Summary. The crisis in the Brazilian Senate, which started with accusations of corruption against the president, spread to the Legislative Power and even the Executive. The article maintains that this crisis is a reflection of a general crisis in political parties and modern parliaments, resulting from the pressure of governmental decisiveness and social spontaneity, which limits the Legislature’s ability to act. At its heart, this is a consequence of a situation of wider institutional unease, a crisis of political subjectivity, in which political systems become incapable
of interacting with a culture and society produced by the new terms in globalized life.
