Disruption

Some democratic governments have experienced sudden state collapse and regime change to an undemocratic form of government. Domestic military coups or rebellions are the most common means by which democratic governments have been overthrown. (See List of coups and coup attempts by country and List of civil wars.) Examples include the Spanish Civil War, the Coup of 18 Brumaire that ended the First French Republic, and the 28 May 1926 coup d'état which ended the First Portuguese Republic. Some military coups are supported by foreign governments, such as the 1954 Guatemalan coup d'état and the 1953 Iranian coup d'état. Other types of a sudden end to democracy include:

Democratic backsliding can end democracy in a gradual manner, by increasing emphasis on national security and eroding free and fair elections, freedom of expression, independence of the judiciary, rule of law. A famous example is the Enabling Act of 1933, which lawfully ended democracy in Weimar Germany and marked the transition to Nazi Germany.

Temporary or long-term political violence and government interference can prevent free and fair elections, which erode the democratic nature of governments. This has happened on a local level even in well-established democracies like the United States; for example, the Wilmington insurrection of 1898 and African-American disfranchisement after the Reconstruction era.
