Final answer:
Iron weapons were brought to Greece by the Dorians, who contributed to the transition from the Bronze Age to the Iron Age. The Phoenicians, skilled traders and sailors, also spread across the Mediterranean searching for iron sources, while the Assyrians were notable for mass-producing iron weapons.
Step-by-step explanation:
The people who brought iron weapons to Greece were the Dorians, who are often credited with ushering in the Iron Age in the region. Following the collapse of the Bronze Age, around 1100 BCE, the use of bronze became more difficult due to disruptions in trade that made tin scarce. Craftsmen turned their attention to iron ore, which led to the development of stronger and more effective iron weapons.
It was during the ensuing Iron Age that the Phoenicians and Greeks expanded throughout the Mediterranean, establishing trade networks and building new societies. The Phoenicians were pioneers in this new age, leveraging their extensive maritime capabilities to set up trading posts far and wide, in part to access iron ore. Over time, this shift also played a role in the military strategies of emerging powers like the Assyrians, who mass-produced iron weapons to equip their formidable armies.
