Settlement began in 1946 on lands belonging to the municipality of Iporá. A local rancher, Edmundo Benuto Dias, donated land for a new settlement which was called Aropi, the inversion of the name Iporá. In 1954, it was elevated to the category of district with the new name of Mendelândia, after Antônio Mendes, one of the pioneers of the region. In 1955, the name was changed to Diorama, of unknown origin. In 1958, it became a municipality.
