This is very much a cold question as I have found no writings on any link. However, I do know that there was West African and European trade links long before colonialism and quite a bit of Mali gold found it's way to Europe. I also know the early Hungarian Kingdom did also control a substantial amount of gold mines in Europe but most of them had been quite depleted in antiquity.
I'm asking this based on legends, myself, of Magyar decent had heard passed down. It goes; As Magyar gold dwindled down in the second half of the middle ages the Kingdom began trading with the Mali empire at it's height providing cash crops like Hemp (still Hungary's largest cash crop) as well as textiles, paprika and lumber for Mali gold and some advanced iron worked products.
I don't know if there is any truth to this but it seems to specific and random for a story passed down through folk for it to not have something to it. If Anyone can answer or provide any information supporting or debunking the story I would be very appreciative. Thanks.
