Some historical documents and writings indicate that Fath Ali Shah Qajar, on the occasion of the 34th birthday of his son, Suleyman Mirza, established this palace as his summer residence and put its name on it. Others believe because Mohammad Ali Mirza Dolatshah, the eldest son of Fath Ali Shah, was dissatisfied with his father's decision to crown his brother Abbas Mirza. He decided to show himself, Suleiman Pasha summoned the governor of Baghdad and defeated him. He presented the great booty he gained from this war to his father, and Fath Ali Shah built the Karaj Sulaimaniyah Palace with this money to commemorate his son's victory.
