Vespasian, founder of the Flavian dynasty, was a renowned military commander and took part in both the Roman invasion of Britain in 43 CE and the Roman subjugation of the First Jewish Revolt in 69 CE. On the death of Nero, he was one of the four rival claimants for the throne and emerged as the ultimate victor. He began construction of the Colosseum in Rome. In modern Romance languages, urinals are still named after him (for example, vespasiano in Italian, and vespasienne in French), probably in reference to a tax he placed on urine collection.
