This quiz asks for the 10 countries with the most deaths in World War I. The counts include soldiers and civilians. Historians give ranges, so every number in this quiz is approximate.
The list uses the states of 1914–1918. Two of the four empires at the top no longer exist.
How to play
The map shows no pins at the start. A numbered 1–10 rail lists the ranks you have not named yet.
Type a country name in the box at the bottom of the screen. The quiz accepts the name as soon as it matches.
A correct name puts the country on the map and shows its death toll.
You can name the countries in any order. Rank order does not matter.
The clock runs until you name all 10 countries, or until you give up.
What counts in this quiz
The quiz uses the states as they existed during the war. The Russian Empire, the Ottoman Empire and Austria-Hungary are answers.
Modern and short names still count as spellings. "Russia", "Turkey", "Austria" and "Hungary" are all accepted.
The counts include civilian deaths from famine, disease and the genocides inside the Ottoman Empire.
The quiz ranks countries by total deaths, not by deaths as a share of population.
What's not included — and why
The United States is not in the top 10. It entered the war in 1917 and lost about 117,000 people.
Deaths from the 1918 influenza pandemic are not part of the war counts, even though the war helped the disease spread.
Estimates differ between sources, most of all for the Ottoman Empire and Serbia. The quiz uses midpoints of the ranges that reference works give most often.
Good to know
World War I caused an estimated 15 to 22 million deaths.
Serbia lost a larger share of its population than any other country in the war — most estimates say more than 15%.
France lost about 4% of its population. Nearly every French town and village has a monument with the names of its dead.
The war dissolved four empires: the Russian, Ottoman, Austro-Hungarian and German empires all fell within a year of the armistice.
