Lucius Tarquinius Priscus, also known as Tarquin the Elder, was the fifth king of Rome and reigned from 616 to 579 BC. He was one of Rome’s most influential and strategic kings, and his reign played a significant role in elevating Rome from a small city-state to a powerful kingdom. Born to a noble Etruscan family, Tarquin immigrated to Rome with his wife, Tanaquil, where his ambitious nature and charismatic leadership quickly gained him the admiration and support of its people, leading to his appointment as king following the death of the previous ruler, Ancus Marcius. During his forty-year reign, Lucius Tarquinius Priscus was instrumental in implementing several significant civic and military reforms. He doubled the size of Rome’s original infantry legions, improved the city’s infrastructure, and launched numerous construction projects such as the creation of Rome’s great sewer system, the Cloaca Maxima, and the Circus Maximus, an ancient Roman chariot-racing stadium. Under Tarquin’s rule, Rome grew exponentially, both territorially and in terms of its political and military power. Despite his successful reign, his life came to a brutal end when he was assassinated by the sons of Ancus Marcius, who saw their birthright stolen. However, his legacy lived on as Rome continued to thrive long after his death.
