Freedom and People's Rights Movement
The Charter Oath was promulgated on 6 April 1868, which outlined the fundamental policies of the government and demanded the establishment of deliberative assemblies, but it did not determine the details. The idea of a written constitution had been a subject of heated debate within and without the government since the beginnings of the Meiji government. The conservative Meiji oligarchy viewed anything resembling democracy or republicanism with suspicion and trepidation, and favored a gradualist approach. The Freedom and People's Rights Movement demanded the immediate establishment of an elected national assembly, and the promulgation of a constitution.
