Dymitr was born around 1340 as the son of Piotr of Klecia (Piotr z Klecia), starost of Zhydachiv, member of the Korczak family (using the Korczak coat of arms) and owner of the village of Klecie.
He was one of the wealthiest magnates of his era, and a mentor and adviser to Queen Jadwiga of Poland. Around that time Dymitr converted from Orthodox to Catholic faith. In 1364, at the court of Casimir III the Great (last king of the Piast dynasty) he became the Court Treasurer, a title he would held in the years 1364–1370 (the year of Casimir"s death) and again in the years of 1377–1391.
As a trusted advisor to the King he was a signatory to the Acting of Union of Horodlo of 1413 and he signed peace in Brest Kujawski, on December 31, 1435.
Dymitr would be one of the most notable supporters of Louis in Poland, possibly even his friend, and took part in important diplomatic missions on behalf of Louis. Dymitr became a mentor and adviser of the Louis daughter and Polish queen Jadwiga of Poland.
