 Collatinus' ascendency was short-lived; although he himself had suffered at the hands of the king, and ushered in the Republic, he soon became the object of revulsion from those who would not abide any of the Tarquins in power at Rome.Collatinus was dumbstruck when Brutus, his colleague and cousin, called upon him to resign, but resisted until his father-in-law, Lucretius, added his voice to the chorus.Fearing what might become of him should he refuse the popular demand, Collatinus laid down the consulship and went into exile at Lanuvium.
