Konstanty Korniakt z Białobok

Konstanty Korniakt of Białobok or Konstantyn Franciszek Korniakt (1582-1624) was a Polish nobleman and soldier, the son of the noble Polish merchant Konstanty Korniakt (1520-1603) of Crete. by which time he was the wealthiest inhabitant of Lviv, and one of the greatest patrons of Lviv Renaissance architecture.

Konstantyn Franciszek had five siblings: Aleksander, Michal, Anna (m. Jan Tarnowski), Zofia (m. Abraham Herburt), and Katarzyna (m. Aleksander Chodkiewicz).

Korniakt established his residence and family stronghold in the village of Bialoboki near Przeworsk. He assumed the name "Konstanty Korniakt of Białobok" and by 1608 had built a small castle on a hill on the site of a former stronghold. The new castle was constructed of brick on a rectangular plan and was surrounded by a moat and swamps and could only be accessed via a drawbridge. The interiors were beautifully decorated and equally well equipped. The floors were made of white stone, as were the sides of the castle. This mortgage had been assumed by Stanisław Stadnicki, "the devil of Łańcut", who had long contested the debt in the royal court. Stadnicki's debt had increased by another 30,000 zlotys for bail after he was sentenced for failure to appear in royal court. Konstantyn Korniakt of Białoboki died from wounds during this invasion as a defender of the Polish lands. He was buried in the Dominican church in Przemyśl. Although the Tatars captured most of the local population as jasyr, they were later intercepted and dealt a crushing defeat at the Battle of Martynów.

When he died Konstanty Korniakt of Białobok left the majority of his estates in the Przemyśl region to his daughter Anna and son-in-law Mikołaj Ossoliński. This included 29 villages and one city including the key of Rybotycze, the castle near Przemyśl, and the properties of Husaków and Miźnice. Rybotycze became the main residence from which Mikołaj made trips to the surrounding area and maintained a regular army there, recruited from the surrounding villages.

Konstanty's eldest son, Karol Franciszek Korniakt owned 11 villages in the Przemyśl region with his base at Białoboki. In the summer of 1630 Karol enrolled at the Jagiellonian University in Kraków and traveled extensively (Germany, Italy, France, Spain, England, Belgium, Holland). He studied military affairs and languages, notably at the University of Graz in Austria, and at University of Padua in Italy (1639). Karol participated in the Polish campaigns and battles and fought in many wars. He financed companies during the Khmelnytsky Uprising (1648-1657). He commanded his own company at the Siege of Zbarazh in 1649, and the Battle of Berestechko in 1651.
