List of World War I puppet states

During World War I a number of countries were conquered and controlled. Some of these countries were subsequently given new names and new government leaders loyal to the conquering country. These countries are known as puppet states. Germany and the Ottoman Empire were the two countries with puppet states. The Allies had many more puppet states than all the Central Powers collectively: the United Kingdom had the largest empire in the world.

In addition, several countries captured land in the years leading up to the war, which then became puppet states; those states which are immediately relevant to the war are also included here.
