At the urging of Britain and King George, Greece adopted the much more democratic Greek Constitution of 1864. The powers of the King were reduced, the Senate was abolished, and the franchise was extended to all adult males. Approval voting was used in elections, with one urn for each candidate divided into "yes" and "no" portions into which voters dropped lead beads. Nevertheless, Greek politics remained heavily dynastic, as it has always been. Family names such as Zaimis, Rallis and Trikoupis occurred repeatedly as Prime Ministers.
