Answer:
Spain, Greece, and the Netherlands
Explanation:
The maps show us the alliances that existed before World War I. We can see that Triple Entente (painted in black) was composed of Great Britain, France, and Russia. They made an informal agreement, and these countries entered the war as Allied Powers. The map shows that the other alliance (hatched) was the Triple Alliance composed of Germany, Italy, and the Austria-Hungarian empire. They made Central powers in the war.
The counties presented in white on the map are those that did not belong to any alliance. The three countries that did not belong to any alliance which we can see are:
- Spain – Spain did not ally with anyone, and it managed to remain neutral during the war. The King and prime minister did not want to get involved and wanted to try to benefit at the end of the war from the winner, no matter who it was. However, they did not and they had many economic problems. Their neutrality continued but ended in the Spanish Civil War
- Greece – Greece had no previous alliances before the war. They also wanted to remain neutral but did not manage to do so. The King and prime minister had different ideas, and there was disagreement. They entered the war in 1917, on the side of the Allies.
- The Netherlands – the Netherlands had neutral international affairs before the war and made no alliances, as seen by the map. Despite them being in the west, in the middle of the countries affected by the war, they managed to stay neutral during the whole war. The army guarded the border and there were mines on the coast to protect the land. They were also bombed and attacked from both sides during the war (allegedly by accident). Not everyone in the country wanted to remain neutral, but the Netherlands endured.
