The bottom band on Yemen’s national flag is black.
Yemen’s flag is a horizontal tricolour arranged from top to bottom as red, white, and black. It became the national flag of the Republic of Yemen on May 22, 1990, the day North Yemen and South Yemen unified.
The design is derived from the Arab Liberation Flag, a pan-Arab symbol that influenced several flags in the region during the 20th century. Yemen’s official interpretations describe the red as representing unity and the blood of martyrs, the white as a bright future, and the black as the dark days of the past. The bands contain no emblem, star, text, or coat of arms.
Readers sometimes confuse the Yemeni flag with older North or South Yemeni flags, which included distinctive symbols such as stars or other devices. The modern national flag deliberately removed those regional elements after unification. It also resembles several other Arab tricolours, so the order of the bands is the key detail: red on top, white in the middle, and black at the bottom.
