Rainbow Group (1984–1989)

The Rainbow Group, officially the Rainbow Group: Federation of the Green Alternative European Links, Agalev-Ecolo, the Danish People's Movement against Membership of the European Community, and the European Free Alliance, in the European Parliament was a green and regionalist political group with seats in the European Parliament between 1984 and 1989.

The Rainbow Group^[5] was formed in 1984^[2] as a coalition of Greens, Regionalists and other parties of the left unaffiliated with any of the international organizations.

The German Greens and the Dutch Green Progressive Alliance were used a principle of rotation used by the Germany and Dutch parties, requiring its MEPs to sit for half their five-year term.

In 1989^[2][5] the Rainbow Group split. The green parties formed the Green Group, whilst the regionalist parties stayed a continuing Rainbow group, with the shorter official name of the Rainbow Group in the European Parliament.
