A compromise proposal presented by Hannes in spring 1913 was heavily criticized in the Icelandic press, and the Union Party split into three factions, a group that continued to support Hannes, a restored Home Rule Party under the leadership of Lárus H. Bjarnason and a Farmers' Party.[2] Hannes succeeded in getting most of the party's MPs members reunited, apart from four MPs that continued as the Farmers' Party, and a constitutional proposal was finally approved in the fall of 1913. Upon reunification the party was formally registered as the Home Rule Party,[2] but was still commonly known as the Union Party. The supporters of Hannes lost the 1914 election and he subsequently resigned. The constitutional proposal was approved for a second time by the Althing in 1914 and formed the basis for the union treaty of 1918.
