He was the younger son of nobleman Stanisław Kmita and Katarzyna Tarnowska. He was also the grandson of Jan Kmita and brother in law to Jan Herburt. An educated person, Piotr Kmita gathered a considerable amount of books at his castle in Wiśnicz. He was also an ardent supporter of Erasmus of Rotterdam. He spent his youth at the court of Emperor Maximilian I, where he distinguished himself for his military valor and humanistic refinement. He fought the Tatars in the Battle of Wisniowiec and the Russians in the Battle of Orsha, and in 1520 he took part in the war against the Teutonic Knights. In 1518, he became Marshal of the Crown Court and in 1522 was a Polish envoy to the Imperial Diet at Nuremberg. In 1524 he defeated the Turkish army in Terebovl. In 1520 he received from Sigismund I the Old the right to collect tributes on the roads to Ustjanowa Dolna. Kmita was one of the most trusted followers of Queen Bona Sforza for the establishment of national factions in Hungary against the Habsburgs and the fight of the nobility for privileges at the end of Sigismund Augustus reign. He traveled to Hungary in support of John Zápolya, and entered the so-called triumvirate at Bőny, alongside Piotr Gamrat and Andrzej Krzycki.

In 1523 he received from Emperor Charles V the title of Count of Wiśnicz. He was a patron of culture, his court in Wiśnicz was one of the finest centers of Polish Renaissance, gathering the era of the best minds of lawyers, writers and poets.
