 To his surprise and chagrin, Caesar had named his grandnephew Gaius Octavius his sole heir (hence the name Octavian), bequeathing him the immensely potent Caesar name and making him one of the wealthiest citizens in the Republic.The crowd at the funeral boiled over, throwing dry branches, furniture, and even clothing on to Caesar's funeral pyre, causing the flames to spin out of control, seriously damaging the Forum.The mob then attacked the houses of Brutus and Cassius, where they were repelled only with considerable difficulty, ultimately providing the spark for the civil war, fulfilling at least in part Antony's threat against the aristocrats.
