Artistic movements are temporary coalitions. A group of artists, often in the same place at the same time, share a set of aesthetic commitments — a style, a technique, a subject matter, a philosophical orientation. They exhibit together, publish manifestos, influence each other. Then the movement dissolves.
The dissolution of an artistic movement has a characteristic arc. First comes the heroic period: the core group produces its most radical work. Then comes the period of diffusion: the style is adopted by a wider circle, diluted in the process. Then comes the period of reaction: a new generation rejects the movement's premises and defines itself in opposition. The movement dissolves not because it failed but because it succeeded too well — its innovations become the new normal, and the normal is never radical.
Some dissolutions are dramatic. The surrealists expelled members with a regularity that rivalled the Communist Party. Others are gradual. The impressionists simply stopped exhibiting together after 1886, having achieved their goals and exhausted their solidarity. In both cases, the dissolution is not a failure but a completion. The movement has done what it was formed to do. What remains is influence, which is harder to dissolve than membership.
The dissolution of an artistic movement is a reminder that all collective enterprises are temporary. They form around shared commitments; they dissolve when those commitments are fulfilled, abandoned, or superseded. The work remains. The movement does not.
