The Grand Embassy (1697–98)
Having already sent some young nobles abroad to study nautical matters, Peter, in 1697, went with the so-called Grand Embassy to western Europe. The embassy comprised about 250 people, with the “grand ambassadors” Franz Lefort, F.A. Golovin, and P.B. Voznitsyn at its head. Its chief purposes were to examine the international situation and to strengthen the anti-Turkish coalition, but it was also intended to gather information on the economic and cultural life of Europe. Travelling incognito under the name of Sgt. Pyotr Mikhaylov, Peter familiarized himself with conditions in the advanced countries of the West. For four months he studied shipbuilding, working as a ship's carpenter in the yard of the Dutch East India Company at Saardam; after that he went to Great Britain, where he continued his study of shipbuilding, working in the Royal Navy's dockyard at Deptford, and he also visited factories, arsenals, schools, and museums and even attended a session of Parliament. Meanwhile, the services of foreign experts were engaged for work in Russia.
On the diplomatic side of the Grand Embassy, Peter conducted negotiations with the Dutch and British governments for alliances against Turkey; but the Maritime Powers did not wish to involve themselves with him because they were preoccupied with the problems that were soon to come to a crisis, for them, in the War of the Spanish Succession.
The destruction of the streltsy (1698)
From England, Peter went on to Austria; but while he was negotiating in Vienna for a continuance of the anti-Turkish alliance, he received news of a fresh revolt of the streltsy in Moscow. In the summer of 1698 he was back in Moscow, where he suppressed the revolt. Hundreds of the streltsy were executed, the rest of the rebels were exiled to distant towns, and the corps of the streltsy was disbanded.
The Northern War (Northern War, Second) (1700–21)
When it became clear that Austria, no less than the Maritime Powers, was preparing to fight for the Spanish Succession and to make peace with Turkey, Peter saw that Russia could not contemplate a war without allies against the Turks, and he abandoned his plans for pushing forward from the Sea of Azov to the Black Sea. By the Russo-Turkish Peace of Constantinople (Istanbul, 1700) he retained possession of Azov. He was now turning his attention to the Baltic instead, following the tradition of his predecessors.
The Swedes occupied Karelia, Ingria, Estonia, and Livonia and blocked Russia's way to the Baltic coast. To dislodge them, Peter took an active part in forming the great alliance, comprising Russia, Saxony, and Denmark–Norway, which started the Northern War in 1700. This war lasted for 21 years and was Peter's main military enterprise. In planning it and in sustaining it he displayed iron willpower, extraordinary energy, and outstanding gifts of statesmanship, generalship, and diplomacy. Mobilizing all the resources of Russia for the triumph of his cause, constantly keeping himself abreast of events, and actively concerning himself with all important undertakings, often at his personal risk, he could be seen sometimes in a sailor's jacket on a warship, sometimes in an officer's uniform on the battlefield, and sometimes in a labourer's apron and gloves with an axe in a shipyard.
The defeat of the Russians at Narva (1700), very early in the war, did not deter Peter and, in fact, he later described it as a blessing: “Necessity drove away sloth and forced me to work night and day.” He subsequently took part in the siege that led to the Russian capture of Narva (1704) and in the battles of Lesnaya (1708) and of Poltava (Poltava, Battle of) (1709). At Poltava, where Charles XII of Sweden suffered a catastrophic defeat, the plan of operations was Peter's own: it was his idea to transform the battlefield by works of his military engineers—the redoubts erected in the path of the Swedish troops to break their combat order, to split them into little groups, and to halt their onslaught. Peter also took part in the naval battle of Gangut (Hanko, or Hangö) in 1714, the first major Russian victory at sea.
The treaties concluded by Russia in the course of the war were made under Peter's personal direction. He also travelled abroad again for diplomatic reasons—e.g., to Pomerania in 1712 and to Denmark, northern Germany, Holland, and France in 1716–17.
In 1703, on the banks of the Neva River, where it flows into the Gulf of Finland, Peter began construction of the city of St. Petersburg (Saint Petersburg) and established it as the new capital of Russia in 1712. By the Treaty of Nystad (September 10 [August 30, O.S.], 1721) the eastern shores of the Baltic were at last ceded to Russia, Sweden was reduced to a secondary power, and the way was opened for Russian domination over Poland.
In celebration of his triumph, the Senate on November 2 (October 22, O.S.), 1721, changed Peter's title from tsar to that of emperor (imperator) of all the Russias.
The popular revolts (1705–08)
The peasant serfs and the poorer urban workers had to bear the greatest hardships in wartime and moreover were intensively exploited in the course of Peter's great work for the modernization and development of Russia (see below Internal reforms). Their sufferings, combined with onerous taxation, provoked a number of revolts, the most important of which were that of Astrakhan (1705–06) and that led by Kondraty Afanasyevich Bulavin in the Don Basin (1707–08). These revolts were cruelly put down.
The Turkish War (Russo-Turkish wars) (1710–13)
In the middle of the Northern War, when Peter might have pressed further the advantage won at Poltava, Turkey declared war on Russia. In the summer of 1711 Peter marched against the Turks through Bessarabia into Moldavia, but he was surrounded, with all his forces, on the Prut River. Obliged to sue for peace, he was fortunate to obtain very light terms from the inept Turkish negotiators, who allowed him to retire with no greater sacrifice than the retrocession of Azov. The Turkish government soon decided to renew hostilities; but the Peace of Adrianople (Edirne) was concluded in 1713, leaving Azov to the Turks. From that time on Peter's military effort was concentrated on winning his war against Sweden.
The Tsarevich Alexis and Catherine (to 1718)
Peter had a son, the tsarevich Alexis, by his discarded wife Eudoxia. Alexis was his natural heir, but he grew up antipathetic to Peter and receptive to reactionary influences working against Peter's reforms. Peter, meanwhile, had formed a lasting liaison with a low-born woman, the future empress Catherine I, who bore him other children and whom he married in 1712. Pressed finally to mend his ways or to become a monk in renunciation of his hereditary rights (1716), Alexis took refuge in the dominions of the Holy Roman emperor Charles VI, but he was induced to return to Russia in 1718. Thereupon proceedings were brought against him on charges of high treason, and after torture he was condemned to death. He died in prison, presumably by violence, before the formal execution of the sentence.
The Persian campaign (1722–23)
Even during the second half of the Northern War, Peter had sent exploratory missions to the East—to the Central Asian steppes in 1714, to the Caspian region in 1715, and to Khiva in 1717. The end of the war left him free to resume a more active policy on his southeastern frontier. In 1722, hearing that the Ottoman Turks would take advantage of Persia's weakness and invade the Caspian region, Peter himself invaded Persian territory. In 1723 Persia ceded the western and southern shores of the Caspian to Russia in return for military aid.
