The 19 pages that link to Minkowski spacetime, each with the reason it gives.
SpacetimeBroader topic: It provides the simplest spacetime geometry, without gravity or curvature.
Four-vectorNarrower topic: Its metric defines the invariant norm shared by all four-vectors.
Lorentz covarianceRelated: Its invariant geometry is what Lorentz transformations preserve.
Lorentz groupNarrower topic: The Lorentz group acts as a symmetry group of this spacetime.
Poincaré groupNarrower topic: The Poincaré group is precisely its group of isometries.
