The physics of core-collapse supernovae (SNe) and how these explosions depend on the progenitor properties is a central question in our understanding the endpoints of stellar evolution. For only a handful of SNe, the progenitor star has been identified in pre-explosion images, however supernova remnants (SNRs), which are observed long after the original SN event, provide a unique opportunity to increase the number of progenitor measurements. In this talk, I will present our detailed study of the stellar populations found within the vicinity of supernova remnants found within the local group, with a focus on the SNRs in the Magellanic Clouds. Combined with constraints on the SNR metal abundances and environment from X-ray and optical observations, I will present our results in which we type the possible explosion mechanism and progenitor mass that resulted in the observed remnants. I will then discuss these results in the context of our understanding of the progenitors of SNe in nearby galaxies.
