The video above shows a very simplified version of the 21-Year Long Great Northern War using Google Maps.
I was very much inspired to find a video map of the war because of the wonderful The Rest is History series on it.
Here’s more about the war:
The Great Northern War (1700–1721) fundamentally altered the power dynamics in Northern and Eastern Europe.
It involved primarily Sweden against a coalition of Denmark-Norway, Russia, Poland-Lithuania, and later Prussia and Hanover.
Here is a detailed summary covering its causes, major events, battles, and consequences:
Causes and Background
By the end of the 17th century, Sweden was one of the strongest military powers in Northern Europe, possessing territories around the Baltic Sea, including Finland, Estonia, Livonia, parts of modern-day Latvia, and significant holdings in Northern Germany.
Under King Charles XI, Sweden strengthened its position through administrative reforms and military modernization.
However, Sweden’s dominance sparked resentment among neighbouring states, which sought opportunities to reclaim territories and influence:
- Russia: Tsar Peter the Great wanted access to the Baltic Sea to facilitate Russia’s modernization and trade expansion.
- Denmark-Norway: Desired to regain territories lost to Sweden, especially areas such as Skåne and Holstein-Gottorp.
- Poland-Lithuania: Under King Augustus II (“Augustus the Strong“), sought to reclaim Livonia and strengthen royal authority weakened by internal conflicts.
These ambitions culminated in a coalition formed by Russia, Denmark-Norway, and Poland-Lithuania aimed at curbing Swedish power, triggering the outbreak of war in 1700.
Course of the War (1700–1721)
Initial Phase (1700–1706): Swedish Dominance
The early years of the war saw Sweden under the young and talented King Charles XII (ruled 1697–1718) achieve remarkable military successes:
- Battle of Narva (1700): Sweden defeated a numerically superior Russian army decisively, boosting Charles XII’s military reputation and temporarily crippling Russian morale.
- Invasion of Poland-Lithuania (1701–1706): Charles XII successfully campaigned against Augustus II, defeating Polish and Saxon forces in several battles, notably at Kliszów (1702). He eventually forced Augustus II to abdicate the Polish throne in favour of Swedish ally Stanisław Leszczyński in 1704.
- Treaty of Altranstädt (1706): Augustus II renounced the Polish throne, temporarily isolating Russia in the conflict.
Turning Point (1707–1709)
Confident from early victories, Charles XII shifted focus eastward towards Russia in an ambitious and ultimately disastrous campaign:
- Russian Campaign and Battle of Poltava (1709): Charles XII’s invasion of Russia suffered from severe logistical challenges, harsh winters, and inadequate supplies. In the decisive Battle of Poltava (1709), Peter the Great’s revitalized Russian army defeated Sweden decisively, dramatically shifting momentum in favour of the coalition. Charles fled to the Ottoman Empire, effectively removing Sweden’s strongest leader from active participation.
Final Phase (1709–1721): Decline of Swedish Power
After Poltava, Sweden faced invasions on multiple fronts:
- Russian advances: Russia captured Swedish territories in the Baltic provinces, notably Livonia, Estonia, and parts of Finland.
- Renewed Danish-Norwegian involvement: Denmark launched invasions against Swedish holdings in southern Sweden and Germany, though it experienced mixed success.
- Prussia and Hanover involvement: Joined the anti-Swedish coalition, further exacerbating Swedish defeats and territorial losses.
Key later battles and events included:
- Battle of Helsingborg (1710): Sweden successfully defended against Danish invasion, temporarily stabilizing its situation in southern Sweden.
- Battle of Gangut (1714): Russia’s naval victory demonstrated new naval dominance in the Baltic Sea.
- Siege of Fredriksten (1718): Charles XII was killed during this siege in Norway, leaving Sweden politically weakened and fragmented internally.

Consequences and Aftermath
The war significantly reshaped the geopolitical landscape of Northern Europe:
Sweden:
- Lost territories including Estonia, Livonia, Ingria, parts of Karelia, and territories in Northern Germany.
- Dramatic decline as a great European power; diminished influence and economy strained by war debts.
- Shifted from aggressive expansionism toward defensive neutrality.
Russia:
- Emerged as a major European power, gaining territories in the Baltics and access to the Baltic Sea.
- Founded St. Petersburg (1703), which became a significant political, military, and commercial centre, symbolizing Russia’s westward orientation and modernization.
Denmark-Norway:
- Minor territorial gains, particularly regaining control over Schleswig-Holstein-Gottorp, but failed to significantly weaken Swedish control over Scania.
Poland-Lithuania:
- Augustus II restored as king but Poland-Lithuania remained politically fractured and weakened.
Europe’s Geopolitical Impact:
- Balance of power shifted significantly; Russia emerged as dominant Eastern European power.
- Initiated the decline of Poland-Lithuania and Sweden as influential powers.
- Marked the beginning of the Russian Empire’s role as a significant participant in European politics.
Cultural and Economic Consequences:
- Accelerated Russia’s modernization under Peter the Great, who introduced Western customs, technologies, and administration.
- Sweden faced prolonged economic hardship and internal political instability.
