The fact that Christianity is all over the world shows how it can adapt and have a lasting impact.

The First Christian Country

Christianity began with the teachings of Jesus around the first century AD. In 301 AD, something important happened in Armenia, a country in the Caucasus Mountains – it officially became the first country to choose Christianity as its main religion. This was a big deal because it marked a change in how Christianity spread, going beyond its starting point in the Levant and becoming a big deal worldwide.

The credit for Armenia choosing Christianity goes mostly to Gregory the Illuminator, an important person in Armenian history. Gregory, who was from Armenia, converted to Christianity and played a big role in introducing the faith to Armenia’s rulers, including King Tiridates III. By talking a lot about it and being really dedicated, Gregory convinced the king to make Christianity the official religion of Armenia.

Armenia picking Christianity as its main religion didn’t just affect its culture; it also showed the way for Christianity to keep spreading in the Caucasus and beyond, leaving a lasting mark on the global history of Christianity.

Where Christianity is Found Around the World

Right now, Christianity is all over the place, with followers in lots of countries on different continents. The exact count of Christian countries depends on what you mean by a “Christian country.” While many places have a lot of Christians, only a handful actually say Christianity is their main religion.

According to the Pew Research Center, Christianity is the main religion in about 157 countries and territories, making up almost two-thirds of all nations globally. This shows how big a role Christianity plays in shaping religion and culture around the world.

If we focus on countries that officially say Christianity is their main religion, it’s a smaller group – about 13 countries. This includes places like Armenia, Costa Rica, Denmark, England, Greece, Iceland, Malta, Monaco, Norway, Samoa, San Marino, Tonga, and Vatican City.
