The Flavian Dynasty was a Roman imperial family that ruled from 69 to 96 AD. It began with Vespasian, who came to power after the chaotic Year of the Four Emperors. The dynasty is known for significant military successes, including the conquest of Britain, and for initiating major construction projects, such as the Colosseum in Rome. The Flavian emperors included Vespasian, his sons Titus and Domitian. Titus is remembered for his handling of the eruption of Mount Vesuvius and the subsequent relief efforts. The dynasty ended with the assassination of Domitian, leading to a transition to the Nerva-Antonine Dynasty.
