The Vchynice family from the town of Vchynice was an Old Bohemian family. The first documented ancestor is Bohuslav ze Žernosek, mentioned in 1276, who had sons named “ze Vchynice”, according to the fortress and village near Lovosice. In the following years, their descendants split into several ancestral branches. The continuation of the Vchynice family from Vchynice was ensured by the branch of Jan Dlasek from Vchynice († 1521).
An important representative of the family was Radslav the Elder Vchynský of Vchynice and Tetov († 1619). Radslav is considered the founder of the extensive family fortune and an important representative of public life. During his life, he became one of the ten richest aristocrats of the Kingdom of Bohemia. On March 21, 1596, he was promoted by Emperor Rudolf II. to the lordly status. He completed his political career in 1611–1618 as the royal court master of the court of Emperor Matthias.
Another important representative of the family was Václav Norbert Oktavián Kinský (1642–1719). As his ancestors he held high positions at court, expanded the family’s property and over the years became the third largest feudal owner in Bohemia. In 1706, he established a part of his property, the so-called fideikomis, whose main center was the Chlumec estate.
After his death in 1719, his son František Ferdinand Kinský (I678-1741) took over most of the inheritance, including the Chlumec estate. In 1723 he was appointed the highest Czech court chancellor and court master, as well as Chief Huntsman of the Kingdom. Emperor Charles VI awarded him the Order of the Golden Fleece for his many years of service. The old Chlumec chateau could no longer fulfill the representational duties and prestige of the high-ranking family, so František Ferdinand had a new chateau built on the hill above the town of Chlumec nad Cidlinou. The designer was the leading Czech Baroque architect Jan Blažej Santini-Aichel. In 1723, Emperor Charles VI visited the chateau, in whose honor it was named Karlova Koruna (the Charles Crown).
