Lucius Junius Brutus
With a sudden and bloody palace coup, the pair deposed and murdered the king, and Lucius seized the throne. Lucius' second son was named after his murdered brother; but it was the overweening pride and arrogance of Lucius' sons that brought about the downfall of the Roman monarchy. The younger Arruns fell in battle against the consul Lucius Junius Brutus in 509 BC.
