"The U.S. Constitution of 1787 helped advance the transition to modern democracy. It did this in a surprising way by purging many elements of early democracy that had existed in state constitutions as late as the 1780s. After 1787 representatives could no longer be bound by mandates or instructions, whereas this had been common in colonial assemblies as well as in early state assemblies. Likewise, elections would occur less frequently, whereas even after 1776, in state legislatures elections most often occurred annually. Individual states would also be compelled to accept central decisions with regard to taxation and defense. Unlike in early democracy, the Constitution allowed for the creation of a powerful central state bureaucracy, and it offered a form of political participation that was broad but also only episodic and that involved governance across a very large territory. We are still in the process of learning whether this experiment can work."
