Final answer:
Democracy is a form of government where the majority of citizens hold the right to govern, while a failed state has little or no control over its territory and a decolonization refers to former colonies governing themselves.
Step-by-step explanation:
Democracy is a form of government in which the right to govern is held by the majority of citizens within a country or a state. In a democracy, all citizens have equal access to power and enjoy universally recognized freedoms and liberties. It allows citizens to choose and replace the government through free and fair elections, ensures active participation of citizens in politics and civic life, protects human rights and civil liberties, and upholds the rule of law. A failed state refers to a government that has little or no control over its territory and is unable to provide basic public services to its citizens. It is characterized by political instability, economic collapse, and social disintegration. Decolonization refers to the process of former colonies gaining independence and governing themselves. It involves the transfer of power from colonial rulers to the local population and the establishment of self-governing institutions.
