Coming to the fore in the 1960s, an anti-psychiatry movement challenged the fundamental claims and practices of mainstream psychiatry. The ex-patient movement of this time contributed to, and derived much from, antipsychiatry ideology, but has also been described as having its own agenda, described as humanistic socialism. For a time, the movement shared aims and practices with "radical therapists", who tended to be Marxist. However, the consumer/survivor/ex-patients gradually felt that the radical therapists did not necessarily share the same goals and were taking over, and they broke away from them in order to maintain independence.
