Muslims are people who adhere to Islam, a monotheistic religion belonging to the Abrahamic tradition. They consider the Quran, the foundational religious text of Islam, to be the verbatim word of the God of Abraham as it was revealed to Muhammad, the main Islamic prophet. Alongside the Quran, Muslims also believe in previous revelations, such as the Tawrat (Torah), the Zabur (Psalms), and the Injeel (Gospel). These earlier revelations are associated with Judaism and Christianity, which are regarded by Muslims as earlier versions of Islam. The majority of Muslims also follow the teachings and practices attributed to Muhammad (sunnah) as recorded in traditional accounts (hadith).
The world's principal religions and spiritual traditions may be classified into a small number of major groups, though this is not a uniform practice. This theory began in the 18th century with the goal of recognizing the relative levels of civility in different societies, but this practice has since fallen into disrepute in many contemporary cultures.

Religion has been a major influence on the societies, cultures, traditions, philosophies, artistic expressions and laws within present-day Europe. The largest religion in Europe is Christianity. However, irreligion and practical secularisation are also prominent in some countries. In Southeastern Europe, three countries have Muslim majorities, with Christianity being the second-largest religion in those countries. Ancient European religions included veneration for deities such as Zeus. Modern revival movements of these religions include Heathenism, Rodnovery, Romuva, Druidry, Wicca, and others. Smaller religions include Indian religions, Judaism, and some East Asian religions, which are found in their largest groups in Britain, France, and Kalmykia.
Christianity in Africa first arrived in Egypt in approximately 50 AD. By the end of the 2nd century it had reached the region around Carthage. In the 4th century, the Aksumite empire in modern-day Ethiopia and Eritrea became one of the first regions in the world to adopt Christianity as its official religion. The Nubian kingdoms of Nobatia, Makuria and Alodia followed two centuries later. From the late fifth and early sixth century, the region included several Christian Berber kingdoms. Important Africans who influenced the early development of Christianity and shaped the doctrines of Christianity include Tertullian, Perpetua, Felicity, Clement of Alexandria, Origen of Alexandria, Cyprian, Athanasius and Augustine of Hippo.
Growth of religion involves the spread of individual religions and the increase in the numbers of religious adherents around the world.

Statistics commonly measure the absolute number of adherents, the percentage of the absolute growth per-year, and the growth of converts in the world.

Based on the numbers of adherents, the Eastern Orthodox Church is the second largest Christian communion in the world, after the Roman Catholic Church, with the most common estimates of baptised members being approximately 220 million. The numerous Protestant groups in the world, if taken all together, substantially outnumber the Eastern Orthodox, but they differ theologically and do not form a single communion.
Adherents of Islam constitute the world's second largest religious group. A projection by the PEW suggests that Muslims numbered approximately 1.9 billion followers in 2020. Studies in the 21st century suggest that, in terms of percentage and worldwide spread, Islam is the fastest-growing major religion in the world, mostly because Muslims have more children than other major religious groups. Most Muslims are either of two denominations: Sunni or Shia. Islam is the majority religion in several subregions: Central Asia, Western Asia, North Africa, West Africa, the Sahel, and the Middle East. The diverse Asia-Pacific region contains the highest number of Muslims in the world, surpassing the combined Middle East and North Africa.
The decline of Christianity in the Western world is the decreasing Christian affiliation in the Western world. While most countries in the Western world were historically almost exclusively Christian, the post-World War II era has seen developed countries with modern, secular educational facilities shifting towards post-Christian, secular, globalized, multicultural and multifaith societies.
Oriental Orthodox Churches are the churches descended from those that rejected the Council of Chalcedon in 451. Despite the similar name, they are therefore a different branch of Christianity from the Eastern Orthodox. Oriental Orthodoxy consists of several autocephalous and autonomous jurisdictions holding a single set of beliefs and united in full communion. However, they each have their own separate rites, and there are significant differences between their respective practices. Thus, there is more internal diversity of practice among the Oriental Orthodox than among the Eastern Orthodox.
