The siege of Syracuse by the Roman Republic took place in 213–212 BC. The Romans successfully stormed the Hellenistic city of Syracuse after a protracted siege, giving them control of the entire island of Sicily. During the siege, the city was protected by weapons developed by Archimedes. Archimedes, the prominent inventor and polymath, was slain at the conclusion of the siege by a Roman soldier, in contravention of the Roman proconsul Marcellus' instructions to spare his life.
