On 24 April 1966, Belgian communist youth marched through the streets of Brussels against imperialism in Congo. In Congo – the former Belgian colony that had become independent in 1960 – chaos reigned. Time and again, foreign powers – Belgium most of all – felt compelled to intervene. In 1964, a Marxist oppositional government had been liquidated with the help of Belgian mercenaries. The Congolese rebels, including the Simba ('Lions') were also the object of intervention from abroad. The Peoples Republic of China gave support and a small mercenary army from Cuba was active in Congo. However, the anti-imperialism of the Belgian communists did not include these countries.
