This was a talk I gave at the 2021 STFC Introductory Astronomy Summer School, which was hosted by The University of Hull. The talk gives a broad overview of stellar evolution, using the Hertzsprung-Russell diagram as the template to explain the key stages like protostar, main sequence, red giant, planetary nebular and the stellar remnants white dwarf stars, neutron star stars and black holes.
