The British government targeted the American civil rights leader Stokely Carmichael and sought to weaken the Black Power movement with covert disinformation campaigns through the work of a secret unit known as the Information Research Department, based in London and part of the Foreign Office, which created and distributed literature from fake sources as part of a broader effort to destabilise cold war enemies.
The IRD created a fake west African organisation called The Black Power – Africa’s Heritage Group
The IRD’s effort did not attack Carmichael as a pro-Soviet or communist stooge, a hitherto frequent line of attack. Instead, the unit sought to portray its target as a traitor to other Black Power activists with a patronising attitude to African peoples.

In 1969, the IRD also created a new fake group: The Organisation of African Students for African Power. This was supposedly based in East Germany and adopted contemporary radical New Left ideas, “proclaiming a plague on both” the capitalist west and the Soviet bloc.
