King Aweida was a royal man in Nauru. Before Nauru became under white rule, they were governed by the king who made the laws which were enforced by their own chiefs. When Germany came on Nauru, take it over and then annexed the island to German New Guinea, he although could hold his sovereignty as king and kept to be the chieftain of the Nauruan people. Otherwise, it's not much known about him.

In the photograph, King Aweida is wearing the top hat. His wife, the queen, is wearing a white robe.

In the second photograph, he's standing (in the middle) before Germany's realm flag.
