Spanish-American relations refer to the diplomatic, economic, and cultural interactions between Spain and the United States. These relations have evolved over centuries, beginning with early exploration and trade in the 15th and 16th centuries. The relationship became more complex during the Spanish-American War in 1898, which resulted in the U.S. gaining territories such as Puerto Rico, Guam, and the Philippines. In the 20th and 21st centuries, Spanish-American relations have focused on cooperation in areas like trade, tourism, and cultural exchange. Both countries are members of international organizations, fostering collaboration on global issues such as climate change and security.
