Not least of Kentucky's trials was the political discontent among her own people, which for many years lay like a blight upon her happiness and prosperity. Virginia's home necessities had prevented that commonwealth from giving much aid to the West during the Revolution, and at its conclusion her policy toward the Indians lacked the aggressive vigor for which Kentuckians pleaded. This was sufficient cause for dissatisfaction; but to this was added another of still greater importance. To gain the free navigation of the Mississippi, and thus to have an outlet to the sea, long appeared to be essential to Western progress. At first the Eastern men in Congress failed to realize this need, thereby greatly exasperating the over-mountain men. All manner of schemes were in the air, varying with men's temperaments and ambitions. Some, like Clark--who, by this time had, under the influence of intemperance, greatly fallen in popular esteem, although not without followers--favored a filibustering expedition against the Spanish; and later (1788), when this did not appear practicable, were willing to join hands with Spain herself in the development of the continental interior; and later still (1793-94), to help France oust Spain from Louisiana. Others wished Kentucky to be an independent State, free to conduct her own affairs and make such foreign alliances as were needful; but Virginia and Congress did not release her. Interwoven with this more or less secret agitation for separating the West from the East were the corrupt intrigues of Spain, which might have been more successful had she pursued a persistent policy. Her agents--among whom were some Western pioneers who later found difficulty in explaining their conduct--craftily fanned the embers of discontent, spread reports that Congress intended to sacrifice to Spain the navigation rights of the West, distributed bribes, and were even accused of advising Spain to arm the Southern Indians in order to increase popular uneasiness over existing conditions. Spain also offered large land grants to prominent American borderers who should lead colonies to settle beyond the Mississippi and become her subjects--a proposition which Clark once offered to accept, but did not; but of which we shall see that Daniel Boone, in his days of discontent, took advantage, as did also a few other Kentucky pioneers. Ultimately Congress resolved never to abandon its claim to the Mississippi (1787); and when the United States became strong, and the advantages of union were more clearly seen in the West, Kentucky became a member of the sisterhood of States (1792).
