The statement of the Riemann hypothesis makes sense for all global
fields, not just the rational numbers. For function fields, it has a
natural restatement in terms of the associated curve. Weil's work on
the Riemann hypothesis for curves over finite fields led him to state
his famous "Weil conjectures", which drove much of the progress in
algebraic and arithmetic geometry in the following decades. In this
article, I describe Weil's work and some of the ensuing progress.
