The causes of wars are varied, usually related to territory, economic interests, natural resources, politics, and religion. Wars are also sometimes triggered by unexpected and unusual events. In the 20th century, the most famous is probably the so-called football war between El Salvador and Honduras in 1969. Less well-known is the conflict between Bulgaria and Greece in 1925, which was sparked by a runaway dog.
