Answer:
The Sea Peoples terrorized Egypt and the Mediterranean during the Bronze Age, but their identity and origins remain mysterious to this day.
Explanation:
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.
The social classes of the Qin and Han dynasties were influenced by the tenets of Confucianism. they were patriarchal (men were the most powerful and held the highest social standing) and were largely based on familial piety, among other things. as for the economies, both dynasties employed centralized rule over their economies, and constructed government-owned monopolies over vital goods. both dynasties had centralized political structures ad well, although the Han dynasty attempted to create something that combined the overcentraliztion of the qin dynasty with the decentralization of the Zhou dynasty. this attempt, unfortunately, failed, causing them to use a more centralized political system.
