What was the Period of Warring States?
As the Zhou Dynasty weakened, nomads from the north and west sacked the Zhou capital and murdered the Zhou monarch. A few members of the royal family escaped and set up a new capital at Luoyang. But, these kings at Luoyang were almost powerless, and they could not control the noble families. The lords were constantly fighting with neighboring lords. As their power grew, these lords claimed to be kings in their own territory.
