Latin rights or Latin citizenship (Latin: ius Latii or ius latinum) were a set of legal rights that were originally granted to the Latins and therefore in their colonies (Latium adiectum). Latinitas was commonly used by Roman jurists to denote this status. With the Roman expansion in Italy, many settlements and coloniae outside of Latium had Latin rights.
All the Latini of Italy obtained Roman citizenship as a result of three laws which were introduced during the Social War between the Romans and their allies among the Italic peoples (socii) which rebelled against Rome. The Lex Iulia de Civitate Latinis (et sociis) Danda of 90 BC conferred Roman citizenship on all citizens of the Latin towns and the Italic towns who had not rebelled. The Lex Plautia Papiria de Civitate Sociis Danda of 89 BC granted Roman citizenship to all federated towns in Italy south of the River Po (in northern Italy). The Lex Pompeia de Transpadanis of 89 BC granted the ius Latii to the communities of Transpadania, a region north of the Po, which had sided with Rome during the Social War. It also granted Roman citizenship to those who became officials in their respective municipia (cities).
