Emblem of Mozambique

The national emblem of Mozambique was adopted in 1990 in the Constitution of Mozambique article 194. The article clearly states the design and meaning of the device. It shows a gear wheel, bordered by corn stalks and sugarcane. In the middle there is a red sun over a map of Mozambique in green, and blue waves, an AK-47 crossed with a hoe, and a book. The wreath is tied with a ribbon bearing the name of the country. The emblem is "socialist heraldry" style similar to those of the Soviet republics.
Description.
As described in the Mozambican constitution article 194, the various parts of the emblem have a special symbolism, i.e.
From 1975-1982, the map of Mozambique was brown instead of green. Along with this change of colour, the position of the wreath was changed, the text was changed from black to gold, and a gold border was added around the red star.
In 1990, with the implementation of the new constitution, the name of the country was changed from "República Popular de Moçambique" to "República de Moçambique", and the text on the emblem was changed accordingly.
Mozambique's parliamentary opposition would specifically like to see removed the image of the Kalashnikov assault rifle, which symbolizes the nation's struggle for independence, according to press reports.
Historical coats of arms.
In 1935, the Portuguese colonies were officially assigned coats of arms that followed a standard design pattern.
