Compared to his ancestors who ravaged the continents of Europe, Asia, and Africa, Abdul-Aziz Sultan could very much be considered an obedient child. Since ascending to the throne, he fostered good relations with neighboring states and exercised extreme caution in foreign diplomacy to avoid conflicts with European powers as much as possible.
Aside from kicking Russia while it was down during the Prusso-Russian war, Abdul-Aziz Sultan had not actively initiated any wars. He could be said to be one of the few pacifists among the Sultans throughout history.
Moreover, the last war was fraught with undercurrents; if not for the secret instigation by the great powers, Abdul-Aziz Sultan would have most likely chosen to be a spectator.
Of course, he became this "pacifist" not by choice. It was entirely because the surrounding enemies were too powerful; since they were unbeatable, he had to opt for peace.
