* Some of the states that were created: Austria, Poland, Czechoslovakia, Hungary, Lithuania, Latvia and Yugoslavia
* Self-determination was taken into account in most cases however it was sometimes difficult as different nationalities, racial groups and linguistic groups where scattered across many different areas
* In some cases the ethnic groups were so intermixed that it was impossible to separate them. There was no point in creating an ethnically homogenous state which then could not survive due to lack of trade routes, natural resources, oceans and rivers. Therefore choices had to be made by the allies about whether self-determination was more important or if it was the economic stability of each state.
* An independent Polish state was created; the Polish Corridor was created to give Poland access to the Baltic Sea; Danzig became a free city to maximize trade opportunities
* Minorities could appeal to the League of Nations which provided a Minorities Commission
* Poland and Czechoslovakia fought over the Teschen area as it had important rail connections and coal resources
* Czechoslovakia, Romania and Yugoslavia realised their vulnerability and so decided to form the Little Entente in 1921
