Final answer:
The Pact of Paris marked the end of the Spanish-American War and established the United States control over Puerto Rico, Guam, and the Philippines, signaling the rise of a new American empire.
Step-by-step explanation:
The Pact of Paris, also known as the Treaty of Paris signed on December 10, 1898, had significant political repercussions for the United States and global politics. It marked the end of the Spanish-American War and resulted in Spain ceding control of its imperial possessions such as Puerto Rico, Guam, and the Philippines to the United States, in exchange for a payment of $20 million. This expansion of American territory signified the emergence of a new American empire and played a pivotal role in shaping the nation's foreign policy and imperial ambitions at the threshold of the 20th century.
