The series begins in the Sultan’s 20th year in power. The Hejaz Railway is a large project that they are planning. However, the Sultan’s brother-in-law, Mahmud Pasha, as well as the British and Theodor Herzl, are attempting to derail this project. Bidar Sultan and Seniha Sultan’s rivalry in the harem, on the other hand, extends to their family. In addition, the Sultan’s brother Murad’s daughters visit the palace.
Hatice Sultan, his eldest daughter, falls in love with Kemalettin Pasha and plans to marry him, while Naime Sultan, the Sultan’s daughter, also falls in love with Kemalettin and tries to win his heart, eventually becoming ill.
Hatice Sultan, in her love for Naime, pretends that Kemalettin loves Naime by giving a letter written by Kemalettin to Hatice. Seniha Sultan’s husband, Mahmud Pasha, heaps slander upon slander on Mehmed Pasha, Bidar Sultan’s brother, eventually driving him into exile.
Abdülkadir, the Sultan’s son, is consistently manipulated by Mahmud Pasha and his son Sabahattin, and while attempting to ruin their game, he ends up in a burning room with his mother at the end of the season, which was started by Esma, a traitor servant girl, on Sabahattin’s order. The Payitaht Abdulhamid Season 1 concludes with Greece attacking Ottoman territory and the Ottoman Empire declaring war on Greece.
