in the list of Anglo-Spanish agreements renewed in the Preliminaries to the treaty. When he tried to amend the final version, the Spanish refused to approve it, threatening the lucrative import and export trade between the two countries. Since it was equally valuable to the Spanish, they later agreed terms in the October 1750 Treaty of Madrid, but it was another source of popular dissatisfaction with the treaty. Austrian resentment of British 'disloyalty' was mirrored in London; many questioned the value of the financial subsidies paid to Vienna, and suggested Prussia as a more suitable ally. In the 1752 Treaty of Aranjuez, Austria, Spain and Sardinia agreed to respect each other's boundaries in Italy, ending conflict in this region for nearly fifty years, and allowing Maria Theresa to focus on Germany. Her determination to regain Silesia, combined with a feeling the Treaty had left many issues unresolved, meant that it was seen as an armistice, not a peace. The treaty marked the end of First Carnatic War (1746–1748). References Sources Bibliography Olson, J.S.; Shadle, R. Historical Dictionary of the British Empire. Greenwood Press. (1996): 1095–1099. .
