Fifty states of USA.

The success of the Revolution gave Americans the opportunity to give legal form to their ideals as expressed in the Declaration of Independence, and to remedy some of their grievances through state constitutions. As early as May 10, 1776, Congress had passed a resolution advising the colonies to form new governments "such as shall best conduce to the happiness and safety of their constituents." Some of them had already done so, and within a year after the Declaration of Independence, all but three had drawn up constitutions.
The new constitutions showed the impact of democratic ideas. None made any drastic break with the past, since all were built on the solid foundation of colonial experience and English practice. But each was also animated by the spirit of republicanism, an ideal that had long been praised by Enlightenment philosophers.
