In Yorubá territory, in Africa, Ogum is the god of iron, of blacksmiths, and of all those who use this metal like agriculturers, hunters, buchers, etc. In Brasil Ogum is principally known as the god of the warriors. He lost his role as protector of agriculture as the last centuries slaves weren't interested in an abondant and good harvest, and thus didn't seek his protection in the matter.

In Brasil, followers of Ogum wear necklaces with darkblue and sometimes green glass beads. His day is tuesday. His name is always mentioned at the occasion of offerings that one makes to different Orixás, at the moment the head of an animal is cut off with a knife - of which he is the lord - and the blood begins to flow. He is also the first to be greeted, after having departed properly from Exu. When the manifested Orixás enter in thei traditional clothing, Ogum always walks in front, ''to open the way'' for the other Orixás.
