Hollanditis was a term coined in 1981 by the American historian Walter Laqueur. It was used to describe the wave of pacifist neutralism that swept through the Netherlands in the first half of the 1980s and which influenced similar grass roots movements in other European countries. It was the biggest popular movement in the Netherlands in the post-war era and it came as a response to the confrontational politics of the Reagan administration in the US that were seen as a threat to the peaceful co-existence of the 1970s.
