Why was there a need to move from the rule of dynasties to nationalism?

Explanation:

Nationalism holds that each nation should govern itself, free from outside interference (self-determination), that a nation is a natural and ideal basis for a polity and that the nation is the only rightful source of political power (popular sovereignty).

- "a new era of american politics began with jackson's election in 1828, but it also completed a grand social experiment begun by the american revolution. nevertheless, jacksonian democracy represented a provocative blending of the best and worst qualities of american society."
