He was basically
responsible for Emperor Sideous Palpatine's rise to power because in Episode 2, he actually GAVE Palpatine the supreme power of waging war on any planet that dared to challenge the Republic.
Unfortunately, in Episode 3, we will then see Palpatine turning against and crushing the Republic with the help of evil Anakin Skywalker/
Darth Vader. And we can all thank Jar Jar Binks for that.
