democracy in St. Mary's City, Maryland, the site of Maryland'a first colonial capital and the location of many firsts in the development of democratic rights in North America; this work is done in conjunction with studies of modern democracies.

Civic virtue is the harvesting of habits important for the success of the community. Closely linked to the concept of citizenship, civic virtue is often conceived as the dedication of citizens to the common welfare of their community even at the cost of their individual interests. The identification of the character traits that constitute civic virtue has been a major concern of political philosophy. The term civility refers to behavior between persons and groups that conforms to a social mode, as itself being a foundation of society and law.

Civil society can be understood as the "third sector" of society, distinct from government and business, and including the family and the private sphere. By other authors, civil society is used in the sense of 1) the aggregate of non-governmental organizations and institutions that manifest interests and will of citizens or 2) individuals and organizations in a society which are independent of the government.

The Community of Democracies (CoD) is an intergovernmental coalition of states established in 2000. Its aim is to bring together governments, civil society and the private sector in the pursuit of the common goal of supporting democratic rules, expand political participation, advance and protect democratic freedoms, and strengthening democratic norms and institutions around the world. The task of more democracy is outlined in the Warsaw Declaration. It is disputed if the CoD qualifies as an International Organization in the legal sense.
Consensus decision-making or consensus politics is group decision-making processes in which participants develop and decide on proposals with the aim, or requirement, of acceptance by all. The focus on establishing agreement of the supermajority and avoiding unproductive opinion, differentiates consensus from unanimity, which requires all participants to support a decision.

While Marxists propose replacing the bourgeois state with a proletarian semi-state through revolution, which would eventually wither away, anarchists warn that the state must be abolished along with capitalism. Nonetheless, the desired end results, a stateless, communal society, are the same.

The Democracy Index is an index compiled by the Economist Intelligence Unit (EIU), the research division of the Economist Group, a UK-based private company which publishes the weekly newspaper The Economist.

Democracy-Dictatorship (DD), index of democracy and dictatorship or simply the DD index or the DD datasets refers to the binary measure of democracy and dictatorship first proposed by Adam Przeworski et al. (2010), and further developed and maintained by Cheibub, Gandhi, and Vreeland (2009). Though the most recent data set is only updated for 2008, there is planning by Cheibub to update it to the present year.

Democratic backsliding, also known as autocratization and de-democratization, is a gradual decline in the quality of democracy and the opposite of democratization, which may result in the state losing its democratic qualities, becoming an autocracy or authoritarian regime. Democratic decline is caused by the state-led weakening of political institutions that sustain the democratic system, such as the peaceful transition of power or electoral systems. Although these political elements are assumed to lead to the onset of backsliding, other essential components of democracy such as infringement of individual rights and the freedom of expression question the health, efficiency and sustainability of democratic systems over time.

The question of whether the governance of the European Union (EU) lacks democratic legitimacy has been debated since the time of the European Economic Community in the late 1970s. This led in part to an elected European Parliament being created in 1979 and given the power to approve or reject EU legislation. Since then, usage of the term has broadened to describe newer issues facing the European Union. Voter turnout at Elections to the European Parliament fell consecutively at every election from the first in 1979 up to 2014, when it hit a low of 42.54% before finally rising in 2019. The 2014 turnout figure is lower than that of any national election in the 27 countries of the European Union, where turnout at national elections averages 68% across the EU.

In Marxist philosophy, the dictatorship of the proletariat is a state of affairs in which the proletariat holds political power. The dictatorship of the proletariat is the intermediate stage between a capitalist economy and a communist economy, whereby the post-revolutionary state seizes the means of production, compels the implementation of direct elections on behalf of and within the confines of the ruling proletarian state party, and instituting elected delegates into representative workers' councils that nationalise ownership of the means of production from private to collective ownership. During this phase, the administrative organizational structure of the party is to be largely determined by the need for it to govern firmly and wield state power to prevent counterrevolution and to facilitate the transition to a lasting communist society. Other terms commonly used to describe the dictatorship of the proletariat include socialist state, proletarian state, democratic proletarian state, revolutionary dictatorship of the proletariat and democratic dictatorship of the proletariat.

Two central issues for democracies are the right to candidate, and suffrage or the franchise—that is, the decision as to who is entitled to vote. For example, Athenian democracy limited the vote to male citizens, while slaves, foreigners, and women of any status were excluded. Requirements and exclusions such as these, along with racial prohibitions, have been common in democracies. The definition of legal personhood has been historically tied up with these questions.

The End of History and the Last Man (1992) is a book of political philosophy by American political scientist Francis Fukuyama which argues that with the ascendancy of Western liberal democracy—which occurred after the Cold War (1945–1991) and the dissolution of the Soviet Union (1991)—humanity has reached "not just ... the passing of a particular period of post-war history, but the end of history as such: That is, the end-point of mankind's ideological evolution and the universalization of Western liberal democracy as the final form of human government." For the book, which is an expansion of his essay, "The End of History?" (1989), Fukuyama draws upon the philosophies and ideologies of Georg Wilhelm Friedrich Hegel and Karl Marx, who define human history as a linear progression, from one socioeconomic epoch to another.

Gödel's Loophole is an "inner contradiction" in the Constitution of the United States which Austrian-German-American logician, mathematician, and analytic philosopher Kurt Gödel claimed to have discovered in 1947. The flaw would have allowed the American democracy to be legally turned into a dictatorship. Gödel told his friend Oskar Morgenstern about the existence of the flaw and Morgenstern told Albert Einstein about it at the time, but Morgenstern, in his recollection of the incident in 1971, never mentioned the exact problem as Gödel saw it. This has led to speculation about the precise nature of what has come to be called "Gödel's Loophole". It has been called "one of the great unsolved problems of constitutional law."

The Iron Front was a German paramilitary organization in the Weimar Republic which consisted of social democrats, trade unionists, and liberals. Its main goal was to defend liberal democracy against totalitarian ideologies on the far right and far left. The Iron Front chiefly opposed the Sturmabteilung (SA) wing of the Nazi Party and the Antifaschistische Aktion wing of the Communist Party of Germany. Formally independent, it was intimately associated with the Social Democratic Party of Germany (SPD). The Three Arrows, originally designed for the Iron Front, became a well-known social democratic symbol representing resistance against monarchism, Nazism, and communism during the parliamentary elections in November 1932. The Three Arrows were later adopted by the SPD itself.

Liberal democracy, also referred to as Western democracy, is a political ideology and a form of government in which representative democracy operates under the principles of liberalism. It is characterised by elections between 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, and the equal protection of human rights, civil rights, civil liberties and political freedoms for all people. 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. After a period of expansion in the second half of the 20th century, liberal democracy became a prevalent political system in the world.

Monitory democracy is a phase of democracy characterised by instruments of public monitoring and scrutinising of government power. It began following the events of the Second World War. The theory was coined by Australian Professor John Keane.

The democratic peace theory posits that democracies are hesitant to engage in armed conflict with other identified democracies. Among proponents of the democratic peace theory, several factors are held as motivating peace between democratic states:Democratic leaders are forced to accept responsibility for war losses to a voting public; Publicly accountable statespeople are inclined to establish diplomatic institutions for resolving international tensions; Democracies are not inclined to view countries with adjacent policy and governing doctrine as hostile; Publicly accountable democracies require justification to start a conflict and are thus slow to mobilise, minimising the risk of a surprise aggressive attack; Democracies tend to possess greater public wealth than other states, and therefore eschew war to preserve infrastructure and resources.

A peaceful transition or transfer of power is a concept important to democratic governments in which the leadership of a government peacefully hands over control of government to a newly-elected leadership. This may be after elections or during the transition from a different kind of political regime, such as the postcommunist period after the fall of the Soviet Union, or the elections in Libya following the fall of Muammar Gaddafi.

The term post-democracy was used by Warwick University political scientist Colin Crouch in 2000 in his book Coping with Post-Democracy. It designates states that operate by democratic systems, but whose application is progressively limited. A small elite is taking the tough decisions and co-opts the democratic institutions. Crouch further developed the idea in an article called Is there a liberalism beyond social democracy? for the think tank Policy Network and in his subsequent book The Strange Non-Death of Neo-Liberalism.

The Potsdam Declaration, or the Proclamation Defining Terms for Japanese Surrender, was a statement that called for the surrender of all Japanese armed forces during World War II.

The public sphere is an area in social life where individuals can come together to freely discuss and identify societal problems, and through that discussion influence political action. Such a discussion is called public debate and is defined as the expression of views on matters that are of concern to the public—often, but not always, with opposing or diverging views being expressed by participants in the discussion. Public debate takes place mostly through the mass media, but also at meetings or through social media, academic publications and government policy documents. The term was originally coined by German philosopher Jürgen Habermas who defined the public sphere as "made up of private people gathered together as a public and articulating the needs of society with the state". Communication scholar Gerard A. Hauser defines it as "a discursive space in which individuals and groups associate to discuss matters of mutual interest and, where possible, to reach a common judgment about them". The public sphere can be seen as "a theater in modern societies in which political participation is enacted through the medium of talk" and "a realm of social life in which public opinion can be formed".

Synoecism or synecism, also spelled synoikism, was originally the amalgamation of villages in Ancient Greece into poleis, or city-states. Etymologically the word means "dwelling together (syn) in the same house (oikos)." Subsequently, any act of civic union between polities of any size was described by the word synoikismos. The closest analogy today is the incorporation of a city; in fact, "incorporation" is often used to translate synoikismos, in addition to the Latinized synoecism. Synoecism is opposed to Greek dioecism, the creation of independent communities within the territory of a polis.

Virtual representation was the idea that the members of Parliament, including the Lords and the Crown-in-Parliament, reserved the right to speak for the interests of all British subjects, rather than for the interests of only the district that elected them or for the regions in which they held peerages and spiritual sway. Virtual representation was the British response to the First Continental Congress in the American colonies. The Second Continental Congress asked for representation in Parliament in the Suffolk Resolves, also known as the first Olive Branch Petition. Parliament claimed that their members had the well being of the colonists in mind. The Colonies rejected this premise.
