Total defence is a defence policy combining and extending the concept of military defence and civil defence. It entails a high level of readiness of both the state and its society to defend itself in cases of dangers and catastrophes such as war, crisis, or natural disasters. Total defence represents all activities preparing the society for war. It implies that in a state of war or emergency, all functions of society, both military and civilian, are included in the defence efforts. This means that in the event of a crisis, all social institutions, such as army, police, parliament, government and its agencies, local authorities, the health system, civil society organizations, entrepreneurs, and individuals would all be mobilized to defend the state.
