Muawiyah I vs Yamagata Aritomo

Muawiyah I was appointed governor of Syria by Caliph Umar. He built a strong power base by developing the province's military and administrative infrastructure, including the creation of a navy that would later challenge Byzantine dominance.

Muawiyah launched naval expeditions against the Byzantine Empire, including the Battle of the Masts (655), where the Muslim fleet defeated the Byzantine navy. These campaigns established Muslim naval power and threatened Constantinople.

Muawiyah led the Syrian army against Caliph Ali at Siffin, demanding justice for Uthman's murder. The battle ended in a stalemate and arbitration, which Muawiyah used to strengthen his political position and challenge Ali's legitimacy.

After Ali's assassination, Muawiyah I established the Umayyad Caliphate, moving the capital from Medina to Damascus. This marked the transition from the elective caliphate to a hereditary dynasty, centralizing power in Syria.

Muawiyah I ordered a prolonged siege of Constantinople, using a large fleet and army. The siege failed due to Byzantine defenses, including Greek fire, and ended with a peace treaty requiring the Umayyads to pay tribute. It was a rare setback.

Muawiyah I designated his son Yazid as his successor, breaking the tradition of election and establishing hereditary succession. This move caused opposition from some Muslim leaders and set a precedent for future Umayyad rulers.
