3. Knowledge • We have better maps today because our knowledge of the world has increased due to: • Exploration of the world • Technology such as satellites • GIS mapping software for computers

4. Place Names • Over time the names of places change. Some examples are: • Formosa - Taiwan - Republic of China • Palestine - Israel - West Bank and Gaza Strip

5. Boundaries • The boundaries of countries change for many reasons such as: • Decolonization • Wars • Countries break into smaller countries because people want self rule • Intervention of the United Nations

9. Wars • The boundaries of countries are often redrawn at the end of wars. At the end of World War I and World War II the boundaries of many countries in Europe changed.

11. Self Rule • In the early 1990s the Soviet Union broke apart peacefully and many countries regained independence.

14. United Nations • In 1948, the United Nations created the country of Israel as a homeland for Jewish people who had been persecuted in WWII. The Muslim countries around Israel attacked the new country but lost three wars in 1948, 1967, and 1973.
