What were the main causes and consequences of the French involvement in the War of the Polish Succession?

The War of the Polish Succession (1733-1738) was a major conflict in Europe that involved several powers, including France, Austria, Russia, and Spain. The war was triggered by the death of Augustus II of Poland, which left the Polish throne vacant. The two main contenders for the throne were Augustus's son, Augustus III, who was supported by Russia and Austria, and Stanislaw I Leszczynski, who was supported by France. The French involvement in the war was driven by several factors, including their desire to expand their influence in Europe, their long-standing rivalry with Austria, and their wish to create a strong buffer state in Poland that would protect them from the Austrians and the Russians.

The war had several consequences for France. Firstly, it strained the country's finances, as France was already engaged in several other conflicts at the time. The cost of supporting the Polish cause, which included sending troops and money, put a significant strain on the French treasury. Secondly, the war damaged France's reputation in Europe, as it was seen as an aggressive power that was willing to risk war for its own interests. Finally, the war had a significant impact on the balance of power in Europe, as it led to the rise of Prussia as a major power and weakened the Austrian Habsburgs.
