  With the advance of particle accelerator and detector technologies, the
neutrino physics landscape is rapidly expanding. As neutrino oscillation
experiments enter the intensity and precision frontiers, neutrino-nucleus
interaction measurements are providing crucial input. MINERvA is an experiment
at Fermilab dedicated to the study of neutrino-nucleus interactions in the
regime of incident neutrino energies from one to few GeV. The experiment
recorded neutrino and antineutrino scattering data with the NuMI beamline from
2009 to 2019 using the Low-Energy and Medium-Energy beams that peak at 3 GeV
and 6 GeV, respectively. This article reviews the broad spectrum of interesting
nuclear and particle physics that MINERvA investigations have illuminated. The
newfound, detailed knowledge of neutrino interactions with nuclear targets
thereby obtained is proving essential to continued progress in the neutrino
physics sector.
