Fascistic principles refer to a set of political ideologies and practices characterized by authoritarianism, nationalism, and the suppression of dissent. These principles often involve the centralization of power in a single leader or party, emphasizing the state's interests over individual rights, and promoting a strong sense of national identity. In the interwar period, these ideas gained traction across Europe as societies faced economic hardships and political instability, leading to the rise of fascist regimes that sought to restore order and national pride.
