Joseph I Adam Prince of Schwarzenberg (15 December 1722,
Vienna – 17 February 1782, Vienna), 4th Prince of Schwarzenberg, was a German-Bohemian nobleman.
When he was 10, his father was killed in a hunting accident and he nominally succeeded his father and became the 4th Prince of Schwarzenberg and a Knight in the
Order of the Golden Fleece. He was K.u.K. Chamberlain, Geheimrat,
Obersthofmeister of Empress Maria Theresa and, finally, Staats- und Konferenzminister.
Joseph I of Schwarzenberg married on 22 August 1741 in Mariaschein near
Teplice, Maria Theresia von und zu Liechtenstein (28 December 1721 - 19 January 1753), the daughter of
Joseph Johann Adam, Prince of Liechtenstein and Maria Anna von Oettingen-Spielberg. Soon afterwards he and his wife built the church in
Postelberg, out of gratitude for the birth of an heir. In 1767 Joseph I bought the
Neuschloss estate.
On 5 December 1746 for Bohemia and on 8 December 1746 for the Holy Roman Empire, Joseph I of Schwarzenberg received the prince's diploma, extended to the effect that all marital male and female descendants were allowed to use the title “prince” or “princess” and was thus raised to the rank of imperial prince and the status of a Bohemian prince.
