Abbas I vs Alexios I Komnenos

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.

Alexios I Komnenos was defeated by the Norman army under Robert Guiscard at Dyrrhachium. The Byzantine forces were routed, and Alexios barely escaped. This loss allowed the Normans to occupy much of the western Balkans, though Alexios later recovered some territory.

Alexios I implemented a series of reforms to restore Byzantine power. He reorganized the army by relying more on foreign mercenaries, reformed the currency (the hyperpyron), and granted tax exemptions to the Church. These measures stabilized the empire after decades of decline.

Alexios I sent envoys to Pope Urban II at the Council of Piacenza, requesting military aid against the Seljuk Turks. This appeal contributed to Urban's call for the First Crusade at the Council of Clermont later that year, initiating the Crusader movement.

Alexios I cooperated with the Crusader army to besiege and capture Nicaea from the Seljuk Turks. The city was surrendered to Byzantine control, and Alexios used the Crusaders to recover key territories in Anatolia, though tensions later arose over land claims.
