Upon the death of magnate Stanisław Koniecpolski (March 1646), an advocate of fair treatment of Cossacks, his successor, Aleksander, redrew the maps of his possessions. He laid claim to Khmelnytsky's estate, claiming it as his. Trying to find protection from this grab by the powerful magnate, Khmelnytsky wrote numerous appeals and letters to different representatives of the Polish crown but to no avail. At the end of 1645 the Chyhyryn starosta Daniel Czapliński officially received authority from Koniecpolski to seize Khmelnytsky's Subotiv estate.
