Progressives continued to make strides during the war. Discuss the various Progressive accomplishments between 1916 and 1920. Comment on why the movement declined by 1920.

During the years between 1916 and 1920, the Progressive movement in the United States achieved several significant accomplishments. One of the most notable achievements was the passage of the 19th Amendment in 1920, which granted women the right to vote. This was a major victory for the suffragist movement and a significant step forward for gender equality in the United States.

Additionally, the Progressive movement made strides in labor reform during this time period. The Adamson Act of 1916 established an eight-hour workday for railroad workers, setting a precedent for labor rights and protections. The Keating-Owen Child Labor Act of 1916 also marked a significant victory for Progressives, as it prohibited the interstate sale of goods produced by child labor.

The Progressive movement also made progress in the realm of conservation and environmental protection. President Woodrow Wilson signed the National Park Service Organic Act in 1916, which established the National Park Service and aimed to preserve and protect the country's natural landscapes for future generations.

Despite these accomplishments, the Progressive movement began to decline by 1920 for several reasons. The United States' entry into World War I in 1917 shifted the nation's focus away from domestic reform and towards the war effort. Additionally, the Red Scare and anti-radical sentiment that followed the war led to a crackdown on progressive and leftist organizations, stifling the movement's momentum.

Furthermore, the passage of the 18th Amendment, which established Prohibition in 1919, divided the Progressive movement and diverted attention and resources away from other reform efforts. The internal divisions and external pressures ultimately contributed to the decline of the Progressive movement by 1920.
