Therefore, in 1899 the cooperation between both groups advanced and in December of the same year the members of Mokuyo-kai (Thursday-group) and independents were invited to form a union with 70 members against party politics.
そこで1899年に入ると両会派の連携が進み、同年12月に両会派が木曜会や純無所属の議員にも呼びかけて70名の議員によって政党政治に反対する連合組織を結成した。
