The Ottoman geography possessed iron, silver, gold, copper, tin, and lead mines in the 16th century, with iron being one of the more important. However, research on mines in the Ottoman Empire is about something other than the iron mines. For this reason, this research will discuss the production, extraction, and use of iron products before the Industrial Revolution. One of the critical centers where the Ottoman Empire was supplied with iron was Samakov, which was affiliated with Sofia Sanjak. Samakov was conquered in 1371 by Lala Şahin Pasha, the governor of Rumelia, during the reign of Murad I. The iron extracted from Samakov was pro-duced in raw and finished products. The iron extracted from the region was used in military areas such as shipyards and artillery and in architectural sites such as mosques, bridges, and castles. The iron obtained from the iron deposits was mel-ted in furnaces known as vigne in the Ottoman official records. This iron was also processed in iron forging workshops known as samakov. Iron, in its raw and finished products, as sent by land or sea to Istanbul, the state’s center. This delivered iron was then distributed to military facilities and other places where it was needed. When transporting iron by land, carts were pulled by beasts of burden, such as oxen or ca-mels. Samakov maintained its status as one of the centers where the state met its iron needs until the last period of the Ottoman Empire. This research references the archive books and documents related to the subject in the Ottoman Archive section of the Presidency of the Republic of Türkiye Directorate of State Archives.
