[Star Wars] I understand that the rebels are battling the Empire, but why? What was the issue with the Empire running the universe? High taxes, too conservative, too authoritarian?

Maybe it’s explained in one of the movies, but I must have missed it. It’s clear they are pretty brutal and authoritarian, but so are most countries when dealing with violent rebels.

Well, there are a few little things. Just minor quibbles, you know.

The dismantling of all forms of democratic representation. The government being under the control of a ruthless dictator-for-life. The use of tactics like orbital bombardment on civilian populations. The strip-mining of worlds down to the mantle to fuel the galactic war machine. The reduction of non-human populations to second-class citizens on their own homeworlds. The mass use of slavery. The Lasan massacre. The Geonosian genocide. The replacement of traditional bureaucracy with the constant threat of planetary annihilation. 

They aren't just brutal to the rebels, they're brutal to everyone.
