As soon as the French tricolor was raised above the consulate at Warsaw, the trouble commenced. Taken unprepared, Constantine withdrew with his troops. Again the Poles were divided; the patriots advised reconciliation with Russia, while hotheads demanded the abdication of the Romanofs. The first party sent a deputation to St. Petersburg and another to Paris and London, to secure mediation. The czar's answer was decisive; he absolutely refused to "make concessions (to the revolutionists), as the price of their crimes." Again, too, there was discord among the leaders as they entered upon a life or death struggle. Poland appealed to Europe. The people were sympathetic, but the governments, rejoicing at seeing a revolutionary movement suppressed, refused to interfere. In February, 1831, a Russian army of 130,000 men invaded Poland. (p. 211) The Poles showed a heroism which appealed to the people of Europe, but more than sympathy was needed to arrest the irresistible Russian advance upon Warsaw. Constantine and the Russian commander-in-chief fell the victims of cholera, but an epidemic of discord struck Poland and sealed its fate. On the 6th of September, Warsaw was invested. The capital was forced to surrender. "Warsaw is at your feet," wrote the commander-in-chief to the czar, who lost no time in trampling upon the conquered. The constitution was abrogated, the Diet, a thing of the past. Poland was no more. Where it had stood, was a Russian province. Russian officials introduced Russian taxes, Russian coinage, and Russian justice such as it was. The Poles saw samples of it when thousands were arrested without process of law, and were sent to prison or to Siberia, while other thousands lost their property by confiscation. In White Russia and Lithuania the use of the Polish language was prohibited and the Catholic Clergy were forced to "ask" admittance to the bosom of the Greek Church. It must be admitted that the Polish peasants benefited by the change. With a view of reducing the influence of the nobles, the government issued regulations protecting the laborer against the landowner. The Polish revolution caused the reorganization of European policies. Austria and Prussia, each in possession of territory that formerly belonged to Poland, entered into friendly relations with Russia, whereas England and France, where public opinion could not be ignored, drew more closely together. Nicholas was posing as the arbiter of (p. 212) Europe and the champion of kings. He assumed the right to command, but would soon find his will contested.
