What action did both Suleiman the Magnificent

and Shah Abbas take?

Suleiman the Magnificent was an Ottoman emperor son of Sultan Selim I, who ruled several cities before succeeding his father (1520) in command of the empire. He began his reign with several campaigns against Christian states in the Mediterranean and central Europe, took Belgrade (1521), the island of Rhodes (1522) and defeated the Hungarian king Louis II (1526), who died in battle, ensuring his dominion over the Danube valley. He besieged Vienna (1529) and signed a truce with Archduke Fernando of Austria (1533). Invested against Persia, and conquered Iraq and several regions of eastern Anatolia.

Abas I the Great was shah of the Safavid Empire, successor to his father Mohammed Codabanda and predecessor of Safi. He ended the war he inherited against the Ottomans, granting territories to free himself to expel the Uzbek Turks from northeastern Persia
