Why is Peterson's algorithm better at mutual exclusion that its predecessors?

In very basic terms, what is the problem of mutual exclusion and how does Peterson’s Algorithm work? I only know that it sets variables equal to 0 or 1 as a way to signal which process can enter the critical region. What is the critical region? Why does Peterson’s Algorithm work better than the earlier attempts at mutual exclusion?
