British Empire

The British Empire remains the largest empire in history by land area and population, controlling 26.35% of the world's total land and governing 23% of the global population at its 1920 peak. Its reach exceeded the Mongol Empire's land coverage by over 2% and its population share—a factor of 1.3 more than the Roman Empire's 21%—underscores its unmatched demographic dominance. The empire's enduring legacy includes the English language, now spoken by 1.5 billion people, and the Westminster parliamentary system adopted by 50+ nations, while its global trading networks fueled the Industrial Revolution, transforming economies worldwide.
