... But I have a problem with your answer.
Democracy is a concept that began in Athens, meaning the citizens have the power to govern themselves, as opposed to having no say in government and being under the authority of one or a few people who have the power to govern over all.
Republic is a concept that began in Rome I believe. It is democracy but not direct democracy as was Athens. Instead of direct democracy, it is representative democracy.
Democracy and republic refer to concepts and a set of values, not the form of government. What is the word for quibbling over the meaning of a word? I don't mean to be picky, but I think understanding the history of democracy and republic concepts and implementation is vitally important, and using the words without a fully understanding of their meaning invites what happened to Germany. Furthermore, it is impossible to understand our foreign politics and involvement with Iraq. Supposedly we are making Iraq a democracy like ours, but can a Muslim theocracy be a democracy?
And about that unity Washington spoke of. It seems clear to me he was counting on religion to provide that unity. The general public wasn't educated to understand democrat principles and our unique relationship to our institutions until after 1840. You see there are two ways to have social control, culture or authority over the people. Our democratic republic, with liberty! was about relying on culture of social unity and control.
