On June 2, 1992, the self-proclaimed Republic of Nagorno-Karabakh, a de factoindependentrepublic in South Caucasus claimed by Azerbaijan, adopted a flag derived from the flag of Armenia, with only a white pattern added. A white, five-toothed, stepped carpet pattern was added to the flag, beginning at the two verges of the cloth's right side and connecting at a point equal to one-third of the distance from that side. The white pattern symbolizes the current separation of Artsakh (Nagorno-Karabakh) from Armenia proper and its aspiration for eventual union with "the Motherland." This symbolises the Armenian heritage, culture and population of the area and represents Nagorno-Karabakh as being a separated region of Armenia by the triangular shape and the zigzag cutting through the flag. The pattern is also similar to the designs used on rugs. The ratio of the flag's breadth to its length is 1:2, same as the Armenian Tricolor.
