History
Kyrgyz are a Turkic ethnic group found primarily in Kyrgyzstan.
There are several etymological theories on the name "Kyrgyz." First, the name Kyrgyz may mean "forty girls" (кырк + кыз), a reference to the Manas epic unifying forty small tribes against the Chinese on one side and the Muslim expansion on the other. This is symbolized by the yellow sun in the center of the flag of Kyrgyzstan, which has 40 rays referring to forty Kirghiz tribes. Next, a meaning of "forty tribes" (кырк + ууз) which makes more direct sense. Finally, a meaning with totally different word formulation (кыргыс, adj.), meaning "imperishable", "inextinguishable" or "undying". This version has an obvious popular appreciation. Historical evidence for many conflicts with other peoples also supports this theory.
