Countries With A Larger Military Than The UK In 1900 vs 2026

The map above supposedly comes from the IISS (The International Institute for Strategic Studies) and shows which countries in 1900 (using modern borders) had more active miliary personnel than the United Kingdom in 1900 compared to today.

Getting data for the numbers in 1900 is actually difficult (can’t find them published online), but Data Is Beautiful has estimates that vary slightly from the map which you can see below:
