recs for books and documentaries on somalia?

i want to study my country-in depth. i feel like a dhaqancelis for having a simple understanding of my history? what was somalia like during the Prophet’s time? what was it like during the khulafa era, what was it like pre world wars? why is it so fragmented now etc (although i do have the understanding for the last question). i really want to educate myself and be on a journey of self-transformation
