The liberals dominated government from the 1893 election to 1905 election with the support of the South Australian United Labor Party, with the conservatives mostly in opposition . Labor took government with the support of eight dissident liberals in 1905 when Labor won the most seats for the first time . The rise of Labor saw non-Labor politics start to merge into various party incarnations . </P>
