The Labour Party's origins lie in the late 19th century, when it became apparent that there was a need for a new political party to represent the interests and needs of the urban proletariat, a demographic which had increased in number and had recently been given franchise. Some members of the trades union movement became interested in moving into the political field, and after further extensions of the voting franchise in 1867 and 1885, the Liberal Party endorsed some trade-union sponsored candidates. The first LibLab candidate to stand was George Odger in the Southwark by-election of 1870. In addition, several small socialist groups had formed around this time, with the intention of linking the movement to political policies. Among these were the Independent Labour Party, the intellectual and largely middle-class Fabian Society, the Marxist Social Democratic Federation and the Scottish Labour Party.
