(en) zabalaza.net: The International Socialist League: laying the foundations Compiled by Warren McGregor (TAAC, ZACF)

What was the ISL and what were its aims? ---- The International Socialist League (ISL) was 
a revolutionary syndicalist political organisation founded in Johannesburg in 1915. Many 
founders were militants who had broken from the South African Labour Party (SALP) over its 
support for the British Imperial war effort in World War I. They were opposed to 
capitalist war and imperialism. ---- The ISL aimed to organise ?One Big Union? of the 
entire South African working class to fight for the overthrow of capitalism and the taking 
over of society by the working class, for the working class. ---- What did the ISL say 
about race? ---- Key to this project in the South African context was the breaking of the 
racial divisions within the working class. This required raising the specific demands of 
black workers for equality with white workers, in order to practically unite all workers 
and to enable them to work together toward ?their common emancipation from wage slavery.?

The ISL consistently condemned racism, and insisted that ?an internationalism which does 
not concede the fullest rights which the native working-class is capable of claiming will 
be a sham.?

What did the ISL actually do?
It disseminated this message through innumerable leaflets and public meetings. It even 
stood of candidates in state elections for propaganda, running on a platform of equal 
rights for white and black, and the abolition of capitalism and the state through the One 
Big Union. The ISL also had a weekly newspaper called The International. It was active in 
the main cities ? except Cape Town.

ISL unions and organising
The ISL was also able to unionise workers of colour into syndicalist unions on the 
Industrial Workers of the World (IWW) model. The first was the Indian Workers? Industrial 
Union (IWIU), launched in Durban in March 1917. In Johannesburg in July 1917 a study group 
for black African workers was set up. At the end of September the same year this became 
the Industrial Workers of Africa (IWA), the first black trade union in South Africa?s 
history. Later it spread to Cape Town.

In 1919 the ISL?s Kimberley branch established the Clothing Workers? Industrial Union 
(CWIU) and the Horse Drivers? Union. The CWIU also spread to other cities. These unions 
had hundreds of members. Many joined the ISL.

Cautious alliances
Last, ISL and IWA members worked with (and in) other opposition groups, including the 
South African Native National Congress (now the African National Congress, or ANC), 
against racist laws. But it never trusted the ANC or set up a formal alliance with it. It 
said the ANC leaders represented the interests of the black elite above all else.
