Turkish Bektashi dervish whose türbe (tomb) in Buda (part of present-day Budapest) became a Muslim place of pilgrimage.

Gül Baba arrived in Hungary in 1541 in the company of Süleyman I. According to 17th-century Turkish traveler and writer Evliya Çelebi, Baba died in Buda during the Turkish siege of the city. His coffin, as legend has it, was carried by Süleyman I himself. In 1543–48 the third pasha of Buda had a tomb built on Baba's grave.

Many details of Baba's life are based on legend. Even his name is the subject of debate. The most common modern interpretation of it is “Father of the Roses” (gül, “rose”; baba, “father”). Another theory is that he was originally called Kel (“Bald”) Baba, which only after his death became Gül when his tomb was covered with roses. Others believe that during religious ceremonies Baba was capable of kissing a red-hot iron, known as a “gül” in the dervish community. Finally, some believe that the dervishes called all of their leaders Gül Baba.
