Ashoka the Great vs Tokugawa Ieyasu

Ashoka launched a brutal conquest of the Kalinga region (modern Odisha). The war caused massive casualties, with over 100,000 killed and 150,000 deported. The suffering witnessed during this campaign led Ashoka to renounce military conquest and embrace Buddhism.

After the Kalinga War, Ashoka converted to Buddhism under the guidance of Buddhist monks. He adopted the principle of Dhamma (righteous law) and began promoting non-violence, vegetarianism, and religious tolerance throughout his empire.

Ashoka ordered the carving of edicts on pillars and rocks across the Indian subcontinent. These inscriptions, written in Prakrit and other languages, proclaimed his policies of non-violence, social welfare, and religious harmony. They are the earliest deciphered written records from ancient India.

Ashoka convened the Third Buddhist Council at Pataliputra to resolve doctrinal disputes within the Buddhist monastic community. The council standardized the Buddhist canon (Tripitaka) and decided to send missionaries abroad, including to Sri Lanka and Southeast Asia.

Ashoka built thousands of stupas and monasteries across his empire, including the Great Stupa at Sanchi. These structures became centers of Buddhist worship and pilgrimage, spreading Buddhist art and architecture throughout Asia.

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.
