In July 1807 Napoleon I of France and Csar Alexander I of Russia signed the Treaties of Tilsit in the town of Tilsit. This treaty ended war between Imperial Russia and the French Empire and began an alliance between the two empires that rendered the rest of continental Europe almost powerless.  The two countries secretly agreed to aid each other in disputes.  The treaty created an alliance between Russia, France, Prussia, Denmark, and others forcing them to break all ties, trade and commerce, with England in an attempt to isolate England from Russia.  Russia was one of the international main exporters, they dominated the international hemp trade and hemp was England’s most vital commodity with Russia supplying 90 percent. England was the top international importer of hemp. The flourishing Russian economy and stable hemp trade between England and  Russia was a very powerful imminent threat to Napoleons France.  Through the Treaties of Tilsit Napoleon tried to gain control of the international hemp trade and market. Although the treaty was signed by both parties,  the Czar could not enforce the treaty and Russia didn't keep his promise because most of their economy depended on the trade with Britain so the clandestine  trade with Britain continued to flourish.. they say money talks .. promises walk ..
