After 1504, Hizir and Oruc engaged in a struggle for dominance against Spain, Genoa and France in the Mediterranean, and declared victory.
Taking the reign of Algeria in 1516, Hizir later offered his land to the Ottomans with a delegation sent to Selim I. Algeria became an Ottoman territory with this move.
He maintained the security of sea routes by ending the Venetian hegemony in the eastern Mediterranean and the Aegean.
With the victory of Preveze War against the Crusaders, he enabled the Turkish sovereignty in the central Mediterranean after the eastern Mediterranean.
During his term as admiral, Ottoman navy peaked in power.
He opened navy schools and his teachings guided many Ottoman sailors and commanders even centuries after his demise.
Barbaros passed away on July 4, 1546 in Besiktas, Istanbul.
Ottomans announced his death at 76 with a statement saying "the leader of the sea is dead".
"Barbaros was an admiral harmonizing the navy. He was experienced like an architect and engineer of ship. There are approaches to underestimate him by calling him a 'pirate', but this is about not knowing the Ottomans well," Idris Bostan, a history professor at Istanbul University, told Anadolu Agency.
"Barbaros participated in many operations in the Mediterranean. He knew all the Mediterranean ships because he saw them occasionally at the coast of Algeria, examined them and adapted them to his forces," he added.
