As of 2016, there are 195 countries in the world. If you ask us, that's way too many. We have enough trouble remembering all 50 states, especially Delaware (what happens there?). So to help you get up to speed on your geography knowledge, we found 10 countries that you probably didn't even know exist. 

Nauru, Central Pacific Ocean
1. Nauru, Central Pacific Ocean

This 8-square-mile island is the smallest independent republic on earth, which is somewhat ironic given that it's the fattest country on the planet. About 95 percent of citizens here are overweight — an epidemic that started when the country began importing Western food.

Lesotho, Southern Africa

2. Lesotho, Southern Africa

If South Africa were a kangaroo, Lesotho would be the baby in its pouch. The landlocked Lesotho is completely surrounded by South Africa, and it's the only country in the world that sits 1,000 meters above sea level. 

Liechtenstein, Europe

3. Liechtenstein, Europe

This ritzy little European country is one of the wealthiest in the world. But hold your applause: The puny country has no army and only granted women the right to vote in 1981.

Seychelles, Indian Ocean
4. Seychelles, Indian Ocean

A collection of 115 islands comprise this country, which is home to about 92,000 citizens. The islands contain some of the most incredible biodiversity on Earth, so the country enforces strict environmental regulations. But hey, you can still sit on turtles.

Niue, Island Country

5. Niue, Island Country

In the South Pacific Ocean is the island country of Niue, affectionately known as "The Rock." Despite having a population of just more than 1,000 people, people here are still pretty good at rugby. New Zealand conducts most of their diplomatic affairs.

Mauritania, North Africa

6. Mauritania, North Africa

More people should probably know about Mauritania — slavery was legal here until 1981, and 10 to 20 percent of residents still live in slavery to this day, according to the U.N. And even those who don't live in slavery typically live on mere dollars per day.

Ivory Coast, West Africa
7. Ivory Coast, West Africa

This French-speaking country was once rich from its cocoa and coffee production, but religion-based civil wars in the 1990s slowed the country's progress considerably...And you probably thought Ivory Coast was just a nice stretch of beach.

Burkina Faso, West Africa

8. Burkina Faso, West Africa

This African country arguably has the world's funniest city names: Bouroum Bouroum, Gorom Gorom and Rambo, to name a few. A mostly agricultural society, sometimes drummers will accompany farmers into the fields to make their work a little more enjoyable.

Benin, West Africa

9. Benin, West Africa

Some say voodoo originated in Benin, which would make sense considering about 75 percent of people here still practice the religion. You can find gold, one of the country's primary exports, in the Atakora Mountains in the northern region of this French-speaking country.

Azerbaijan, Asia

10. Azerbaijan, Asia

Azerbajan, located along the Caspian Sea, is an oil-rich country that few have heard about. So to get some press, the country hosted the first European Games last year in its capital city, Baku. It backfired though, after international journalists started probing the country's questionable human rights record.
