This essay describes the process for consolidating the Republic in Brazil, showing that the case illustrates the transformative change of political institutions through the action of interest groups. We intend to contribute to bridge two important theoretical gaps. On the one hand, the lack of theorizing about the Brazilian public administration with a historical and non-instrumental approach. On the other hand, the current debate in New Institutionalism about the institutional change processes. Thus, the paper has as its main results the identification and classification of strategies of the republican elites that provided the Brazilian public administration with routines, at the same time that they consolidated the new political regime.
