The flag of Angola consists of two horizontal bands of red and black with a yellow emblem in the center. The red half is on the top and the black half is on the bottom. The emblem consists of a five-pointed star within a half gear wheel crossed by a machete (similar in appearance to a hoe, a tool used in agriculture).

Here is the symbolism associated with the colors and the emblem:

1. Red: Represents the blood shed by Angolans during their independence struggle, the anti-colonial struggle, and the defense of the country.

2. Black: Symbolizes the African continent.

3. Yellow Emblem:

   • Half Gear Wheel: Represents the workers and industrial production.
   • Machete: Symbolizes the peasants, agricultural production, and the armed struggle.
   • Five-pointed Star: Symbolizes international solidarity and progress. The star is often associated with Marxism and is believed to represent the ruling party’s (MPLA) socialist orientation.

The flag was adopted on November 11, 1975, when Angola gained independence from Portugal. The design is heavily influenced by the flag of the MPLA (Popular Movement for the Liberation of Angola), which was a major political and armed organization in the fight for independence.

The use of red and black in the flag also reflects influence from the flag of the African Party for the Independence of Guinea and Cape Verde (PAIGC), another anti-colonial movement in the region that had close ties with the MPLA.

Overall, the flag reflects Angola's history of struggle, its socialist orientation during the early years of independence, and its African identity.
