Duke of Zhou vs Tokugawa Ieyasu

After King Wu's death, the Duke of Zhou served as regent for the young King Cheng. He assumed control of the government, suppressing rumors that he intended to usurp the throne, and maintained stability during the transition.

The Duke of Zhou led a military campaign to crush the Rebellion of the Three Guards, a revolt by Zhou princes and Shang loyalists. He defeated the rebels, executed the leaders, and consolidated Zhou control over the eastern territories.

The Duke of Zhou ordered the construction of the eastern capital at Luoyi (modern Luoyang) to better administer the newly conquered eastern territories. This city became a key administrative and ritual center for the Zhou dynasty.

The Duke of Zhou is credited with codifying the Zhou ritual system, including rules for ancestral worship, court ceremonies, and social hierarchy. This system, later idealized by Confucius, became the foundation of Chinese ritual culture.

The Duke of Zhou is traditionally attributed with composing the 'Shao Gao' (Announcement of the Duke of Shao) and 'Luo Gao' (Announcement Concerning Luo) chapters of the Book of Documents. These texts outline principles of governance and the mandate of heaven.

After seven years of regency, the Duke of Zhou voluntarily relinquished power to King Cheng, who had come of age. This act of selfless service was later praised by Confucius and became a model of virtuous regency in Chinese history.

Tokugawa Ieyasu led the Eastern Army to victory over Ishida Mitsunari's Western Army at Sekigahara. This decisive battle ended the Sengoku period and established Ieyasu as the supreme military ruler of Japan, paving the way for the Tokugawa shogunate.

Emperor Go-Yozei appointed Tokugawa Ieyasu as shogun, officially beginning the Tokugawa shogunate. Ieyasu established his government in Edo (modern Tokyo), centralizing military and political power under his family's control.

Tokugawa Ieyasu besieged Osaka Castle, the stronghold of Toyotomi Hideyori. The castle fell, and Hideyori committed suicide. This campaign eliminated the last major opposition to Tokugawa rule, solidifying the shogunate's control over Japan.

Ieyasu issued the Laws for the Military Houses, a code regulating the conduct of daimyo. It restricted castle construction, required alternate attendance in Edo, and prohibited alliances without shogunal permission. This law helped control the feudal lords.

In his final years, Ieyasu began policies that led to Japan's isolation. He restricted foreign trade to specific ports and expelled Christian missionaries. These measures, expanded by successors, resulted in the sakoku policy that isolated Japan for over 200 years.
