Belgium is a federal state with a multi-party political system, with numerous parties who factually have no chance of gaining power alone, and therefore must work with each other to form coalition governments.
In the late 19th century, the Labour Party arose to represent the emerging industrial working class.

The most successful Maoist movement to emerge in Belgium was All Power To The Workers (AMADA-TPO) at the end of the 1960s during a time of students protests at the University of Leuven.
A specific phenomenon in Belgium was the emergence of one-issue parties whose only reason for existence was the defence of the cultural, political, and economic interests of one of the linguistic groups or regions of Belgian society.
After a disappointing result in the regional elections of 2009, the Social Liberal Party decided to merge with the Flemish ecologists of Groen!.

The Flemish (Agalev) and Francophone (Ecolo) ecologist parties made their parliamentary breakthrough in 1981.
The foremost Flemish party in Belgium is the Vlaams Belang, which was founded in 2004, after its predecessor was condemned by a High Court for "permanent incitation to discrimination and racism."
