The Treaty of Worms was a political alliance formed between Great Britain, Austria and the Kingdom of Sardinia, signed on 13 September 1743, during the War of the Austrian Succession. It was an ambitious piece of foreign policy on the part of the British government which sought to split the Emperor Charles VII, prince-elector of Bavaria, from French influence, whilst simultaneously resolving the differences between the Emperor, Queen Maria Theresa of Hungary and King Charles Emmanuel III of Sardinia.
