Cause → Event → Consequence
Over half a century of Ottoman military pressure had steadily stripped the Byzantine Empire of its Anatolian territories. By 1354, Byzantium retained almost no possessions in Anatolia beyond the city of Philadelphia, leaving its European frontier exposed and its capacity to resist Ottoman expansion severely diminished.
In March 1354, Ottoman Turkish forces besieged and captured the fortress and peninsula of Gallipoli. The operation, known in Turkish as Gelibolu'nun Fethi, secured a permanent Ottoman presence on the European side of the straits, establishing their first significant territorial foothold on the continent.
Control of Gallipoli gave the Ottomans access to the Aegean and Marmara seas, enabling systematic expansion into the southern Balkans. This positioned them to advance further north toward the Serbian Empire and Hungary, fundamentally altering the balance of power in southeastern Europe for centuries to come.
