Question

millennium The first millennium B.C. saw the rise of important civilizations in Greece, Rome, India, Central America, and China. məˈlɛniəm

Accepted Answer

(1) A period of time lasting 1,000 years, or the celebration of a 1,000-year anniversary. (2) A period of great happiness and perfection on earth. Since in Latin mille means “thousand” (see MILL), a millennium lasts 1,000 years. Thus, we're living today at the beginning of the third millennium since the birth of Christ. But some religious sects, relying on a prophecy in the biblical Book of Revelation, speak of a coming millennium when Jesus will return to reign on earth for 1,000 years, evil will be banished, and all will live in peace and happiness. Members of these sects who keep themselves in a constant state of preparedness are called millenarians or millennialists
