In Europe, hemp was widely used both industrially and medicinally, from the Black Sea (Crimean) to the British Isles, especially in Eastern Europe. The papal ban on cannabis medicines in the Holy Roman Empire in 1484 was quite unenforceable north of the Alps, and to this day the Romanians, Czechs, Hungarians, and Russians dominate the world cannabis agronomy.In Ireland, already world famous for its cannabis linen, the Irish woman who wanted to know whom she would eventually marry was advised to seek revelation through cannabis marijuana seeds.Eventually, the hemp trades once again became so important to the empire builders who followed (in the Age of Discover/Reason, the 14th to 18th Centuries) that they were central to the intrigues and maneuverings of all the World's great powers.
