The Licinian Rogations began in 375 when two tribunes of the Plebs, Licinius Stolo and L. Sextius (L. Sextius Sextinus Lateranus), made rogationes (proposals that could become law) about debt, the ager publicus and that one of the consuls might be a plebeian. Eight years later, the same 2 tribunes were still in power. Stolo and Sextius were more powerful than ever having stopped legislation during their terms in office by means of the primary tribunician power -- the veto; and so, in 367, they got their way, and the plebeian Sextius was elected consul, along with the patrician L. Aemilius Mamercinus. The law about the public land included a provision that no one would graze more than 100 large and 500 smaller animals on the public pastures. Licinius himself was affected by this law. The three rogationes were included in a Lex Satura meaning that it was a law dealing with disparate matters.
