There were thenceforth several reasons why he should remain in or near Paris. His attentions to his young wife, and his desire to increase the splendour of the Court, counted for much. Yet more important was it to curb the clericals (now incensed at the imprisonment of the Pope), and sharply to watch the intrigues of the royalists and other malcontents. Public opinion, also, still needed to be educated; the constant drain of men for the wars and the increase in the price of necessaries led to grumblings in the Press, which claimed the presence of his Argus eye and the adoption of a very stringent censorship.[225] But, above all, there was the commercial war with England. This could be directed best from Paris, where he could speedily hear of British endeavours to force goods into Germany, Holland, or Italy, and of any change in our maritime code. Important as was the war in Spain, it was only one phase of his world-wide struggle with the mistress of the seas; and he judged that if she bled to death under his Continental System, the Peninsular War must subside into a guerilla strife, Spain thereafter figuring merely as a greater Vendée. Accordingly, the year 1810 sees the climax of his great commercial experiment. The first land to be sacrificed to this venture was Holland. For many months the Emperor had been discontented with his brother Louis, who had taken into his head the strange notion that he reigned there by divine right. As Napoleon pathetically said at St. Helena, when reviewing the conduct of his brothers, "If I made one a king, he imagined that he was _King by the grace of God_. He was no longer my lieutenant: he was one enemy more for me to watch." A singular fate for this king-maker, that he should be forgotten and the holy oil alone remembered! Yet Louis probably used that mediæval notion as a shield against his brother's dictation. The tough Bonaparte nature brooked not the idea of mere lieutenancy. He declined to obey orders from the brother whom he secretly detested. He flatly refused to be transferred from the Hague to Madrid, or to put in force the burdensome decrees of the Continental System.
