The 1920s in the United States were a time of political, economic, technological, and social improvement. New efforts were made for world peace, numerous inventions helped Americans, and life and work improved for many during this period of time, known as the “Roaring Twenties” because of how quickly things were moving and improving – all this contributed to the overall progress direction of the country.

Get an original essay Political improvement is exemplified by the Kellogg-Briand Pact of 1928, which was one of President Calvin Coolidge's efforts to increase isolationism in the United States and stay from wars (he had become president when Harding died in 1923, and was elected again in 1924). It was a treaty signed by fifteen nations who promised not to wage war against each other unless it was in self-defense (and unless the promise was broken, there would never be a legitimate war defense between the aforementioned countries). Many Americans supported this treaty because they thought that once war was outlawed, it would generally disappear. This had the effect of protecting peace in the United States, as it prevented war between the United States and all fifteen participating nations. The economy also improved dramatically during the Roaring Twenties. During this period, average annual per capita income increased by more than 35 percent: from $522 to $716, a dramatic improvement that helped citizens across the nation. This was aided by the fact that both Harding and Coolidge were not very strict about government regulation and businesses were allowed to grow and prosper unchecked, stimulating the economy to even higher levels. Improved technology was another important factor in the 1920s. The assembly line, a conveyor belt-like construction in which different parts were assembled at different times, was first used by Henry Ford for his automobiles, resulting in one Model T Ford leaving his factory every ten seconds. Electricity and coal became available to more people, meaning that machines such as electric vacuum cleaners, dishwashers, washing machines, sewing machines and others could make life easier across the country. Finally, social life improved dramatically for many groups of people. Young people began to rebel against their elders and their ideas, went to college and spent more time in school. New styles also took hold. The changes in style intrigued women, who began to have a new and stronger interest in life and were able to have more jobs in offices, factories and other professions. They were guaranteed the right to vote by the 19th Amendment and some were even elected governors such as Nellie Tayloe Ross in Wyoming, in 1924. African Americans also experienced improvements, as the NAACP worked to protect their constitutional rights and they gained more jobs . in the North. Please note: this is just an example.
