Hurwitz numbers enumerate smooth covers of the projective plane with a given set of ramification conditions. Classically, this set of conditions required all ramification to be of order 1. There are many beautiful and deep results related to classical Hurwitz numbers. This includes the ELSV formula, a link to Gromov-Witten theory, links to mathematical physics and links to topological recursion.
