Sena Çakır is a Turkish performer credited as Gülşah Hatun in Mehmed: Fetihler Sultanı. Her character belongs to the palace-side story, where household relationships and loyalties add a personal layer to the larger historical events.
The ensemble lets the drama move between state decisions and the lives of people close to the court. This supporting role is part of that broader view of the period.
