The Société Amicale des Originaires de l'Afrique Equatoriale Française was a social and political anti-colonial movement in French Equatorial Africa (A.E.F.).
[3] The association issued two protest letters to the French government in 1928, condemning the economic stagnation in A.E.F.
Matsou's political agitation began in a similar way as Ferhat Abbas' in Algeria, by a public call for civil rights.
The reception was remarkable amongst the Bakongo in the Brazzaville area, and in a few weeks around 100 000 French francs were collected.
They refused to pay taxes and dues to French-initiated saving schemes, and opposed a population and animal census.
The matswanistes withdrew from public life, and transformed themselves into a close-knit secluded religious community.
