Final answer:
After the king was overthrown in the Eastern Zhou, the Warring States period began, which was marked by inter-state warfare and power struggles, ultimately leading to the rise of the Qin state.
Step-by-step explanation:
What happened after the king was overthrown in the Eastern Zhou?
When the king in the Eastern Zhou dynasty was overthrown, it signaled the beginning of the Warring States period, which lasted from 475 to 221 BCE. During this time, the Zhou dynasty's decentralized feudal system, which had granted regional leaders land and power, ultimately led to their rise in autonomy and eventual warfare among themselves. Seven major states emerged and engaged in continuous battles to expand their territories and seek dominance over China. The Warring States period is characterized by immense armies, strategic alliances, and intense power struggles, eventually leading to the rise of the Qin state as the predominant power.The correct answer to the question is A. The Warring States period began after the overthrow of the king in the Eastern Zhou dynasty. Option B, C, and D do not describe the events that followed the Eastern Zhou. The Shang and Xia dynasties were earlier than the Zhou, and the Zhou Dynasty did not continue without a king.
