This map layer line presents the timeline of wars and conflicts for all available countries, classified in four categories for the years 1946 to 2017.
The underlying definition of war takes wars or conflicts into account in which at least one state is party to the conflict and in which more than 25 persons have been killed due to fighting. It also differentiates between four categories of war/violent conflict: extra-state/-systemic violent conflict (state against non-state actors outside of its own borders) inter-state (between two states), intra-state (state against non-state actor within its own borders) and internationalised intra-state conflicts (state aided by other states against non-state actor within its own borders).
