The leaders present included Okubo Toshimichi, Kido Takayoshi, Itagaki Taisuke, Ito Hirobumi, and Inoue Kaoru. In 1873, Itagaki had withdrawn from the government over the "Seikanron" issue, and was now loudly agitating for representative democracy as the leader of the Freedom and People's Rights Movement. Likewise, in 1874, Kido had withdrawn from the government due to his opposition to the Taiwan Expedition of 1874.
