World government

Notion of a single common political authority for all of humanity

World government is a theoretical single political authority with jurisdiction over all of Earth and humanity. A world government with executive, legislative, and judicial functions and an administrative apparatus has never existed. The inception of the United Nations (UN) in the mid-20th century remains the closest approximation to a world government, as it is by far the largest and most powerful international institution.
