"The seven years' war" between France and England, ended in the cession, to the latter power, of all the French possessions in North America, except Louisiana. It was stipulated, between the two crowns, that the boundary line of their respective dominions, in the New World, should run along the middle of the Mississippi, from its source as far as the Iberville, and along the middle of that river, and of Lakes Maurepas and Pontchartrain. This was in 1763. In the course of the same year, Louisiana was transferred by treaty to the crown of Spain. The tidings of this unexpected cession, which were not promulgated until two years after the execution of the treaty, spread dismay through the colony. The idea of being passed over, nolens volens, to the domination of Spaniards, was revolting to the thousands of true hearted and loyal Frenchmen, who had acquired and defended the territory, and claimed it as their own. They resolved, as one man, to resist this unceremonious change of masters, apparently determined, if their old mother, France, persisted in casting them off, to set up for themselves.
In pursuance of this resolution, they refused to receive Don Ulloa, whom the King of Spain despatched in 1766, to take possession of the Province, and to assume the Government, as his representative. The point was disputed at the cannon's mouth, but the colony prevailed, and Don Ulloa returned with his dishonored commission, to his master. Charles was as indignant as his crest-fallen servant, at this unexpected repulse. But he was too busy with his own troubles at home, to pursue the matter at that moment.
A fit instrument of Royal vengeance was at length found, in the person of Don O'Reilly, a renegade Irishman, who, in 1769, was appointed to subdue and rule over the refractory province. A more perfect exemplification of the remark, that the most depraved unprincipled man may gain the confidence and regard of Kings, can scarcely be found. In the execution of his trust, he showed himself a very fiend incarnate. First, by fair promises, cautiously mingled with just as much of intimidation, as would give an air of candor and courtly conciliation to his promises, he induced the too credulous Louisianians to abandon their purpose of resistance, and surrender without striking a blow. This artful guise he continued to wear, till he had obtained possession of all the insignia of government, and the sinews of power, and placed his own chosen tools in all the chief places of trust. Then the mask of hypocrisy was boldly thrown off, and the cloven foot uncovered. His fair promises were immediately shown to be only a master stroke of policy, to gain an end. In the face of his solemn stipulations, he caused those who had been foremost in refusing submission to his authority, to be seized and put to death. Five of them, principal citizens of New Orleans, he caused to be publicly shot. Five more he consigned to the dungeons of the Moro, at Havana, and one he procured to be assassinated. Other acts of cold-blooded cruelty, and false-hearted tyranny followed, till he became the execration and abhorrence of the whole colony. He introduced the Spanish colonial system, and subjected the inhabitants to every species of indignity and abuse. At length, the extravagance of his measures, and his unprincipled abuse of power, wrought its own ruin. He was recalled by his King, and disgraced—if one already so infamous could by any means be rendered more so. His successor was Unzoga, who was shortly after superseded by Galvez.
The colony now enjoyed a brief season of comparative quiet. But the war between England and Spain, which broke out in 1779, afforded an opportunity for Governor Galvez to show his loyal zeal, and exercise his military talents. With the troops under his command, he invaded Florida, took possession of Baton Rouge, and Fort Charlotte, near Mobile, and proceeded to Pensacola, which, after an obstinate resistance, also submitted to his authority. Thus was the Spanish dominion completely established in Florida.
Governor Miro, who succeeded Galvez, carried into full effect the colonial system of Spain, which was by no means relished by the French inhabitants of the colony.
In 1785, a new firebrand was thrown into the midst of these combustible elements. An attempt was made to establish an office of the Inquisition in Louisiana. It was fearlessly opposed, and fortunately crushed without bloodshed. The agent, to whom the obnoxious business was entrusted, was seized in his bed, conveyed forcibly on board a vessel, and sent home to Spain.
A census of the province, taken in 1788, just ninety years from the date of the first settlement, showed a population of 42,611. Of these, 19,445 were whites, 21,465 slaves, and 1701 colored freemen. New Orleans, then 70 years old, contained 5,338 inhabitants.
The Baron de Carondelet was appointed Governor in 1792. During his administration, in the year 1794, the first newspaper, called "Le Moniteur," was published in Louisiana. At the same period the Canal Carondelet was commenced; and the cultivation of indigo and the sugar cane, which had hitherto been the great staples of the colony, was suspended.
In 1795, by the treaty of St. Lorenzo, the navigation of the Mississippi was opened to the western States of the Union, and the great impulse given to the commercial prosperity of New Orleans, which secured forever the pre-eminence of the Crescent City. The same treaty defined the boundaries, as they now exist, between Florida and Mississippi. But Carondelet, being rather more tardy in yielding possession, than suited the active, enterprising spirit of the Americans, the territory was seized by an armed force, under Andrew Elliott.
Two years after this, a plan set on foot by Carondelet, to dismember the American Union, by drawing the Western States into a separate compact, was detected and defeated by the address of General Wilkinson. Whether Aaron Burr was in the plot, or only took a hint from it a few years later, does not appear of record. Carondelet was succeeded by Gayosa de Lamor, Casa Calvo, and Salvado, who, successively, but for a very brief period, wielded the chief magistracy of the colony.
