Memory Omega was founded by Spock before the fall of the Terran Republic and the emergence of the Klingon-Cardassian Alliance that took its place. In the beginning, it served mainly as a repository for the knowledge of the fallen republic. However, the long term plan determined by Spock prior to his death, set out a timetable, spanning a century, for the restoration of freedom. The timetable was carefully orchestrated to predict the forthcoming political and social events within the Alliance, allowing Memory Omega to covertly act to bring about a better society.
