A detailed timeline of the BattleTech fictional setting stretching from the late 20th century to the mid-32nd describes humanity's technological, social and political development and spread through space both in broad historical terms and through accounts of the lives of individuals who experienced and shaped that history, with an emphasis on (initially) the year 3025 and creating an ongoing storyline from there.
