In 1927, a non-binding plebiscite took place in Cerro Chato to decide to which department it would belong: Durazno, Florida or Treinta y Tres. For this referendum, every citizen of the town was called to vote, including women. That was the first time in Latin America that women exercised the right to vote. The Department of Durazno won the plebiscite, but this result was not accepted by the authorities. Therefore, Cerro Chato still is split between the three departments.
