The 1920s were a period of dramatic changes. More than half of all Americans now lived in cities and the growing affordability of the automobile made people more mobile than ever. Although the decade was known as the era of the Charleston dance craze, jazz, and flapper fashions, in many respects it was also quite conservative.

South American countries fell into dictatorships becuase they had the same conditions which supported dictators in Europe. Economic instability led to loss of faith in democractic institution. The military was more efficient than a legislature.

The United States had a unique experience in that it had ample time and space to tackle the challenges it faced including a bloody civil war, expanding across the continent and giving equality to Blacks. There was no direct intervention by foriegn powers in American affairs. Moreover the founding father of United States had set up the tradition of a strong legislature. George Washington, the first American president, voluntarily gave up his military commission back to Congress after the Revolutionary War was over. He also left the Presidential office after two terms thereby creating a strong tradition.
