In this article are discussed the results of several studies of supern
ova remnants (SNRs) in the Magellanic Clouds. We study the relations o
f SNRs and their environment based on observations of both nebulae and
stars. We show the entire radial velocity field of the Small Magellan
ic Cloud. We present a new method of identification of SNRs based on t
heir kinematics that can be useful for identification of shocked nebul
ae in external galaxies. We discuss how a global knowledge of the prop
erties of SNRs in the Small Magellanic Cloud allows us to infer the ph
ase of evolution of these objects.
