Austria and France

The Franco-Austrian Alliance was a diplomatic and military alliance between France and Austria that was first established in 1756 following the First Treaty of Versailles which lasted for much of the remainder of the century until it was abandoned during the French Revolution.
Throughout the seventeenth and eighteenth centuries France and Austria had been enemies, repeatedly fighting wars against each other.In August 1756, Frederick the Great of Prussia, fearing that his country was about to be overrun and partitioned by its enemies, launched a preemptive strike against Austria’s ally Saxony which he succeeded in capturing. This triggered the declaration of the Seven Years War and Austria went to war with Prussia with France as an ally. The French Revolution destroyed the ties between the two states despite appeals by the French National Assembly for Austria to honor the Treaty of 1756.
