Rhetoric, inspirational and manipulative

I got to thinking about the article on "voter psychology" in the link I posted yesterday, and how memorable political speeches have succeeded in influencing (and swaying) the target audience.

I can think of one famous speech that is inspirational: the American civil rights activist Dr Martin Luther King Jr's "I Have A Dream" speech in 1963. It relies heavily on the use of rhetoric. Here is one link:

Another famous speech -- but fictional -- is the "Friends, Romans, Countrymen" speech by Mark Anthony in William Shakespeare's play Julius Caesar. In this case, while the speech also relies heavily on rhetoric, it is manipulative and designed to rouse a rabble crowd into hunting out the conspirators who had just stabbed Caesar to death. Here is one link and an assessment by Wikipedia:
