Great Northern War

Peter made a temporary peace with the Ottoman Empire that allowed him to keep the captured fort of Azov, and turned his attention to Russian maritime supremacy. He sought to acquire control of the Baltic Sea, which had been taken by the Swedish Empire a half-century earlier. Peter declared war on Sweden, which was at the time led by the young King Charles XII. Sweden was also opposed by Denmark–Norway, Saxony, and the Polish–Lithuanian Commonwealth. The Preobrazhensky regiment took part in all major battles of the Great Northern War.

Russia was ill-prepared to fight the Swedes, and their first attempt at seizing the Baltic coast ended in disaster at the Battle of Narva in 1700. In the conflict, the forces of Charles XII, rather than employ a slow methodical siege, attacked immediately using a blinding snowstorm to their advantage. After the battle, Charles XII decided to concentrate his forces against the Polish–Lithuanian Commonwealth, which gave Peter time to reorganize the Russian army and conquered Nyenschantz in the Ingrian campaign. Bidloo had to organize a military hospital. Robert Bruce was appointed commander-in-chief of St. Petersburg. After the defeat at Narva, Peter I gave the order to melt the church bells into cannons and mortars. In 1701 Peter ordered the construction of Novodvinsk Fortress north of Archangelsk. Everybody was convinced they knew: his Majesty will wage war. In the siege of Nöteborg Russian forces captured the Swedish fortress, renamed Shlisselburg. In 1702 Peter the Great established the Olonets Shipyard at Lodeynoye Pole, where Russian frigate Shtandart was built.

While the Poles fought the Swedes, Peter founded the city of Saint Petersburg on 29 June 1703 on Hare Island. He forbade the building of stone edifices outside Saint Petersburg, which he intended to become Russia's capital, so that all stonemasons could participate in the construction of the new city. While the city was being built along the Neva he lived in a modest three-room log cabin (with a study but without a fire-place) which had to make room for the first version of the Winter Palace. The first buildings which appeared were a shipyard at the Admiralty, Kronstadt (1704-1706) and the Peter and Paul Fortress (1706). Peter took his whole family on a boat trip to Kronstadt.

Following several defeats, Polish King Augustus II the Strong abdicated in 1706. Swedish king Charles XII turned his attention to Russia, invading it in 1708. After crossing into Russia, Charles defeated Peter at Golovchin in July. In the Battle of Lesnaya, Charles suffered his first loss after Peter crushed a group of Swedish reinforcements marching from Riga. Deprived of this aid, Charles was forced to abandon his proposed march on Moscow.

Charles XII refused to retreat to Poland or back to Sweden and instead invaded Ukraine. Peter withdrew his army southward, employing scorched earth, destroying along the way anything that could assist the Swedes. Deprived of local supplies, the Swedish army was forced to halt its advance in the winter of 1708–1709. In the summer of 1709, they resumed their efforts to capture Russian-ruled Ukraine, culminating in the Battle of Poltava on 27 June. The battle was a decisive defeat for the Swedish forces, ending Charles' campaign in Ukraine and forcing him south to seek refuge in the Ottoman Empire. Russia had defeated what was considered to be one of the world's best militaries, and the victory overturned the view that Russia was militarily incompetent. In Poland, Augustus II was restored as King.

Peter, overestimating the support he would receive from his Balkan allies, attacked the Ottoman Empire, initiating the Russo-Turkish War of 1710. Peter's campaign in the Ottoman Empire was disastrous, and in the ensuing Treaty of the Pruth, Peter was forced to return the Black Sea ports he had seized in 1697. In return, the Sultan expelled Charles XII. The Ottomans called him Mad Peter (Turkish: deli Petro), for his willingness to sacrifice large numbers of his troops in wartime.

Peter's northern armies took the Swedish province of Livonia (the northern half of modern Latvia, and the southern half of modern Estonia), driving the Swedes out of Finland. In 1714 the Russian fleet won the Battle of Gangut. During the Great Wrath most of Finland was occupied by Russian forces.
