What was the "Spanish Conspiracy" and what did it represent?

Spanish Conspiracy", as it is known, was initiated by Wilkinson's "First Memorial", a 7,500-word report written before he left New Orleans for Charleston, to the Spanish concerning the "political future of western settlers" and to convince Spain to "admit us [Kentuckians] under protection as vassals".

The Spanish Conspiracy involved a plot to open the Mississippi River by a Kentuckian angry at the economic impact caused by Spain's closing of the waterway to American trade.
