Charles Louis Auguste Fouquet, duc de Belle-Isle was a French general and statesman.

The War of the Polish Succession was a major European conflict sparked by a civil war in the Polish–Lithuanian Commonwealth over the succession to Augustus II the Strong, which the other European powers widened in pursuit of their own national interests. France and Spain, the two Bourbon powers, tested the power of the Austrian Habsburgs in Western Europe, as did the Kingdom of Prussia, whilst Saxony and Russia mobilized to support the eventual victor. The fighting in Poland–Lithuania resulted in the accession of Augustus III, who in addition to Russia and Saxony, was politically supported by the Habsburgs.
