Campaigns of the Cossacks of Dmitry Vyshnevetsky to Achi-Kale , Akkerman and Islam-Kermen
The Cossack raid on Istanbul led by on the capital of the Ottoman Empire as a part of the Cossack Naval Campaigns and the OttomanâÂÂPolish War (1620âÂÂ1621).
In 1620 relations between the Ottoman Empire and the Polish-Lithuanian Commonwealth were rapidly deteriorating due to frequent raids from Cossacks. The Ottomans stated that they would break their peace agreement and declare war against Poland if they did not stop the Cossack raids.
The Ottomans promised to abandon these plans if, within four months, the Commonwealth destroyed the Cossacks. Although the Polish ambassador in Istanbul agreed, negotiations soured as the Ottoman ambassador was treated with disrespect. Thus, the Ottomans decided to end the Cossack raids themselves and proceeded to build a string of fortresses in southern Ukraine as preparation. However, the Cossacks had already decided to attack Turkey. Having learned about this, the Polish ambassador immediately escaped from Istanbul. The result of the raid was a Cossack victory.
The Cossacks then raided Varna on the Bulgarian coast, then proceeded to raid the Crimean city of Perekop. The cities were completely looted.
The raid formed the pretext for the Battle of Cecora (1620).
