chiliasm
1. The doctrine stating that Jesus will reign on earth for 1,000 years.

The term millennium comes from Latin, "1,000 years", the period of 1,000 years in which, according to some schools of Christian eschatology (theology or religious beliefs), Christ will reign again gloriously on earth.

Belief in the millennium, based on the book of Revelations 20 in the Bible, has recurred in Christianity since the earliest times. Today it is held and taught by the Adventists and some other conservative evangelical bodies. Belief in the millennium is called chiliasm by historians of the ancient church.
