The Revive China Society, founded in November 1894 by Sun Yat-sen, was among the first to suggest that a future Chinese government should be established on federal lines—a feeling expressed in the organisation's oath, "Expel the northern barbarians, revive "Zhōnghuá", and establish a unified ("hézhòng") government". The term "hézhòng", literally meaning "many unified as one", refers to a federal structure such as the United States of America.
