Congress of Breda fresh congress at Aix-la-Chapelle was arranged, where all warring states would participate, to offer formal approval to the agreement between Britain and France. The peace was formally concluded with the Treaty of Aix-la-Chapelle in 1748 in which all parties participated although the terms had already been agreed in advance by Britain and France at Breda. The terms proved deeply unsatisfactory to Maria Theresa of Austria who was outraged that Austria had lost Silesia and that the British had agreed so at Breda, without any Austrians being present. In the long run, that contributed to the breakdown of the Anglo-Austrian Alliance.
