Supernova remnants (SNRs) are the long lived structures that result from the explosive end of a massive star. The expanding shock-front produced by the supernova explosion heats stellar ejecta and swept-up ISM to X-ray emitting temperatures,  and are sites in which populations of relativistic particles can be efficiently accelerated to the knee of the Cosmic-ray spectrum. Until recently, most studies have focused on understanding the properties of individual SNRs. However, in this talk I will focus on the importance of systematic studies of these objects and the power that these type of studies gives us in regards to better understanding these objects. In particular, I will highlight current investigations into the high energy emission of SNRs using X-ray and gamma-ray satellites, which aim to give us an insight into the characteristics of its progenitor and explosion type, while also better understand the effect that the surrounding environment has on their properties and their ability to accelerate particles.
