Answer 1

An important milestone marked by the formation of the Roman Republic was the introduction of a system of elected leaders. The Roman Republic, established around 509 BC after the overthrow of the last Roman king, instituted a government where officials such as consuls and senators were elected by the citizens of Rome, representing a significant shift from monarchy to a more democratic form of governance. The other options, such as the invention of the printing press (which occurred much later, in the 15th century) and the construction of the Colosseum (which began in AD 70 and was completed in AD 80), are unrelated to the establishment of the Republic.
