Well racially speaking Persians are partially indo European, the steppe people whom conquered them formed a ruling class and didnt have a very great impact genetically.
Arent Persians, Greeks, Scythians and Italians indo european speaking? if you dont know go google it.
They picked up their language thousands of years ago from a wild steppe people whom invaded then subjugated and mixed with much of South Asia and Europe.
I thought Persians were like Arabs. you learn a new thing everyday wlh
did these people control all of Somalis or did the just control Muqdisho and other port cities?
you are right that Arab influence strengthened Somali and created the Ajuuran empire.
From what i know Indo Europeans didnt step a foot into Africa let alone Somalia. If your referring to early middle ages when Arabs and Persians colonized and built mogadishu, then in that case yes. The Arabs had a huge impact on Somalis, both north and south. They built the local towns (zeila, Mogadishu) which allowed us to trade and urbanise, influenced our language and culture, imported technology and tools which allowed us to farm and build .
