Young Massive Clusters as probes of stellar evolution
  Young Massive Clusters (YMCs) represent ideal testbeds in which to study
massive stellar evolution as they contain large, coeval, chemically
homogeneous, samples of massive stars. By studying YMCs with a range of ages
(and hence turn-off masses), we can investigate the post main-sequence
evolution of massive stars as a function of initial mass. Recent discoveries of
YMCs over a range of ages within our own Galaxy - where we can successfully
resolve individual stars - offers the unprecedented opportunity to test our
ideas of massive stellar evolution. Here, I review some of the recent works in
this field, and describe how we can use YMCs to investigate several topics,
including (a) the evolutionary state of H-rich Wolf-Rayet stars; (b) the
influence of binarity on stellar evolution in dense clusters; and (c) Red
Supergiants and the post-supernova remnants they leave behind.
