A colonizing dervish-sheikh active in the early 15th-century conquest and settlement of the Ordu region who, alongside the frontier-warrior Sevdeş Bey, founded a lodge and Friday mosque around Ulubey and led the Türkmen transition to settled life. The 1455 cadastral survey records the 'endowment of Şeyh Abdullah's lodge'; Şeyhler village is named after his sheikh sons. The present tomb is a renewed structure within the old cemetery.
