More than 2,000 years before the Vikings first set sail from modern-day Scandinavia to plague the people of Europe, the great empires of the ancient world faced a terrifying seafaring enemy of their own — one that remains almost a complete mystery to this day.
“They came from the sea in their warships and none could stand against them,” ominously proclaimed one inscription written in the 13th century B.C. and later found at the Egyptian city of Tanis.
They were the Sea Peoples, the modern name given to the naval warriors who reportedly wreaked havoc upon the Mediterranean time again between the approximate years of 1400 B.C. and 1000 B.C. but whose identity and origins are largely shrouded in mystery.
Slavery started in colonies because the colony was mainly found by plants from the Barbados who brought large amounts of African slaves from the island to establish new plantations and to meet agricultural needs .
The Stone Age is divided in three distinct periods: the Paleolithic Period or Old Stone Age (30,000 BCE–10,000 BCE), the Mesolithic Period or Middle Stone Age (10,000 BCE–8,000 BCE), and the Neolithic Period or New Stone Age (8,000 BCE–3,000 BCE).
