In the past century, roughly 100 new countries have emerged. The exact number can vary based on how one defines “new country” (e.g., full sovereignty, international recognition) and the specific timeframe considered. Here is an overview of key periods of new country formation:

Post-World War I (1918-1945)

• After World War I, several countries gained independence or were re-established as empires dissolved, such as Finland, Poland, Estonia, Latvia, Lithuania, and Yugoslavia.
• The dissolution of the Ottoman Empire also led to the formation of Turkey and mandates that later became independent states in the Middle East (e.g., Iraq, Syria).

Post-World War II and Decolonization (1945-1970s)

• Decolonization in Asia and Africa: Many new countries emerged as former European colonies gained independence, particularly in the 1950s-1970s.
  • Asia: India, Pakistan, Myanmar, Indonesia, Malaysia, Sri Lanka, and others.
  • Africa: Most countries gained independence in this period, including Ghana, Nigeria, Kenya, Algeria, and dozens of others.
• Middle East & Caribbean: New countries like Israel, Jordan, and several Caribbean island nations also emerged.

Post-Cold War (1990s-Present)

• Collapse of the Soviet Union (1991): Resulted in the independence of 15 republics, including Russia, Ukraine, Belarus, the Baltic States (Estonia, Latvia, Lithuania), and Central Asian republics.
• Breakup of Yugoslavia (1990s-2000s): Led to the formation of new countries like Slovenia, Croatia, Bosnia and Herzegovina, North Macedonia, Montenegro, Serbia, and later Kosovo (not fully recognized by all countries).
• Dissolution of Czechoslovakia (1993): Created two separate countries, Czech Republic and Slovakia.
• New Nations in Africa: Eritrea (1993, from Ethiopia) and South Sudan (2011, from Sudan).

Other Notable Formations

• Timor-Leste (East Timor): Gained independence from Indonesia in 2002.
• Palau and Micronesia: Became independent from the United States-administered Trust Territories in the 1990s.

In summary, over 100 new countries have appeared in the last century, primarily due to decolonization, the collapse of empires, and geopolitical shifts. The majority of these new nations were formed in the wake of World War II and during the decolonization period of the mid-20th century, as well as the dissolution of the Soviet Union and Yugoslavia in the early 1990s.
