Born in Milan, in what is now northern Italy, he was the son of Prince Emanuel of Liechtenstein and Maria Anna Antonia, Countess of Dietrichstein-Weichselstädt, Baroness zu Hollenburg und Finkenstein (10 September 1706 – 7 June 1777).
He was a nephew of Joseph Wenzel I, whom he succeeded on 10 February 1772. Franz Joseph had been recognised heir to Liechtenstein since 1723, when his uncle"s only son had died. Joseph Wenzel took Franz Joseph under his wing and Franz Joseph accompanied him in a campaign in Northern Italy, fighting with Wenzel at the Battle of Piacenza.
The battle was a victory for the Holy Roman Empire, of which Liechtenstein was a part.
In 1763, Franz Josef traveled on behalf of the Emperor to Spain, to bring the bride of Archduke Leopold a picture of the Archduke. Once Franz Joseph became Prince of Liechtenstein, he showed great interest in its economic problems and the ever-increasing Liechtenstein art collection.
He died in Metz in 1781.
Franz Josef married Marie Leopoldine Gräfinance von Sternberg (Vienna, 11 December 1733 – Feldsberg, 27 June 1809), a member of the Bohemian nobility, on 6 July 1750 in Valtice or Feldsberg.
