The gens Laelia was a plebeian family at Rome. The first of the gens to obtain the consulship was Gaius Laelius in 190 BC.^[1]

Branches and cognomina

The only family name of the Laelii was Balbus, a common cognomen, referring to one who stammers. A few of the Laelii used personal surnames, such as Sapiens ("wise"), by which the Laelius who was a friend of the younger Scipio Africanus was sometimes known.^[1][2][3]

Early Laelii

• Gaius Laelius, grandfather of Gaius Laelius, consul in 190 BC.
• Gaius Laelius C. f., the father of Gaius Laelius, consul in 190 BC.
• Gaius Laelius C. f. C. n., consul in 190 BC, was a friend of the elder Scipio Africanus, to whom he acted as legate throughout the Second Punic War. After his consulship, he helped colonize the territory of the Boii. He was appointed to several other commissions and embassies through 170.^{[4][5][6][7][8][9][10]}
• Gaius Laelius C. f. C. n. Sapiens, consul in BC 140, and a close friend of the younger Scipio Africanus. He initially favoured agrarian reform, but after meeting resistance abandoned the effort, and opposed the efforts of the Gracchi, leading his aristocratic contemporaries to call him Sapiens, "the wise". He was erudite and refined, but a less persuasive speaker than some of his contemporaries.^{[11][12][13][14][15][16][17][18][19]}
• Laelia C. f. C. n. Major, married Quintus Mucius Scaevola, the augur. Laelia was renowned for her graceful and eloquent speech, dignified and sincere, upon which Cicero remarked, and which she passed down to her daughters, as well as her son-in-law, the orator Lucius Licinius Crassus.^[20]
• Laelia C. f. C. n. Minor, married Gaius Fannius Strabo.^[21]

Laelii Balbi

• Decimus Laelius D. f., impeached Lucius Valerius Flaccus for repetundae in his administration of Asia, BC 59. During the Civil War, Laelius was a loyal commander and emissary in the Pompeian forces.^[26][27][28]
• Decimus Laelius D. f. D. n. Balbus, quaestor pro praetore in Africa in 42 BC, took his own life following the defeat of Quintus Cornificius by Titus Sextius, who had been nominated proconsul by the triumvirs.^[29][30]

Balbus, a delator during the reign of Tiberius, accused Acutia, formerly the wife of Publius Vitellius, of majestas; she was condemned, but the tribune of the plebs Junius Otho prevented Balbus from receiving a reward. Shortly thereafter, Balbus was himself condemned and banished, as one of the lovers of Albucilla. He seems to have been rehabilitated, as he was consul suffectus in 46.^[33][34][35]
