Seems like these Portuguese had been all through the african coast, i wonder why they didn't colonise south africa (given that they had angola and mozambique), they came to east africa in the 1400 to 1500s but were driven out by the waswahili bantus who had already assimilated into a muslim culture. We have a huge fortress known as Fort Jesus in Mombasa city Kenya which they built and where they barricaded themselves against the arabs and the waswahili, there are lots of war cannons too .
