depiction of Charles's coronation as Holy Roman Emperor (1742) coin of Charles VII, dated 1743 In continuance of the policy of his father, Charles aspired to an even higher rank. As son-in-law of
Emperor Joseph I, Charles rejected the
Pragmatic Sanction of 1713 and claimed the German territories of the Habsburg dynasty against
Maria Theresa, daughter of
Emperor Charles VI, in 1740. By the
Treaty of Nymphenburg, which was concluded in July 1741, Charles became allied with
France and
Spain against Austria. During the
War of the Austrian Succession, Charles invaded
Upper Austria in 1741 and planned to conquer
Vienna, but his allied French troops under the
Duc de Belle-Isle were instead redirected to
Bohemia, capturing
Prague in November 1741. That meant that Charles was crowned
king of Bohemia in Prague on 19 December 1741, when the Habsburgs had not yet been defeated. He was
unanimously elected king of Germany on 24 January 1742 and became
Holy Roman emperor upon his coronation on 12 February 1742. His brother
Clement August, the
archbishop-elector of Cologne, generally sided with the Habsburg-Lorraine faction in the disputes over the Habsburg succession but cast his vote for him and personally crowned him emperor at
Frankfurt. King
George II of Great Britain, as the elector of
Hanover, also voted to install Charles as emperor even though both
Britain and Hanover were allied with Austria in the ongoing war. Charles VII was the second
Wittelsbach emperor after
Louis IV and the first Wittelsbach king of Germany since the reign of
Rupert. Shortly after his coronation, most of Charles's territories were overrun by the Austrians, and
Bavaria was occupied by the troops of Maria Theresa. The Emperor fled Munich and resided for almost three years in the
Palais Barckhaus in
Frankfurt. Most of Bohemia was lost in December 1742, when the Austrians allowed the French under the Duc de Belle-Isle and the
Duc de Broglie an honourable capitulation. Charles was mocked as an emperor who neither controlled his own realm nor was in effective control of the empire itself, but the institution of the Holy Roman emperor had largely become symbolic in nature and powerless by then. A popular
Latin saying about him was
et caesar et nihil, meaning "both emperor and nothing", a word play on
aut caesar aut nihil, meaning "either emperor or nothing". Bavarian General Ignaz Felix, Count of Törring-Jettenbach was compared to a drum, as people "heard about him only when he was beaten". Charles VII tried to boost his prestige from Frankfurt with numerous legal acts, such as granting imperial privilege to the
University of Erlangen in 1743 and creating several new imperial nobles.
Charles Eugene, Duke of Württemberg, was declared to be of full age in 1744, ahead of time.
Alexander Ferdinand, 3rd Prince of Thurn and Taxis served as Principal Commissioner for Charles VII at the
Perpetual Diet of Regensburg and in 1744 the
Thurn und Taxis dynasty were appointed the hereditary Postmasters General of the Imperial
Reichspost. Charles' brother Klemens August was more pro-Austrian, and Charles' son and successor
Maximilian III Joseph made peace with Austria. With the
Treaty of Füssen, Austria recognized the legitimacy of Charles's election as Holy Roman Emperor. ==Cultural legacy==
