Historically, the first official plan for the creation of Cossack formations as a border service was brought to the State Council of the Grand Duchy of Lithuania in 1524 by Semen Polozovic and Kristof Kmitic. However, due to the lack of funds, the idea was not realized. The starosta of Cherkasy, Ostap Dashkevych, revived the idea at the 1533 council in Piotrków Trybunalski. Dashkevych tried to show that in order to protect the borders beyond the Dnieper it would be necessary to maintain an army of 2,000 soldiers and several hundred cavalrymen. He pointed out the importance of establishing forts on the river's islands to keep Tatar raids in check. On July 21, 1541 the King of Poland, Sigismund I the Old, issued an edict to the starosta of Cherkasy, Andrei Glebovich Pronsky , in which he strictly warned Pronsky to control the Cossack raids against Tatar uluses. With the start of the Livonian War in the 16th century, the voivode of Kiev, Konstanty Wasyl Ostrogski, and the starosta of Cherkasy, Alexander Wisnowecki, recruited Cossacks to their armies, while in 1568 King Sigismund II Augustus sent a proposition to the Zaporizhian Sich to join his foreign campaign and sign up for royal service. Sigismund II Augustus decreed the formation of registered Cossacks on June 5, 1572 when the King confirmed the orders of Great Crown Hetman Jerzy Jazłowiecki, the voivode of Podole and Ruthenia, for state service. The first Hetman of the Registered Cossacks and court marshal was Jan Badowski. The registered Cossacks were the only military Cossack formation recognized by the Polish-Lithuanian Commonwealth.
