Such events as Burr's conspiracy or the conquest of Texas cannot be properly understood if we fail to remember that they were but the most spectacular or most important manifestations of what occurred many times. The Texans won a striking victory and performed a feat of the utmost importance in our history; and, moreover, it happened that at the moment the accession of Texas was warmly favored by the party of the slave-holders. Burr had been Vice-President of the United States, and was a brilliant and able man, of imposing personality, whose intrigues in the West attracted an attention altogether disproportionate to their real weight. In consequence each event is often treated as if it were isolated and stood apart from the general current of western history; whereas in truth each was but the most striking or important among a host or others. The feats performed by Austin and Houston and the other founders of the Texan Republic were identical in kind with the feats merely attempted, or but partially performed, by the men who, like Morgan, Elijah Clark, and George Rogers Clark, at different times either sought to found colonies in the Spanish-speaking lands under Spanish authority, or else strove to conquer these lands outright by force of arms. Boone settled in Missouri when it was still under the Spanish Government, and himself accepted a Spanish commission. Whether Missouri had or had not been ceded first by Spain to France and then by France to the United States early in the present century, really would not have altered its final destiny, so far at least as concerns the fact that it would ultimately have been independent of both France and Spain, and would have been dominated by an English-speaking people; for when once the backwoodsmen, of whom Boone was the forerunner, became sufficiently numerous in the land they were certain to throw off the yoke of the foreigner; and the fact that they had voluntarily entered the land and put themselves under this yoke would have made no more difference to them than it afterwards made to the Texans. So it was with Aaron Burr. His conspiracy was merely one, and by no means the most dangerous, of the various conspiracies in which men like Wilkinson, Sebastian, and many of the members of the early Democratic societies in Kentucky, bore a part. It was rendered possible only by the temper of the people and by the peculiar circumstances which also rendered the earlier conspiracies possible; and it came to naught for the same reasons that they came to naught, and was even more hopeless, because it was undertaken later, when the conditions were less favorable.
