Look at the map above and see if you can figure out which square each of the following 51 cities are in.
This is the world version of our Can You Find These 26 US Cities? post. Many of these cities sit close to a grid line, so look carefully.
Countries Where Nguyen Is The Most Common Surname
Nguyen (Nguyễn) is the most common surname in Vietnam, shared by an estimated 38–40% of the population.

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.
