A video about the transition from the pre-WW1 borders to the post-WW1 borders and how the time period in-between the end of the war in 1918 and the treaties of Saint-Germain and Trianon in 1920 and 1921 was basically a power vacuum followed by a power struggle. In the same way that things usually don’t begin overnight (“Rome wasn’t built in a day”), they usually don’t collapse overnight either (“Rome didn’t collapse in a day”).

Further viewing for the interested: The treaty of Saint-Germain and The treaty of Trianon.
