Abbas I vs Tokugawa Ieyasu

Abbas I created a standing army of ghulams (military slaves) recruited from Christian subjects in the Caucasus, particularly Georgians and Armenians. This reduced reliance on the Qizilbash tribal forces, increased royal control, and modernized the military with firearms and artillery.

Abbas I moved the Safavid capital from Qazvin to Isfahan, transforming it into a magnificent city with grand architecture, including Naqsh-e Jahan Square, the Shah Mosque, and the Ali Qapu Palace. This relocation became a symbol of Safavid power and cultural flourishing.

Abbas I sent diplomatic missions to European courts, including those of Philip III of Spain, Rudolf II of the Holy Roman Empire, and Elizabeth I of England, seeking alliances against the Ottoman Empire. These missions opened sustained diplomatic and commercial exchanges between Safavid Persia and Europe.

Abbas I defeated an Ottoman army near Sufiyan, securing Safavid control over Azerbaijan and the Caucasus. This victory was part of the Ottoman-Safavid War of 1603-1618, which resulted in the recapture of Tabriz, Nakhchivan, and Yerevan from Ottoman occupation.

Abbas I, with support from the English East India Company, captured the island of Hormuz from Portuguese control. This ended Portuguese dominance in the Persian Gulf and opened direct trade routes for Safavid Persia with Europe, boosting the silk trade.

Abbas I captured Baghdad from the Ottoman Empire after a siege, restoring Safavid control over Iraq. This victory expanded Safavid territory and gave Abbas control over important Shi'a pilgrimage sites like Najaf and Karbala.

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.
