The coasts of Tanzania, Kenya and Northern Mozambique have been ruled by foreign lands for centuries, from the Portuguese to the Omani Arabs. What if an Independent Empire emerged from the Swahili Coast, that would be able to resist colonization, That would expand into the Indian Ocean, conquering the Comoros and Northern Madagascar. I'm still undecided on the Capital, it could be Kilwa, Mombasa, Zanzibar, any large city. What do you think? Can it work?
