Northern Opium War (Premysloides Dynasty)

Background
Since early time, Imperial Trade Company was active in various illicit activities, include illegal smuggling, kidnappings, extortions, raiding (aside of their "normal" economic and commercial activities). One of their dubious activity was opium production and trading.

After War of Polish Succession, Southern Poland became important part of opium production and each year, ITC produced about 15,000 tonns of opium in Poland and later (1460), production reached about 85,000 tonns. About tenth of production was consumed by imperial population, as imperial laws were very liberal toward some kinds of drugs, but 90% were exported to various countries. Some accepted it (Hindu Communion, Portugal), some banned it (England) and some decided for war (Scandinavia and African Commonwealth, which was ravaged by terrible problems with opium and opium caused many problems within African society and economy).

Imperial Trade Company also had own port towns, trading posts and various "rented" counties in newly formed Kalmar Union of Norway, Sweden and Finland. In Helsinki, ITC owned 5,000m2of lands and used it for their naval trade. Oslo was important station for opium trade, as it was Baltic and Northern Sea, used to transporting opium in to Portugal, Africa and Scandinavia.

In late 1465, King Christopher I of Kalmar Union, demanded Imperial emissars to stop ITC with selling opium on Kalmar markets. He proposed that ITC can continue in using Oslo ports, but any opium selling will be punished by death of both, seller and buyer.
