The Turkish traveler writer Evliya Çelebi mentions the impact of Cossack raids from Azak upon the territories of the Crimean Khanate. These raids ruined trade routes and severely depopulated many important regions. By the time Evliya Çelebi had arrived almost all the towns he visited were affected by the Cossack raids. In fact, the only place Evliya Çelebi considered safe from the Cossacks was the Ottoman fortress at Arabat.
