The Hitchin system, discovered in 1987, is a moduli space arising from the geometric study of the Yang-Mills equations on Riemann surfaces. Over the past 30 years it has become both a unifying structure and an important tool for probing many questions at the interface of complex algebraic geometry, representation theory, and integrable systems. A strong case can be made for the claim that all roads lead to the Hitchin system, at least so far as these subjects are concerned. I intend to demonstrate this from several points of view, including that of hyperpolygons, whose Hitchin system-like properties were recently explored by J. Fisher and myself.
