A major proponent of representative government was Itagaki Taisuke (1837–1919), a powerful Tosa leader who had resigned from the Council of State over the Korean affair in 1873. Itagaki sought peaceful, rather than rebellious, means to gain a voice in government. He started a school and a movement aimed at establishing a constitutional monarchy and a legislative assembly. Such movements were called The Freedom and People's Rights Movement. Itagaki and others wrote the Tosa Memorial () in 1874, criticizing the unbridled power of the oligarchy and calling for the immediate establishment of representative government.
