Words worth knowing
Politics runs on words until they mean nothing. This page fixes the meanings: what each term describes, where it came from, and what it does not mean. Every entry carries its own source, so you can check the definition instead of taking it on trust. The documented histories of Israel and Palestine and of Putin's Russia live on their own History page, linked from the war map they explain.
A definition is not an argument. These entries tell you what a word means so the argument can be had honestly, and they do not settle whether a movement or a government is good or bad. Where a claim is genuinely contested, the entry says so.
The sources here are reference works, governments and human rights organizations, not opinion columns. Spotted an error, or want a term added? Use the contact link at the bottom of any page.
Fascism
An ultranationalist politics that rejects democracy, liberalism and equality, concentrates power in one leader or one party, and sells the nation as a people reborn through purification and force. Mussolini's Italy is the original. Hitler's Germany is the most lethal example.
What historians look for: a story of national decline followed by rebirth, a leader who stands above the law, uniformed fighters in the street, a rotating list of internal enemies blamed for the decline (Jews, migrants, communists, unions, the press, queer people), and open contempt for elections and courts as obstacles. Not every authoritarian is a fascist, and not every policy anyone dislikes is fascism. The word names this specific package, and using it for everything is how it stops meaning anything.

Nazism
The ideology and the one-party rule of the Nazi Party in Germany from 1933 to 1945, built on racial hierarchy: a supposed Aryan master race at the top, Jews cast as a racial enemy to be removed. Antisemitism was not a side policy, it was the core. The Nuremberg Laws of 1935 stripped Jews of citizenship, then came ghettos and confiscation, then the murder of six million Jews in the Holocaust, alongside Roma, disabled people, Slavic civilians, political prisoners and gay men.
Nazism is a specific case of fascism, not a synonym for it and not unrelated to it either. Fascism is the wider family: ultranationalism, one leader, contempt for democracy. Nazism is that family's racial theory taken to genocide, plus a war of conquest in Eastern Europe built on the idea of living space.

The far right and the alt-right
The far right is the part of the spectrum that rejects liberal democracy, equal citizenship and pluralism, and wants society arranged by hierarchy: race, religion, nation or tradition. It includes fascist and neo-Nazi groups, white nationalists, armed paramilitaries and religious extremists, and also the radical right that stands in elections while still refusing those basics.
The alt-right is the American packaging of white nationalism for the internet age, popularized between roughly 2010 and 2016: memes, irony, identitarian language, and the claim to be beyond conservatism and beyond liberalism. It rebrands what it descends from. A right-wing voter is not automatically far right. The line is where democracy and equal citizenship get rejected.
White nationalism and white supremacy
White supremacy is the claim that white people are superior and should dominate society. Its record is slavery and Jim Crow in the United States, colonial rule across Africa and Asia, apartheid South Africa, and the Nazi state.
White nationalism is the politics that follows from it: white people are a nation and need their own state or territory, separated from everyone else. Ethnostate proposals, Klan separatism and the accelerationist groups that want a race war all sit in this family. Both terms rest on one core claim: race decides a person's worth and a person's belonging.
Antisemitism
Hostility or prejudice against Jews as Jews, whether they are treated as a religion, an ethnicity, or both. Its history runs from medieval expulsions and blood libels through nineteenth century racial science and the Dreyfus affair to the Holocaust. Today it shows up as Holocaust denial, attacks on synagogues, conspiracy theories about Jewish control of finance and the media, and abuse aimed at Jews for what Israel's government does.
The IHRA working definition, adopted by the United States, the European Union and dozens of other countries, describes it as a certain perception of Jews that may be expressed as hatred, with worked examples. It also states that criticism of Israel like that leveled at any other country is not antisemitic, while blaming Jews as a group for Israel's policy is. That line matters, because both sides of the argument over Israel reach for the charge.

Anti-fascism (Antifa)
Not an organization. There is no membership, no leadership, no dues and no spokesperson. Antifa is a loose tradition of direct action against far-right organizing: the position that fascism should be stopped in the street before it wins elections, rather than handed to the police and the courts to deal with once it already has.
It descends from the anti-fascist groups that fought the Nazis in Weimar Germany, including the Communist Party's Antifaschistische Aktion in 1932, and it revived in the 1980s against skinhead neo-Nazis and again in the United States after 2016. Tactics run from counter-protest and exposing violent organizers to, at the fringes, fighting and property destruction. Because it is a tendency rather than an institution, nobody joins it and nobody speaks for it.

Socialism
The tradition that wealth produced by workers should be owned socially and run democratically: by the workers themselves, by co-operatives, by communities, or by a state answerable to the public, instead of by private owners who keep the profit. It grew in industrial Europe in the early nineteenth century, when the factory made the gap between who does the work and who gets the money impossible to miss.
It splits into currents that are not interchangeable. Revolutionary socialism wants the system replaced. Democratic socialism works through elections and mixes public and co-operative ownership with private enterprise. Social democracy, the Nordic model, keeps capitalism and then taxes and regulates it hard. American politics calls any public program socialism. That is not what the word means in political science.
Communism
In theory, a classless and stateless society where the means of production are held in common and people contribute and take according to need. Marx and Engels put it into modern politics in The Communist Manifesto in 1848, as the end point of history's class struggles, reached by revolution in most of its strands.
In practice, every state that has called itself communist has been a one-party state ruled by a party claiming to act for the working class, usually with a command economy, no political pluralism and, in the worst cases, mass terror. Those governments claimed to be on the way to communism. Whether they ever got close is the argument historians actually have, and judging the theory only by them assumes the answer in advance.
Authoritarianism
A political system where power sits in one leader or a small group with almost no checks: elections that cannot remove them, courts that will not rule against them, press that cannot criticize them safely, opposition that gets punished. Most citizens keep their private lives, which is what separates it from totalitarianism, where the state also wants to control what you believe.
Most dictatorships today are authoritarian rather than totalitarian. They want obedience more than conviction, and they leave enough private life for the economy to keep running. The test that matters is simple: can the people at the top be removed without violence?
Totalitarianism
The stronger form of dictatorship: a state that does not only demand obedience but goes after belief itself, through one official ideology, one party, a secret police, a controlled press, and control of schools, unions, churches and family life. Nazi Germany and the Soviet Union under Stalin are the textbook cases, and the word was coined to describe them.
Totalitarianism and authoritarianism are not interchangeable. Authoritarian rulers want you quiet. Totalitarian rulers want you convinced. Almost nothing today is fully totalitarian, and the distinction matters because the two systems fail and get dismantled in different ways.
Oligarchy
Rule by a small group, whether they got there through wealth, family, military rank or party position. The term goes back to Aristotle. Robert Michels argued in 1911 that every organization, even democratic ones, ends up run by a leadership caste that starts wanting to keep its own position more than it wants the group's goals.
Modern cases are well documented: Russia after 2000, where a handful of industrialists, security officials and state firms orbit one leader; post-Soviet states built on captured industries; oil states where one family owns the resource. The test is whether that group can be voted out or prosecuted. If it cannot, it is an oligarchy.
Plutocracy
Rule by the wealthy. Stronger than the everyday observation that money buys influence: policy follows what the rich want regardless of what everybody else wants. The classic modern study of this, by Martin Gilens and Benjamin Page in 2014, tested 1,779 policy questions in the United States and found that economic elites and organized business groups had substantial independent influence over what the government did, while average citizens had little or none.
A country can be a democracy on paper and a plutocracy in practice. Those two descriptions are not opposites, and that is the whole point of having the word.

Kleptocracy
Rule by theft. The people in office treat the state as a looting machine: ministries and contracts sold, public budgets routed to family and friends, public money moved into personal and offshore accounts. Unlike ordinary corruption, the stealing is the reason to hold the power.
Documented examples include Nigeria under Sani Abacha, the Philippines under Ferdinand Marcos, and the offshore wealth revealed for Russian officials in the Panama and Pandora Papers leaks. Kleptocracy also travels. Stolen money needs banks, lawyers and property markets that do not ask where it came from.
Corporatocracy
A society run for the benefit of large corporations, where government policy is written with, and often by, the industries it is supposed to oversee: lobbying that writes the draft, the revolving door between regulators and the firms they regulate, campaign cash on both sides, and rules only a giant could afford to meet.
Do not confuse it with corporatism, the older political science term for organizing society into official bodies: employers' associations, unions and the state negotiating together, which Fascist Italy claimed as its model. One is rule by corporations, a concentration of power with no electorate behind it. The other is a structure of bargaining. They share a root and nothing else.

Regulatory capture
When the industry an agency is supposed to oversee ends up running the agency: the same firms help write the rules, staff the office through the revolving door, fund the studies, and hire the lawyers who argue the cases. The idea is old in economics. George Stigler argued in 1971 that regulation is usually sought by the regulated, because a concentrated industry can afford to lobby and diffuse consumers cannot.
The tell is not bribery. It is a public agency whose decisions consistently track the preferences of the companies it watches, in language only those companies had the staff to draft. Clean campaign finance does not fix it, because the payment arrives as careers, access and information rather than cash.

Surveillance capitalism
A business model that treats personal data as raw material: take more than the person offered, use it to predict what they will do next, then sell the prediction or use it to steer the behavior itself. The term was coined by the Harvard professor Shoshana Zuboff in 2019 for markets that trade in what she called human futures.
It is the logic behind a camera network that starts as a safety feature and ends as a permanent, searchable record of who went where: plate readers, facial recognition, the data exhaust of everyday apps. Collection for one purpose becomes sale, sharing and policing for another.

Coup and self-coup
A coup d'état is the sudden, illegal removal of a government by a small group, usually the military or the security services, without going through the constitution's own procedures. Elections, courts and legislatures are not consulted, because the point is that the usual routes get bypassed. Analysts have counted hundreds of attempts around the world since 1950, and coup governments rarely deliver what they promise.
A self-coup is when the people already in power do it to themselves: the president dissolves parliament, suspends the constitution and rules by decree, turning the state against its own rules. Fujimori in Peru in 1992 is the standard case, and self-coup attempts have kept appearing since. It is worth its own name because the uniforms stay home and it is still a coup.

Demagogue
A politician who wins support by appealing to fear, resentment and prejudice instead of to argument, and who treats the crowd's mood as the only authority there is. The word is older than today's troubles: Aristotle wrote about the type, and Athenian voters knew what one looked like.
The pattern is consistent: simple answers to complicated problems, a list of outsiders who are to blame, praise for the crowd as the real people and contempt for anything that checks the leader (courts, press, civil service), and flattery that turns to fury the moment the crowd stops applauding. Detailed policy is not part of the act.

Populism
A style of politics that claims to speak for a pure, hard working people against a rotten elite. It comes in left and right versions, and in democracies and dictatorships, which is why political scientists treat it as a strategy rather than an ideology: the move that matters is splitting society into the good people and a corrupt establishment.
It is not a synonym for fascism and not an insult by definition. A populist can be democrat or authoritarian, and some populist movements check power instead of grabbing it. The question to ask is what the leader wants to do with the institutions in the way: work with them, or break them.
Misinformation and disinformation
Misinformation is false or misleading content spread without intent to deceive: a wrong figure passed along in good faith. Disinformation is the same content spread on purpose, to profit, to discredit or to destabilize. The difference is the intent, not the words, and one rumor can be both depending on who is carrying it.
The machinery is cheap: fake accounts, recycled footage with a fresh caption, out of context quotes, and outlets that launder a claim until it looks reported. The defenses are boring and effective: find who benefits, locate the original, wait for a second source, and treat the claim that confirms everything you already believe with more suspicion rather than less.

Deep state
Two different things wearing one name. In political science it is a durable network inside the state (officers, intelligence services, senior civil servants) that steers policy from behind elected government, a real and documented pattern in countries from Pakistan to Turkey. In American argument it is usually an accusation: unnamed bureaucrats sabotaging a president.
Both uses point at the same real question, which is how much of government is decided by people nobody elected. Answering it needs evidence of specific coordination, not the phrase. On its own it can name genuine institutional resistance, or it can be used to discredit any official who refuses an order, and only the evidence tells you which one you are looking at.

Apartheid
Literally apartness: a legal system that sorts people by race and then rules through that sorting. South Africa built one from 1948 to 1991: the population classified by race, land and residence restricted by law, marriage criminalized across the color line, Black South Africans forced to carry passes, opposition crushed. It ended through internal resistance and international pressure, not through reform handed down from above.
The legal definition matters, because the word is defined in international law as an institutionalized system of oppression and domination by one racial group over another, set up to keep that regime in place. It is not a South Africa only word. In 2022 a United Nations Special Rapporteur concluded that Israel's rule over Palestinians meets that definition. B'Tselem, Human Rights Watch and Amnesty International had each reached the same conclusion earlier from their own investigations.

Genocide
A legal term with a definition written in 1948: acts committed with intent to destroy, in whole or in part, a national, ethnical, racial or religious group as such. The convention lists five acts: killing members of the group, causing serious bodily or mental harm, deliberately inflicting conditions of life meant to bring destruction, preventing births, and forcibly transferring children of the group to another one.
Two parts decide any case: one of those acts, plus the specific intent to destroy the group as such. That intent is why prosecutions take years and why the word is fought over in live conflicts, including matters now before international courts. States rarely announce it, so courts read intent from orders, scale, pattern and the statements of those carrying it out.

Zionism
The national movement of the Jewish people, born in late nineteenth century Europe, when pogroms kept making the case that emancipation had failed and that a homeland of their own was the answer. Political Zionism organized for it, labor Zionism built kibbutzim and unions, revisionist Zionism put military strength first. The state of Israel was founded in 1948. The same year is the Nakba, in which roughly 700,000 Palestinians were displaced or fled.
It is not one thing. Israelis and diaspora Jews hold Zionist and anti-Zionist positions alike, and the label gets used as a self description and as an insult, often carelessly. As a definition it is support for Jewish self-determination in that land. Whether the project has been just in practice is the real argument, and it gets settled on the record: 1948, the 1967 occupation, the settlements, and how people live under military rule.

Free speech and the First Amendment
In the United States the First Amendment says Congress shall make no law abridging freedom of speech, and courts read it to cover speech, press, religion, assembly and petition. Its most important limit for everyday arguments: it restricts the government, not private platforms, employers or neighbors. A social media company removing a post is not a constitutional violation, while a city doing it might be.
It is not absolute either. The classic unprotected categories are true threats, incitement to imminent lawless action, fraud, defamation and obscenity, and time, place and manner rules can apply to anyone. Political speech gets the strongest protection, which is exactly the speech people in power most want restricted.

Gerrymandering
Drawing electoral districts so one party's votes turn into more seats: pack the other side's voters into a few overwhelming districts, and crack the rest across many where they fall just short. The name comes from Elbridge Gerry, a Massachusetts governor whose 1812 district was said to look like a salamander.
Modern mapmaking works from block level voting data, which is why a party can lose the statewide vote and still keep the legislature. Racial gerrymandering is a separate legal question in US law, since race cannot be the predominant factor in drawing lines, though proving and policing that has proven hard.
