Overview
Aulus Sempronius Atratinus was a consular tribune of the Roman Republic in 425, 420, 416 BC and possibly consul in 428 BC.
Sempronius belonged to the patrician branch of the Sempronia gens. He was the son of Lucius Sempronius Atratinus, consul in 444 BC and one of the first censors of the Republic. Gaius Sempronius Atratinus, consul in 423 BC and a contemporary relative was probably a cousin (son of Aulus Sempronius Atratinus) or a younger brother.
Career
In 428 or 427 BC Sempronius held the consulship together with Lucius Quinctius Cincinnatus. This consulship is dubious as it is only mentioned by Diodorus Siculus and is placed in-between the consuls of 428, Aulus Cornelius Cossus and Titus Quinctius Poenus Cincinnatus, and the consuls of 427 BC, Gaius Servilius Structus Ahala and Lucius Papirius Mugillanus. It is possible that they were suffect consuls replacing the college of 428 BC or that all four consuls mentioned in 428 were consular tribunes. All events described by other ancient authors are ascribed to the ordinary consuls of 428 BC.
Sempronius was elected as consular tribune in 425 BC together with (possibly his former consular colleague) Lucius Quinctius Cincinnatus, Lucius Furius Medullinus and Lucius Horatius Barbatus. They oversaw the signing of a twenty year truce with Veii and a three year truce with the Aequi.
