There was a friendly relation between the Ottoman Empire and Poland. Dinyester River was forming the territory between two countries. Although a tension was emerged between the Ottoman Empire and Poland during the Ottoman-Austrian wars, peace was not violated. But, the Khan of Crimea who gained the cast of military union by the campaigns to Poland, was ignoring peace. Also, the Polish occupied the Hotin Castle that was dominated by Moldavia, and interfered the internal affairs of Moldavia (1617). Besides they continued to interfere in the internal affairs of Wallachia and Transilvania. Upon these events Sultan Osman decided to campaign Poland. Meanwhile, the forces commanded by Ozi Governor Iskender Pasha defeated the Polish army in Yas (20^th September 1620).

Sultan Osman II marched through Poland, on April of 1621. Poland was trying to organise a stronger army. With Austria’s assistance they extended their army. The Ottoman Army came to the fore of Hotin on 2^nd September 1620. The castle was besieged. In the battle the Polish army occupied the ottoman fronts and the yeniceris lost their courage and concentration. The Polish ambassadors declared that, they caused the war, and the Hotin Treaty was signed (20^th September 1621). According to the treaty; the Polish and the Ottomans would not attack each other’s territories and Poland would give 40.000 coins to the Crimea Khan as it had been before.
