The International African Service Bureau (IASB) was a pan-African organisation founded in London in 1937 by West Indians George Padmore, C. L. R. James, Amy Ashwood Garvey, T. Ras Makonnen and Kenyan nationalist Jomo Kenyatta and Sierra Leonean labour activist and agitator I. T. A. Wallace-Johnson.
Similar in design and organization to the West African Youth League,[2] the IASB also sought to inform the public about the grievances faced by those in colonial Africa and created a list of desired reforms and freedoms that would help the colonies.
The bureau also hoped to encourage new African trade unions to affiliate themselves with the British labour movement.
[3] To further its interest, it held weekly meetings at Hyde Park, where members discussed labor strikes in the Caribbean and Ethiopia.
[5] In 1939 the IASB worked alongside the League of Coloured Peoples and the West African Students Union to campaign against the colour bar introduced by Adjutant-General Robert Gordon-Finlayson in the British Army.
