The newest flag in the world belongs to Mauritania, which adopted a revised flag featuring two red stripes in 2017.
Mauritania, located in Africa, updated its national flag on August 15, 2017, adding two red stripes to symbolize the country's efforts and sacrifices for its homeland. The original flag featured a green field with a gold crescent and star, representing Islam, the major religion. The red stripes, one at the top and one at the bottom, were added to commemorate the sacrifices made by the Mauritanian people in their struggle for independence and nation-building.
While Denmark's flag is one of the oldest still in use, dating back to 1625, Mauritania's is the most recent official alteration to a national flag. Other countries may have had flag changes over time, but the 2017 revision of Mauritania's flag holds the title of the newest in the world.
