Abbas I vs Suleiman I

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.

Suleiman I led a massive Ottoman army and fleet to besiege the island of Rhodes, held by the Knights Hospitaller. After a six-month siege, the knights surrendered and were allowed to leave. This victory secured Ottoman control over the eastern Mediterranean.

Suleiman I led an Ottoman army to besiege Vienna, the capital of the Habsburg Empire. The siege failed due to supply problems and the onset of winter. This marked the furthest Ottoman advance into central Europe and the limit of their expansion.

Suleiman I oversaw the codification of Ottoman law, known as the Kanun. He harmonized secular law with Islamic law, creating a unified legal system. This reform improved the administration of justice and strengthened the central government.

Suleiman I ordered the execution of his grand vizier and close friend Ibrahim Pasha. Ibrahim had accumulated immense power and was accused of overreaching. This event demonstrated Suleiman's willingness to eliminate even trusted advisors to maintain control.

The Ottoman fleet under Hayreddin Barbarossa defeated a combined Christian fleet at Preveza. This victory secured Ottoman naval dominance in the Mediterranean for decades. It allowed the Ottomans to control trade routes and raid coastal areas.
