Governed by the 1969 Constitution , the ALMS came from the first Constituent State Assembly of Mato Grosso do Sul, created on January 1, 1979 by the then president of the republic Ernesto Geisel, as part of complementary law 31, which dismembered the southern portion from the state of Mato Grosso to create a new state. On June 13, 1979, the state constitution was enacted, which gave the house its current name.

Years later, following the determination of the Federal Constitution of 1988, the Legislative Assembly, invested with Constituent Power, elaborated the second Magna Carta, promulgated on October 5, 1989. From the foundation until today there were 10 legislatures, with 18 parliamentarians at the beginning and since the second legislature there are 24.
