I started looking for a thread that had was about and had many documentaries in it and I couldn't find one. So I'll try to make one here, feel free to link any good documentaries about trading, piracy, naval nations etc, and I'll try to keep it updated. I myself find it very interesting to expand my knowledge about this time period and to have a collection of documentaries easily accessible. If the mass enjoys this feel free to sticky it. Enjoy, Antihide.
