Tiberius was elected praetor for 180 BC, a post that required men to be at least 40 years of age according to the
cursus honorum, which brings estimates of his birth to around 220 BC. Following his praetorship, he took up the governorship of
Hispania Citerior in 179 BC after successfully objecting to his predecessor's attempt to have the army in Hispania recalled for a triumph on the grounds that the task was not yet done. He served there
pro consule from 179 to 178 BC. Rome had been fighting a prolonged and continuous conflict in Iberia since the mid-190s BC. While governor and in conjunction with the other Spanish governor,
Lucius Postumius Albinus, he campaigned successfully against the Celtiberians, Lusitanians, and other hostile groups while negotiating treaties to ensure a prolonged peace. In the coming two decades, Roman expansion in Spain also took a lower priority as the senate focused Rome's military resources on Macedonia. The Gracchan agreements seem to have mainly been related to tribute arrangements; the details are largely lost. During his governorship of Hispania Citerior, he also founded the city of Gracchuris in 178 BC, on the river Ebro, becoming the first Roman to name a city after himself. Gracchus claimed to have destroyed three hundred cities during his campaigns in Spain (almost certainly an exaggeration). Upon his return, the senate awarded him a triumph "over Lusitania and Spain" where he and his colleague Albinus presented some 60 thousand pounds of silver. In 177 BC, he was elected consul with
Gaius Claudius Pulcher. He was posted to Sardinia, where he suppressed a revolt assisted by propraetor Titus Aebutius Parrus. He waged two "ruthless" campaigns, fighting the Ilienses and the Balari, forcing their submission. At the close of 175 BC, he returned to Rome, claiming he had killed and captured some 80 thousand Sardinians, and triumphed for the second time in 175 BC. He was elected
censor starting in 169 BC with his former consular colleague Gaius Claudius Pulcher. The censors helped raise men for the war against Macedon, and was so strict that it provoked a prosecution of his colleague Claudius. Claudius was narrowly acquitted with Gracchus' help. Supposedly, during his censorship, citizens extinguished their lights when Gracchus passed at night from fear of being thought overly indulgent. While censor in 168 BC, he restricted the votes of freedmen by registering all of them into just one of the urban tribes over the objection of his colleague Claudius. He also had the
basilica Sempronia constructed in the Roman forum; the request of theirs, however, to see the building programme to completion was vetoed. After his censorship, in 165 BC, Gracchus was dispatched as head of an embassy to various eastern kingdoms on a mission to investigate the attitudes thereof to Rome, reporting that all had favourable views of the Romans. In 163 BC, Tiberius was again elected consul. When performing the
auspices when conducting the consular elections for 162 BC, he committed a procedural error: after observing a negative omen, he crossed the
pomerium to consult the senate and therefore relinquished the
auspicia militiae needed to hold the election. He discovered this procedural error after his successors had taken office and he had arrived in Sardinia for his promagistracy, whereon he reported it to the senate. The consuls were forced to resign, one of which was his brother-in-law
Publius Cornelius Scipio Nasica Corculum, husband of his wife's elder sister. == Later life ==
