What does millennialism mean?
Millennialism has two broadly recognizable uses. In its traditional religious sense, it denotes belief in or advocacy of a millennium—a thousand-year age, especially the anticipated reign of Christ or another messianic figure. Such expectations appear in Jewish and Christian eschatology, though the precise interpretation of scriptural passages has varied widely. In contemporary secular usage, millennialism refers to attitudes, values, or lifestyles attributed to people born around the turn of the twenty-first century. This newer usage is frequently evaluative: writers invoke it when criticizing perceived superficiality, financial instability, technological dependence, or changing attitudes toward work and social institutions. Because it often relies on broad generalizations about a large and diverse generation, the term can carry a negative or dismissive connotation and should not be treated as an objective description of every younger adult. In religious scholarship, millennialism and the closely related millenarianism are often used interchangeably. The word is therefore useful for distinguishing a specific eschatological doctrine from the modern practice of invoking a generational stereotype.
nounMillennialism may denote the religious belief in a thousand-year future, especially a messianic reign on earth, or, in modern usage, the attitudes and lifestyle supposedly characteristic of the millennial generation. The secular sense is often critical and is typically used to discuss a perceived generational outlook rather than a formal doctrine.

From the Latin for “a thousand years,” millennialism began as a religious hope and now often serves as a label for a generational stereotype.

Where does millennialism come from?
The word combines Latin millennium, literally “a thousand years,” from mille “thousand” and annus “year,” with the English suffix -ism. Millennium entered English in the late sixteenth century, and terms based on it were used for doctrines concerning a thousand-year kingdom by the seventeenth century. Christian millennialism developed within older Jewish and Christian expectations of a final messianic age; related forms include millenary, millenarian, and millenarianism.

How millennialism is actually used
The religious sense is formal and common in theology, religious studies, and historical writing. The secular sense is comparatively recent, usually evaluative, and often negative: it attributes perceived traits to millennials collectively and can therefore function as a dismissive stereotype. Context is important because “millennial” can also describe a thousand-year period without referring to either sense.
Easily confused with millennialism
The terms often overlap in religious scholarship, but millennialism also has a modern secular use for stereotypes or attitudes attributed to the millennial generation.
