The Cossack raid on Istanbul (Constantinople) of 1615 was an attack on Istanbul by the Zaporozhian Cossacks, led by Hetman Petro Konashevych-Sahaidachny. Cossacks attacked the harbor of the city and burned it before returning to Ukraine. The success of this raid inspired the Tutora campaign of 1620 and the Khotyn campaign of 1621.[1]
