Charted: How Economic Power Shifted Over 200 Years
Published on August 4, 2026
Over the last 200 years, economic leadership has shifted from China to the British Empire, then to the United States, and increasingly back toward Asia.
This streamgraph tracks how the share of global gross domestic product (GDP) held by major economies changed from 1820 to 2025. The visualization incorporates the latest available data from the Maddison Project Database, the COLDAT Colonial Dates Dataset, and the IMF’s World Economic Outlook.
Pax Britannica and the European Years
Britain was the first country in the world to industrialize. As a result, the British Empire became the world’s preeminent superpower during the 19th century, an era sometimes known as Pax Britannica because of the relative absence of conflict between the major powers.In 1845, the British Empire, on which the sun famously “never set,” contributed nearly one-quarter (23.8%) of global GDP. India was the empire’s most economically significant possession before gaining independence in 1947.
The table below shows each economy’s peak share of world GDP, the year it reached that level, and its share in 2025:
The rest of Europe’s fortunes followed a similar trajectory. The French Empire reached its peak share in 1858, at 6.6%, while Germany peaked at 8.8% in 1913, on the eve of the First World War.
Following decades of war and declining influence on the world stage, several European economies joined together in the European Union. The bloc contributed 17.9% of global GDP in 2007, ahead of the global financial crisis, though its share later declined and was further reduced by the UK’s withdrawal in 2020.
The Fall of Empire and the Rise of the U.S.
If the 19th century was the British century, the 20th was the American century. Like Britain before it, the U.S. became the world’s largest exporter for a time.World War II marked a turning point in global economic leadership. By 1944, the U.S. accounted for 29.7% of world GDP, the highest share reached by any economy in the modern period covered by this dataset.
American economic dominance was supported by high-value industries and the country’s central role in global finance, manufacturing, and trade.
The U.S. also continues to dominate rankings of the world’s largest and most profitable companies today. It also is still the undisputed economic powerhouse in nominal GDP terms.
The Asian Century
For centuries, China was a center of the global economy. Political instability and its failure to keep pace with European industrialization contributed to a long decline in its share of world GDP during the 19th and 20th centuries.Beginning in the late 20th century, economic reforms and China’s emergence as a global manufacturing hub helped it regain lost ground. By 2025, China accounted for 21.8% of world GDP, or more than one-fifth of the total.
The full dataset below shows each economy’s share of world GDP for every year from 1820 to 2025:
Together, China and India accounted for 30.8% of global GDP in 2025. Their large populations and lower production costs give both countries greater weight when output is measured using purchasing power parity.
Whether this shift continues will depend partly on how China addresses demographic pressures similar to those facing Japan and the European Union, as well as broader challenges related to productivity and economic growth.
