Since the beginning of the 20th century, numerous major revolutionary movements have occurred in the United States, contributing to a broad spectrum of changes, from the daily lives of American people, to a more complete vision of the world and of themselves, up to the national economic system. These movements had reached their peak in the 1920s, known as the “Roaring Twenties.” Along with the changes, conflicts and tensions between adapting to new attitudes and preserving traditional values ​​rapidly grew. The emergence of the “New Morality,” the development of Science and Technology, and changes in the economy were the three most significant winds of change that led to enormous tension in the 1920s, manifesting in distinct ways. The 1920s were represented by a change in cultural values. On the one hand, minorities and vulnerable social groups gained greater equality and social recognition, and on the other hand, people who held traditional values, fearing this sudden change, formed their own groups to resist it, the most notable of which was the Ku Klux Klan. . When the Nineteenth Amendment to the United States Constitution was ratified on August 18, 1920, American women finally gained suffrage, the legal right to vote. Once this was achieved, over the next decade, American women stepped forward and acquired even more important roles in society. The feminist ideal known as the New Woman was popular in the 1920s. Symbolized by an image of practically dressed women, living independently and freely, it manifested sexual liberation and the coeducational system. Flappers, free-thinking young women, easygoing ways, new fashions and... middle of paper... from culture to industry, the world's post-war overproduction of crops made this condition even worse. As there was too much supply and little demand, agricultural price levels dropped significantly and farmers faced the problem of low income. Coupled with the flawed credit system, the economy failed to maintain the fake growth trend for long. The market system finally collapsed in late 1929, leading to the Great Depression in the 1930s. In the 1920s, all of these enormous social, cultural, and economic changes caused great tensions between traditionalists and modernists, and the "Roaring Twenties" manifested all of these radical changes and conflicts in a variety of corresponding ways. Some of these were limited features of the time, while others would last for a relatively long period of time in American society.
