Sahaidachny returned to Zaporizhia, and did not only become a kosh otaman, but was also the Hetman of Ukraine. (Another source claims that in 1621 he was a colonel of the Commonwealth Registered Cossacks regiment). In order to avoid conflict with the Poles, Sahaidachny agreed to limit the Cossack register to 3,000 men, the remainder were regarded as peasants ("kholopy"). He also banned unauthorized Cossack sea raids to Turkey and the king gave Sahaidachny the right to be called an elder of the Cossacks("starshina").
