The facts which underlie these versions of the same historical events are wrapped in not a little doubt; and what is actually known is of the kind that may be read in a different sense by different eyes. CHAPTER XX. STORY OF A GRAND DUKE. When Alexander the First--elder brother of Constantine and Nicolas--died, unexpectedly, at Taganrog, on the distant Sea of Azof, leaving no son to reign in his stead, the crown descended, by law and usage, to the brother next in birth. Constantine was then at Warsaw, with his Polish wife; Nicolas was at St. Petersburg, with his guards. Constantine was called the heir; and up to that hour no one seems to have doubted that he would wear the crown, in case the Emperor's life should fail. There was, however, a party in the Senate and the barrack against him; the old Russian party, who could not pardon him his Polish wife. When couriers brought the news from Taganrog to St. Petersburg, Nicolas, having formed no plans as yet, called up the guards, announced his brother's advent to the throne, and set them an example of loyalty by taking the oath of allegiance to his Imperial Majesty Constantine the First. The guards being sworn, the generals and staff-officers signed the act of accession and took the oaths. Cantering off to their several barracks, these officers put the various regiments of St. Petersburg under fealty to Constantine the First; and Nicolas sent news that night to Warsaw that the new Emperor had begun to reign. But while the messengers were tearing through the winter snows, some members of the Senate came to Nicolas with yet more startling news. Alexander, they said, had left with them a sealed paper, contents unknown, which they were not to open until they heard that he was dead. On opening this packet, they found in it two papers; one a letter from the Grand Duke Constantine, written in 1822, renouncing his rights in the crown; the second, a manifesto by the dead Emperor, written in 1823, accepting that renunciation and adopting his brother Nicolas as his lawful heir. A similar packet, they alleged, had been secretly left with Philaret of Moscow, and would be found in the sacristy of his cathedral church. Nicolas scanned these documents closely; saw good reason to put them by; and urged the whole body of the Senate to swear fidelity to Constantine the First. In every office of the State the imperial functionaries took this oath. All Russia, in fact all Europe, saw that Constantine had opened his reign in peace.
