As the Bronze Age collapse began across the eastern Mediterranean around 1200 B.C., a mysterious force appeared at sea. Kingdoms were ravaged by a coalition of nautical thieves now known as the Sea Peoples. But who were these warriors and how much did they contribute to the end of the Bronze Age?

Who were the Sea Peoples?

Historians believe the Sea Peoples were not one unified civilization but a coalition of tribes from across the Mediterranean, including the Shekelesh of Sicily, the Shardana of Sardinia, the Lukka and Denyen of Anatolia and the Peleset and Tjeker of the southern Levant.

Scholars hypothesize that the Sea Peoples first emerged around 1250 B.C. after long droughts in the western Mediterranean destroyed crops, caused famine, halted trade and severely weakened major kingdoms. This prompted mass migration to fertile river regions like Egypt, Cyprus, Crete and the Levant (modern-day Syria, Lebanon, Israel and Palestine). But these farmlands and cities were unable to sustain the influx of displaced peoples. As existing bands of raiders and pirates preyed on vulnerable coastal settlements, ordinary citizens might have joined them in order to survive.

Rather than forming a singular army, Sea Peoples were described as migrants who attacked Anatolia, Cyprus, Syria and parts of Egypt for grain and other food. The Syrian trading city of Ugarit was completely destroyed by the Sea Peoples around 1200 B.C. These coastal invasions are estimated to have lasted for a century, between 1276 and 1178 B.C.

How were the Sea Peoples defeated?

The Egyptian pharaoh Ramesses II took action against the Sea Peoples in the early 1270s B.C., when he successfully stationed troops along the Nile Delta to fight them off.

Around 1208 B.C, more action was required. Pharaoh Merenptah and his army contested the Sea Peoples in the Western Delta at the Battle of Perire. After a six-hour battle, the Egyptians prevailed thanks largely to their skilled archers and chariotry. The victory was recorded in the Great Karnak Inscription in the Karnak Temple Complex, Luxor, Egypt.

The Sea Peoples suffered their final major defeat around 1177 B.C. by Pharaoh Ramesses III. After devastating kingdoms such as the Hittite Empire, the Sea Peoples had advanced on Egypt from the Levant where they were repelled by Egyptian troops. The Sea Peoples later mounted another invasion through the Nile Delta, where Ramesses III’s fleet and archers decisively defeated them from the shoreline.

After this, some of the remaining Sea Peoples were absorbed into the Egyptian military, while others settled in Canaan and other parts of the Levant.

Did the Sea Peoples cause the Bronze Age collapse?

The Sea Peoples are thought to have played a significant role in the Bronze Age Collapse, though they were likely one of several contributing factors. Environmental stress, famine and political upheaval had already left many civilizations vulnerable.

By disrupting trade routes across the Mediterranean and destroying major coastal cities, the Sea Peoples contributed to shortages of tin and copper, the two metals needed to produce bronze. Metallurgists eventually turned to iron, which was cheaper and stronger. Over time, this transition helped usher in the Iron Age.
