<span>One of the most important accomplishments of the Progressive Era was the Nineteenth Amendment of the Constitution. This amendment gave both sexes the right to vote (women could now vote). Voting can affect family life. One example of this was the temperance movement. It promoted the practice of never drinking alcohol.

The US was extremely involved in foreign affairs after the Spanish American War. This victory in helping liberate Cuba from Spanish control resulted in the creation of the "American empire." Thanks to this war, the US gained control of Guam, Puerto Rico, and the Philippines. These newly acquired territories were excellent places to send American goods, as businesses were producing more goods than ever thanks to the rapid industrialization taking place in American society.
The US continued to spread its power and influence by annexing other places, like Hawaii. Along with this, the US desired consistent trade with other countries, hence why they introduced the idea of the Open Door Policy in China.
