Theodora's marriage is intended to cement her father's alliance with the rising Ottoman emirate and to prevent the Ottomans from giving their aid to the Empress-regent Anna of Savoy during the ongoing civil war.

Her parents and sisters escort her to Selymbria, where Orhan's representatives, including grandees of his court and a cavalry regiment, arrive on a fleet of thirty ships.

A ceremony is held at Selymbria, where Orhan's envoys receive her and escort her to the Ottoman lands in Bithynia, across the Marmara Sea, where the actual wedding takes place

Andrew had very soon been assassinated very soon in September 1345, and in the autumn of that year, Mézières had set out for the East in the French army.
