ABSTRACT
This chapter discusses the developments of European Society for Research in Mathematics Education (ERME) and Congress of European Research in Mathematics Education (CERME). A Thematic Working Group (TWG) at CERME is important not only as a means of consolidating areas of research, but also as a means of organising the biannual conferences. CERME has attracted participants from outside the European continent, and the internationalisation of these conferences might well be a natural path. The Brazilian Mathematics Education Society has bylaws for creating and closing down thematic groups. There are no indications of ERME groups disbanding, but one can see that several groups within ERME are not present in the Brazilian mathematics society (SBEM). An opposite and additional characteristic of ERME is to have leaders in publications and in the organisation itself that are not from Europe. By comparing and contrasting the two organisations of ERME and SBEM, the author want to show that some themes seem more European.
