Josef was primaraly a general and was very successful in that line of work. In 1745 he was made Generalissimo in Italy and in 1753 was made General Chief Commander in Hungary. In one of the greatest achievements of his career he reorganised the AustrianArtillary, partly out of his own pocket. From 1735 to 1736 he was Imperial Envoy to Berlin and he was Ambassador to Paris between 1738 to 1741. In 1760 he escorted the future bride of Josef II to Vienna.
Josef managed to rule Liechtenstein three times, firstly in his own right from 1712-18. The second time he ruled as heir to Josef Johann Adam between 1732-45 and the third time as representative of the House of Lichtenstein from 1748-72.
JosefWenzel (born 1696, died 1772) enjoyed to a high degree the range of talents characteristic of a Baroque aristocrat.
From 1735 to 1740, Joseph Wenzel undertook diplomatic missions and represented the Emperor as an emissary and ambassador in Berlin and Paris.
In 1739, the Prince, who had been awarded the Golden Fleece, was appointed general of the cavalry; in 1744, he received general directorship of the artillery in recognition of his skills; and finally, in 1745, he received the supreme command of the Austrian army in Italy.
