How did the peace treaty ending World War I both follow and violate the principle of self-determination ?

One of the goals that Woodrow Wilson wanted to accomplish as the Allies prepared to develop a peace treaty ending World War I was to allow people in many countries to be ruled by their own people. In some ways, this was accomplished. Polish people ran the government of Poland. The southern and eastern Slavic groups controlled and ran the governments of Yugoslavia and Czechoslovakia. In these countries, the principle of self-determination was very evident.

However, self-determination didn’t exist everywhere. The splitting of the Ottoman Empire didn’t lead to people being ruled by their own people. After World War I ended, much of the Middle East was given to Great Britain and France. These countries ruled the Middle East for many years before some of these countries became independent.

Self-determination was one of our goals in World War I, but it didn’t occur everywhere after the war ended.
