The flag of Uzbekistan was approved at the Seventh Extraordinary Session of the Supreme Council of the Republic of Uzbekistan, on November 18, 1991.
The color blue represents the Turkic background of Uzbek people, white symbolizes holy peace, green symbolizes nature or Islam, and the red stripes symbolize the power of life. Note that sky blue or turquoise is a unique colour of Turks coming from ancient Tengrism religion.
The depiction of the crescent is connected to historical and religious traditions of Uzbekistan. The 12 stars are representative of spiritual and divine symbols. The significance of the number 12 (the number of months in an astronomical calendar) is the development of Islamic astronomy and scientific thought in Uzbekistan. There were also 12 principles that were used to lay the foundation of the Uzbek state.
