In this article, I analyze the relational configurations that, in diverse moments, delimit a particular governmental figure. We use the term «figure» in order to demonstrate the process through which the meaning assigned to a particular term is transformed over time as a result of the modifications of the relational frameworks that condition the objective possibilities of acceding to an office. This approach circumscribes our empirical analysis of the trajectories of members of the Legislative Assembly of Buenos Aires between 1822 and 1996.
