Remilitarization refers to the process of re-establishing military forces or capabilities in a previously demilitarized area. This term is particularly significant in the context of European responses to fascism, as it highlights how certain nations began to ignore or violate post-World War I treaties, particularly the Treaty of Versailles, which aimed to limit military expansions. Remilitarization is a key indicator of rising tensions and the potential for conflict as nations sought to assert their power in the face of growing fascist movements.
