Karaca Ahmet Sultan is a semi-legendary saint of the Khorasan dervishes (abdalân-ı Rûm) tradition, held to have been active in the fourteenth-century Islamization of Anatolia. No fixed date of death is recorded in the sources, and traditional accounts link him to the era of Orhan Gazi. Numerous tombs and stations (makam) are attributed to him, and scholarly debate continues over his identity and true burial place between Üsküdar and Manisa/Akhisar; in this respect the Üsküdar site is largely regarded as a station (makam). The extensive Karacaahmet Cemetery in Üsküdar is named after this saint, and his tomb possesses a deep-rooted tradition of visitation.
