The document provides an overview of the Progressive Era and American imperialism from the early 1900s through World War 1. Some key points:
- The Progressive Era saw reform efforts like protecting social welfare, promoting moral improvement, and trust-busting under presidents like Theodore Roosevelt.
- American imperialism grew due to factors like nationalism, social Darwinism, and the desire for foreign markets. This led to the annexation of Hawaii and war with Spain over Cuba.
- The Spanish-American War expanded U.S. territory to include Guam, Puerto Rico, and the Philippines as America took its first steps onto the global stage as a world power.
