This paper is a report on recent progress made in the theory of Shimura varieties. The central problem is the expression of the Hasse-Weil zeta function of a Shimura variety in terms of automorphic L-functions. The author formulates this in terms of a trace formula. The crux of proving a formula of the expected form has recently been overcome by R. Kottwitz and the author is optimistic that positive, arithmetically useful results will soon be available.
