Top 10 Countries That Disappeared In The 20th Century

Top 10 Countries That Disappeared In The 20th Century | Southern Hemisphere |
New nations seem to pop up with alarming regularity. At the start of the 20th century, there were only a few dozen independent sovereign states on the planet; today, there are nearly 200!

Amazing to see many of the countries and empires that are no longer around.  Also with the dissoution of many of the empires it lead's to many of the issues that were are dealiing with today.  Splitting the Austro-Hugaraian Empire after WWI along ethnic lines didn't really work and helped to lead to WWII.  The Germans in the Sudetenland in Czechoslovakia fro example.  See

 for the area of German population.

10 countries that have become nonexistent in the 20th century include Tibet, East Germany and Yugoslavia. These countries have died off because of ethic, religious and cultural falls that were quickly taken over by bigger and more powerful countries.

Essentially this article boils down to the issues of religion, ethnicity and nationalism.  People who are diverse and have different ideas generally cannot all live together under one rule and agree on everything, hence nations split and new ones form to cater to their own beliefs and similarities.

Manifest Destiny in 141 Maps

This data visualization project is a great way to demonstrate the geographic expansion of the United States.  This is much more interactive than the typical time lapse video since you can scroll through the maps and explore each map through the interactive features.

I really like the display of these changes in our country throughout the years. It's a great way of showing centuries of change into something easy to understand. This would help young students in a social studies class for sure.

i LOVE THIS! I can see this being such a valuable tool to use in a classroom. Students get the visual and written representation. Having the visual changes that took place in the United States is a better way to present to the students instead of them just reading a book. Will definitely save this article for future reference.

This is great idea. I wonder if I can use something like this for my project.
