The War of the Austrian Succession, 1740 to 1748, was a conflict between the European great powers, fought primarily in Europe, the Atlantic Ocean and Mediterranean Sea. Related conflicts include King George's War, the War of Jenkins' Ear, the First Carnatic War, and the First and Second Silesian Wars.
Its immediate cause was the right of Maria Theresa to inherit Austria. This was challenged by a coalition between France, Prussia, and Bavaria, while Maria Theresa was backed by Great Britain, the Dutch Republic, and Hanover, collectively known as the Pragmatic Allies. The conflict later drew in other participants, including Spain, Savoy, Saxony, Sweden, and Russia.
Fighting began when Prussia occupied the wealthy Austrian province of Silesia in December 1740.
