The Progressive Era was a period of intense social and political reform in the United States, lasting from the late 19th century to the early 20th century. It sought to address social and economic problems caused by industrialization and rapid urbanization during the Gilded Age.

Now, to understand the changes brought upon by the Progressive Era, there are several steps you can take:

1. Research primary sources: Start by exploring primary sources like newspaper articles, journals, letters, speeches, and government reports from that time period. These sources can offer valuable firsthand accounts of the changes that occurred.

2. Examine key legislation: Look into the significant laws and regulations enacted during the Progressive Era. Some of the key pieces of legislation include the Pure Food and Drug Act, the Sherman Antitrust Act, the Clayton Antitrust Act, and the Federal Reserve Act. These laws aimed to improve public health, regulate business practices, and create a more stable economy.

3. Consider key reformers and their ideologies: Study the influential figures of the Progressive Era, such as Theodore Roosevelt, Woodrow Wilson, Jane Addams, and Ida B. Wells. Understanding their ideas and goals can provide insights into the changes they advocated for.

4. Analyze societal reforms: The Progressive Era witnessed various reforms, including the push for women's suffrage, the temperance movement, urban planning reforms, labor rights, and the establishment of child labor laws. Examining these reforms helps understand the extent of the changes that occurred.

5. Examine the impact on society: Consider the impact of the Progressive Era on different groups within society. For example, examine how labor unions gained strength and workers' conditions improved, or how women fought for their rights and gained the right to vote.

By following these steps, you can gain a comprehensive understanding of the changes brought upon by the Progressive Era and how they shaped American society.
