Which treaty, signed in 1713, ended the War of Spanish Succession and granted trade privileges to Britain?

The Treaty of Utrecht, signed in 1713, effectively concluded the War of the Spanish Succession, which had significant ramifications for European power dynamics. This conflict arose from concerns regarding the unification of the Spanish and French thrones under a single ruler, which many European powers saw as a threat to the balance of power.

One of the pivotal outcomes of the Treaty of Utrecht was that it not only ceased hostilities but also delineated the territorial and governance changes resulting from the war. Importantly, the treaty conferred several trade privileges to Britain, including significant access to Spanish territories and the right to trade with the Spanish colonies in the Americas. This marked a notable expansion of British influence and mercantile power.

In contrast, the other treaties mentioned do not relate to the War of the Spanish Succession or the specific context of British trade interests. For example, the Treaty of Guadalupe Hidalgo ended the Mexican-American War, the Camp David Accords pertain to peace between Egypt and Israel, and the Pact of Mutual Assistance is often associated with the Soviet bloc during the Cold War and not with early 18th-century European conflicts. Thus, the Treaty of Utrecht stands out as the correct answer in the context of the question asked.
