The National emblem of Angola reflects the recent past of the new nation. There is heavy Marxist imagery found on the device (as can be seen when compared with other examples of socialist heraldry), expanded from what is found on the national flag. In the center is a machete and hoe, representing the revolution through which the nation gained independence and the importance of agricultural workers. Above both emblems is a star, a common symbol in socialist emblems. The star is taken to represent progress. The rising sun is the traditional symbol of a new beginning. These emblems are all enclosed within a circle whose right half is formed by cog-wheel, representing the industrial workers, and whose left half is a half-wreath of maize, coffea and cotton leaves, representing agriculture. At the bottom is an open book that represents education. (Source: Wikipedia.org, CC BY-SA)
