[Star Wars] Doesn't the Republic (now Empire) know that Palpatine and Darth Vader are Sith?

Why would the Republic (now Empire) follow Sith Lords, the enemy they've been fighting for years?

How would they know they're Sith? And how would they even know *what* a Sith is? 

Palpatine was the Chancellor who ended the Clone Wars, and he survived an assassination attempt by the Jedi Council - they wanted to take over. He's the best thing to happen to the galaxy.
