Watching historical stuff on youtube (I download and watch during my commute), today I learned how the Portuguese managed to get a very firm hold on the western coast of India in the early 1500s. The TLDR version is that they managed to get the cities that were vassals of Calicut under their wing, and even managed to fight off a massive siege the raja of Calicut sent to destroy their small garrison at Kochin in 1504: a 50k strong force was beaten by a garrison of 90 Portuguese soldiers + ~200 local Nayar warriors + 3 Portuguese ships (1 carrack and 2 caravels).
Before it got to that part, I also learned that Vasco da Gama, who led the initial demands on Calicut, was a short tempered psycopath and violent maniac hell bent on teaching “those muslims” a lesson.
