The betrothal ceremony was grandly celebrated. On the evening before, the Duke's private orchestra serenaded the Empress beneath the windows of the Winter Palace. The following day, after a service at Trinity Church and a dinner with the imperial family, the Duke was betrothed to Anne when Peter himself took rings from each prospective partner and exchanged them. The Emperor shouted "Vivat!" and the betrothal party moved on to a supper, a ball and a display of fireworks. At the ball, Peter, feeling ill, refused to dance, but Catherine, entreated by young Charles Frederick, danced a polonaise with him.
Anne lived only four years after her marriage and died when she was twenty. But fate used her and her husband to continue Peter's line on the Russian throne. They returned to Holstein, where at Kiel, shortly before her death, Anne gave birth to a son whose name became Karl Ulrich Peter. In 1741, when this boy was thirteen, his Aunt Elizabeth became empress. Unmarried and needing to designate an heir, she brought her nephew back to Russia and changed his name to Peter Fedorovich. In 1762, on Elizabeth's death, he succeeded to the throne as Emperor Peter III. Six months later, he was deposed and murdered by supporters of his German wife. This vigorous lady then seized the throne, was crowned Empress Catherine II and became known to the world as Catherine the Great. The son, grandsons and further descendants of Peter III and Catherine the Great occupied the Russian throne until 1917, all of them ultimately tracing their ancestry back through Princess Anne and Charles Frederick of Holstein, nephew of Charles XII, to Peter the Great.
Peter's efforts to marry both his daughters to foreign princes suggested that he did not envision either of them as his successor on the Russian throne. Indeed, no woman had ever sat on that throne. But the death of Peter Petrovich in 1719 left only one remaining male in the House of Romanov—Peter Alexeevich, son of the Tsarevich Alexis. Many Russians regarded him now as the legitimate heir, and Peter was well aware that the traditionalists looked upon the young Grand Duke as their future hope. This hope he was determined to thwart.
But if not Peter Alexeevich, who was to succeed? More and more, as he pondered the problem, the emperor's thoughts turned to the person closest to him: Catherine. Over the years, the passion which had first attracted Peter to this simple, robust young woman had ripened into love, trust and mutual contentment. Catherine was a partner of enormous energy and remarkable adaptability; although she loved luxury, she was equally good-humored in primitive circumstances. She traveled with Peter devotedly even when pregnant, and he often told her that her stamina was greater than his. They had bonds of joy in their daughters and shared grief over the numerous infants they had lost. They took pleasure in each other's company and were melancholy when apart. "Praise God, all is merry here," wrote Peter from Revan in 1719, "but when I come to a country house and you are not there, I feel so sad." Again, he wrote, "But when you state that it's miserable walking alone, although the garden is pleasant, I believe you, for it's the same for me; only pray God that this is the last summer we'll spend apart, and that we may always be together in the future."
It was during one of Peter's lengthy wartime absences that Catherine had prepared a surprise which had particularly delighted her husband. Knowing how much pleasure he took in new buildings, she secretly constructed a country palace about fifteen miles southwest of St. Petersburg. The mansion, built of stone, two stories high, and surrounded by gardens and orchards, was situated on a hill which looked back over the immense, flat plain stretching to the Neva and the city. When Peter returned, Catherine mentioned to him that she had found a charming deserted spot "where Your Majesty would not dislike to build a country house, if you would but take the trouble to go and see it." Peter immediately promised to go and "if the place really answers your description," to build any house she wished. The following morning, a large party set out, accompanied by a wagon carrying a tent under which Peter suggested they might eat. At the foot of the hill, the road began to climb and suddenly, at the end of an avenue of linden trees, Peter saw the house. He was still astonished when he arrived at the door and Catherine said to him, "This is the country house I have built for my sovereign." Peter was overjoyed and embraced her tenderly, saying, "I see that you wish to show me that there are beautiful places around Petersburg even though they are not on the water." She led him through the house, finally bringing him into a large dining room where a handsome table had been laid. He toasted her taste in architecture, and then Catherine raised her glass to toast the master of the new house. To his further astonishment and delight, the minute the glass touched Catherine's lips, eleven cannon hidden in the garden thundered a salute. When night fell, Peter said that he could never remember a day as happy as this one. In time, the estate came to be known as Tsarskoe Selo, the Tsar's Village, and Empress Elizabeth commanded Rastrelli to begin a gigantic new palace on the site. The magnificent Catherine Palace, which still stands, was named after her mother, the Empress Catherine I.
Peter's respect and gratitude to Catherine had been deepened by her participation in the military campaigns on the Pruth and in Persia. He had acknowledged these feelings publicly by their remarriage and by establishing the Order of St. Catherine in her honor. She already carried the courtesy title of empress as the wife of the Emperor, but now, as he faced the future without a son, he decided to go further. His first step, taken in February 1722 before he and Catherine departed for the Caucasus, was to issue a general decree concerning the succession. It declared that the ancient, time-honored rule by which the throne of the grand dukes of Muscovy and later the Russian tsars had been handed down from " father to son, or occasionally from elder brother to younger brother, was no longer valid. Henceforth, Peter decreed, every reigning sovereign would have absolute power to designate his or her successor. "Thus," he concluded, "children or children's children will not be tempted to fall into the sin of Absalom." The new decree also required all officials and subjects to swear an oath to accept the Emperor's choice.
Revolutionary though it was, the February 1722 ukase was only a preliminary step to a still more sensational act: Peter's declaration that he had decided to formally crown Catherine as empress. A decree of November 15, 1723, declared that whereas
our best beloved Spouse, Consort, and Empress Catherine has been a great support to us, and not only in this, but also in many military operations, putting aside womanly weakness, of her own will she has been present with us and has helped in every way possible ... for these labors of our Spouse we have decided that by virtue of the supreme power given us by God, she shall be crowned, which, God willing, is to take place formally in Moscow in the present winter.
Peter was treading on dangerous ground. Catherine was a Lithuanian servant girl who had come to Russia as a captive. Was she now to wear the imperial crown and sit on the throne of the Russian tsars? Although the manifesto proclaiming the coronation did not specifically name Catherine as heir, on the night before the coronation Peter told several senators and a number of important church dignitaries at the house of an English merchant that Catherine was being crowned in order to give her the right to rule the state. He waited for objections; he heard none.
