Democratic consolidation is the process by which a new democracy matures, in a way that means it is unlikely to revert to authoritarianism without an external shock. The notion is contested because it is not clear that there is anything substantive that happens to new democracies that secures their continuation beyond those factors that simply make it 'more likely' that they continue as democracies. Unconsolidated democracies suffer from formalized but intermittent elections and clientelism.
