The Peace of Vienna (often referred to as the First Treaty of Vienna) was a series of four treaties signed between 30 April 1725 and 5 November 1725 by the Habsburg Monarchy, the Holy Roman Empire (in accordance with Austria), and Bourbon Spain; the Russian Empire later joined the newly-found alliance in 1726. The signing of this treaty marks the founding of the Austro-Spanish Alliance and led the Fourth Anglo-Spanish War (1727-1729). This new alliance thereby removed Austria from the Quadruple Alliance. In addition to a formation of the new partnership, the Habsburgs relinquished all formal claims to the Spanish throne, while the Spanish removed their claims in the Southern Netherlands, and a number of other territories.
