When and how did the Romans started to worship the Greek Gods?

The Romans began to adopt and worship Greek gods around the 3rd century BCE, particularly during and after the Punic Wars. This process involved assimilating Greek deities and their attributes into Roman religion, often giving them Latin names; for example, Zeus became Jupiter, and Hera became Juno. The influence of Greek culture, particularly through trade, conquest, and the spread of Hellenistic ideas, facilitated this syncretism, leading to a rich tapestry of religious practice that combined elements from both traditions.
