Page "Piri Reis" Paragraph 5

Today, based on the Ottoman archives, we know that his full name was " Hadji Ahmed Muhiddin Piri " and that he was born either in Gelibolu ( Gallipoli ) on the European part of the Ottoman Empire ( in present-day Turkish Thrace ), or in Karaman ( his father's birthplace ) in central Anatolia, then the capital of the Beylik of Karaman ( annexed by the Ottoman Empire in 1487 ).

The exact date of his birth is unknown.

The honorary and informal Islamic title Hadji ( Turkish: Hacı ) in Piri's ( Hadji Ahmed Muhiddin Piri ) and his father's ( Hadji Mehmed Piri ) names indicate that they had completed the Hajj ( Islamic pilgrimage ) by going to Mecca during the dedicated period of Hadjj and fulfilling the required rituals.
