Algebraic Numbers

I've been trying to find out how to get Mathematica to work with algebraic
numbers. For example, I'd like to declare z to be a primitive m-th root of
unity (where m is usually some small number like 5 or 9), and then have it
correctly reduce polynomials in z. I tried

AlgebraicRules[z^4+z^3+z^2+z+1==0,{z}]

(for m=5, of course), and it didn't seem to be able to recognize z^5 as 1.
This must be doable! Can anyone out there tell me how?
