Malinowski and Radcliffe-Brown's influence stemmed from the fact that they, like Boas, actively trained students and aggressively built up institutions that furthered their programmatic ambitions. This was particularly the case with Radcliffe-Brown, who spread his agenda for "Social Anthropology" by teaching at universities across the British Commonwealth. From the late 1930s until the postwar period appeared a string of monographs and edited volumes that cemented the paradigm of British Social Anthropology (BSA). Famous ethnographies include "The Nuer," by Edward Evan Evans-Pritchard, and "The Dynamics of Clanship Among the Tallensi," by Meyer Fortes; well-known edited volumes include "African Systems of Kinship and Marriage" and "African Political Systems."
