Lucius Aemilius Paullus Macedonicus (c. 229 BC – 160 BC) was a two-time consul of the Roman Republic and a noted general who conquered Macedon, putting an end to the Antigonid dynasty in the Third Macedonian War.
His father was Lucius Aemilius Paullus, the consul defeated and killed in the battle of Cannae. Lucius Aemilius was, in his time, the head of his branch of the Aemilii , an old and aristocratic patrician family. Their influence was immense, particularly due to their fortune and alliance with the Cornelii Scipiones. He was father to Scipio Aemilianus Africanus.
After the fulfilment of his military service, and being elected military tribune, Paullus was elected curule aedile in 193 BC. The next step of his cursus honorum was the election as praetor in 191 BC. At the term of this office he went to the Hispania provinces, where he campaigned against the Lusitanians between 191 and 189 BC. However, he failed to be elected consul for several years. Paullus was elected consul for the first time in 182 BC, with Gnaeus Baebius Tamphilus as junior partner. His next military command, with proconsular imperium, was in the next year, against the Ingauni of Liguria.
The Third Macedonian War broke out in 171 BC, when king Perseus of Macedon defeated a Roman army led by the consul Publius Licinius Crassus in the battle of Callinicus. After two years of results indecisive for either side, Paullus was elected consul again in 168 BC (with Gaius Licinius Crassus as colleague). As consul, he was appointed by the senate to deal with the Macedonian war. Shortly afterwards, on June 22, he won the decisive battle of Pydna. Perseus of Macedonia was made prisoner and the Third Macedonian War ended.
