The flag with blue, white, and green horizontal bands, a white crescent, and 12 white stars is the flag of Uzbekistan.
Uzbekistan’s national flag uses celestial blue, white, and green stripes separated by narrow red lines. A white crescent and 12 white five-pointed stars appear in the upper blue section near the hoist. The crescent is commonly associated with the nation’s historical and cultural traditions, while the stars have been linked to ideas including the ancient Uzbek calendar and spiritual completeness.
The flag was adopted on November 18, 1991, shortly after Uzbekistan became independent following the dissolution of the Soviet Union. It replaced the flag of the Uzbek Soviet Socialist Republic and established a visual identity distinct from the Soviet period.
The red lines are an important detail: they separate the main color bands and represent vital forces connecting the ideas symbolized by blue, white, and green. Kazakhstan and Turkmenistan also use blue and green in their flags, but neither has Uzbekistan’s exact combination of crescent and 12 stars.
