During European imperialism overseas, the
lines of amity were drawn to differentiate Europe from the rest of the world. The Line of Demarcation was one specific line drawn along a meridian in the
Atlantic Ocean as part of the
Treaty of Tordesillas in 1494 to divide new lands claimed by
Portugal from those of
Spain. This line was drawn in 1493 after
Christopher Columbus returned from his
maiden voyage to the
Americas.
The
Blue Line is a border demarcation between
Lebanon and
Israel published by the
United Nations on 7 June 2001 for the purposes of determining whether Israel had fully withdrawn from Lebanon.
The
Green Line (Lebanon) refers a line of demarcation in
Beirut,
Lebanon during the
Lebanese Civil War from 1975 to 1990. It separated the mainly Muslim factions in West Beirut from the predominantly Christian East Beirut controlled by the Lebanese Front.
The
Line of Contact was a demarcation line between Soviet-aligned forces and forces aligned with the Western allies, marking where Soviet-aligned forces and Western-aligned forces met as they advanced into Germany and Austria at the end of World War II in Europe.
