Following the Smolensk campaign, the Commonwealth was threatened by another attack by the Ottoman Empire. During the wars against Ottomans in 1633–1634 Władysław moved the Commonwealth army south of the Muscovy border, where under the command of hetman Stanisław Koniecpolski it forced the Turks to renew a peace treaty. In the resulting treaty, both countries agreed again to curb the border raids by Cossacks and the Tatars, and the Ottomans confirmed that the Commonwealth to be an independent power, and had not to pay tribute to the Empire.
