Fascism (/ˈfæʃɪzəm/ FASH-iz-əm) is a far-right, authoritarian, and ultranationalist political ideology and movement.[1][2][3] It is characterized by a dictatorial leader, centralized autocracy, militarism, forcible suppression of opposition, belief in a natural social hierarchy, subordination of individual interests for the perceived interest of the nation or race, and strong regimentation of society and the economy.[2][3] Opposed to communism, democracy, liberalism, pluralism, and socialism,[4][5] fascism is at the far right of the traditional left–right spectrum.[6][5][7]
Fascism views forms of violence including political violence, imperialistviolence, and war as means to national rejuvenation.[11][12] Fascists often advocate for the establishment of a totalitarian one-party state,[13][14] and for a dirigiste economy (a market economy in which the state plays a strong directive role through economic interventionist policies), with the principal goal of achieving autarky (national economic self-sufficiency).[15][16]Fascism’s extreme authoritarianism and nationalism can manifest as a belief in Manifest Destiny or a revival of historical greatness (like Mussoliniseeking to restore the Roman Empire). It may also centre around an ingroup-outgroup opposition. In the case of Nazism, this involved racial purity and a master race which blended with a variant of racism and discrimination against a demonized “Other“, such as Jews and other groups. Other marginalized groups such as homosexuals, transgender people, ethnic outgroups, or immigrants have been targeted. Such bigotry has motivated fascist regimes to commit massacres, forced sterilizations, deportations, and genocides.[17][18] During World War II, the genocidal and imperialist ambitions of the fascist Axis powers resulted in the murder of millions of people.

For a more simplified definition
Fascism is a far-right[1] form of government where most of the country‘s power is held by one ruler or a small group, under one party.[2][3]
Fascist states are usually totalitarian one-party states,[4] which prey on masses of angry, atomized and desperate individuals to make them unite behind a strong man who promises them a utopia and revenge on those who may have harmedthem.[5]
The power of such totalitarianism comes from mass mobilization via the mechanism as mentioned,[4][5] while voluntary collaboration at every level of society by those agreeing with the same goal is necessary for maintaining the totalitarian state.[4][5]
