ABSTRACT
One of the distinguishing circumstances of the organizational evolution – of the evolution tout court as well – of the two Belgian Green parties, Ecolo and Agalev (Groen! from 2003 onwards) is that both these parties have, basically, never been extra-parliamentary parties. Their institutionalization started as early as 1981, when both of them won seats in Parliament, the first time in history when Greens were able to form a full-size parliamentary group.
