TheLex Roscia was introduced in 49 BC by the praetorLucius Roscius Fabatus on behalf ofJulius Caesar. It grantedRoman citizenship to the populations in Transpadana, the area ofCisalpine Gaul north of the RiverPo.^[1] In 89 BC, these peoples had already been grantedLatin Rights with theLex Pompeia de Transpadanis.^[2]

With this law Julius Caesar sought to secure the support of the population of Transpadana in the run up toCivil War againstPompey. One of Caesar's most loyal legions was theLegio XEquestris, which was largely recruited from among the population of Cisalpine Gaul. The area had been undergoing decades ofRomanization since the subjugation of theInsubrians in 222 BC. A result of theLex Roscia the Roman and Latincolonies (such asMediolanum andTicinum) became Romanmunicipia. This gave a significant impetus to the urbanization of this region.
