How did the peace treaties both follow and violate the principle of self-determination

Answer: self-determination was placed in only for Europe, and not in the outer territories and this came to be known as the system of mandates.

Explanation: The system of mandates led to freeing some of the colonies under German control only for them to be put under control of the allies such as England and France.

Self-determination is a political principle an is the process by which a group of people form their own state and choose their own government. In World War I the Allies accepted self-determination as a peace aim.

In Eastern Europe, when the German, Austrian, and Russian empires fell, many nations emerged and this self-determination led to the creation of many nations such as Czechoslovakia, Poland, the Baltic states, and Yugoslavia. However, by creating mandates outside Europe, the treaties ignored non-European peoples' right to self determination.
