While it may feel like nations are set in stone, many of today’s nations only emerged in the past few decades. The formation of new countries is often driven by conflict, shifting borders, and the pursuit of sovereignty. Let’s explore the newest countries formed since 1990.
Today, statehood is typically defined by recognition from the United Nations (UN), which currently recognizes 193 member states and two observer states – Palestine and the Vatican. Over the last 40 years, 34 new countries have formed. The most recent is South Sudan, which gained independence from Sudan in 2011 after decades of civil war. Although South Sudan had previously achieved autonomy in 1956, tensions between the Muslim-majority north and Christian-majority south led to prolonged conflict. It was not until a 2011 referendum – where 98% of voters supported independence – that the country officially became the world’s newest nation.
The above map, created by Visual Capitalist using data from the World Population Review, clearly illustrates the timeline and geographic distribution of these newly formed countries. The most common reasons for state formation are the secession or the dissolution of larger political entities.
Fifteen countries, the majority of which are new nations on this map, are located in Eastern Europe, formed during the dissolution of the Union of Soviet Socialist Republics (U.S.S.R.). Lithuania was formed in 1990, with 14 other countries (Armenia, Azerbaijan, Belarus, Estonia, Georgia, Kazakhstan, Kyrgyzstan, Latvia, Moldova, Russia, Tajikistan, Turkmenistan, Ukraine, and Uzbekistan) formed in 1991. However, the fall of the USSR also influenced the formation of other former communist nations. The fall of the USSR also influenced other former communist nations. For example, Czechoslovakia peacefully split into the Czech Republic and Slovakia in 1993, an event often referred to as the “Velvet Divorce.” The term references the Velvet Revolution of 1989, a non-violent movement that ended communist rule and led to the restoration of democratic governance in the country.
Likewise, another major event occurred in Yugoslavia, a larger former communist nation in Eastern Europe. Located between Austria to the north and Greece to the south, Yugoslavia became a socialist state following World War II. Yugoslavia was formed in 1918 and was never part of the USSR. However, ethnic tensions, political repression, and economic instability, similar to those of the USSR, led to its disintegration in the 1990s. This period was marked by a series of violent conflicts known as the Yugoslav Wars, in which several republics fought for independence against the central government in Belgrade. The wars were marked by complex ethnic violence, primarily among Serbs, Croats, and Bosniaks, and resulted in widespread devastation. By 2008, it had fractured into six (or arguably seven) independent countries: Slovenia, Croatia, Bosnia and Herzegovina, North Macedonia, Montenegro, Serbia, and Kosovo (partially recognized). The sovereign territory of Kosovo announced its independence from Serbia in 2008, but it has not yet been officially recognized by UN members. Today, these countries vary in population size, economy, and biodiversity, with Serbia being the largest and Slovenia the most economically developed.
Beyond former communist states, several other nations gained independence in the early 1990s. Namibia was recognized by the UN in 1990 after gaining independence from decades of South African rule. Similarly, Eritrea became independent in 1993 following a 30-year war with Ethiopia. Among the most widely recognized geopolitical changes is the reunification of Germany. Originally unified in 1871, Germany was divided into West Germany and East Germany after World War II. With the fall of the Berlin Wall in 1989, the two states were reunified in 1990. Many researchers argue that Germany should return to its original form rather than the formation of a new country. Few also question Yemen, which was formed by merging two previous nations, the Yemen Arab Republic and South Yemen.
Overall, the past few decades have reshaped the world map significantly. Each of these newly formed countries has its own story and path to independence. Together, they show how the world is always changing and how people continue to seek freedom, identity, and self-rule.
