Ethiopia — World Flags

The story behind the answer

Ethiopia is correct because its flag uses the original Pan‑African colors and uniquely includes a blue disc with a yellow star representing unity and equality among Ethiopia’s diverse peoples. Many African nations later adopted similar colors, but the central emblem sets Ethiopia’s apart.

Fun fact: Ethiopia is one of the world’s oldest states and the only African nation never fully colonized, which is why it became a symbol of African independence. Addis Ababa hosts the African Union. Memory tip: If you see the Pan‑African tricolor with a blue disc and star, think Ethiopia; no disc for Nigeria or Malawi, and Algeria has a crescent.
