Europe experienced numerous geographic changes during the 20th century. Major events such as World War I, World War II, and the Cold War produced enough upheaval to eliminate powerful empires and create new nations while dividing others. For this task, you will document the geographic changes that occurred in the 20th century to a present-day European country of your choice. Select one of the three nations listed below, and recall how its current borders came to be by reviewing its history:

Germany
Czech Republic
Croatia
Recall what you have learned about the history of Europe during the 20th century, and gather material online about the country you chose.

Then, in two to three paragraphs, explain how the events of the 20th century led to geographic changes in the country.

Be sure to explain what was happening to the country as a result of World War I, World War II, the Cold War, and the collapse of the Soviet Union. Keep in mind that the country may not have existed at a particular time in the 20th century. If this is the case, explain what was happening at that time in the area where the present-day country is located.
Elaborate on how and why these major historical events changed the country.

I really need help. Thanks!
