The world's faithful account for 83% of the global population; the great majority of these fall under twelve classical religions—Baha'i, Buddhism, Christianity, Confucianism, Hinduism, Islam, Jainism, Judaism, Shinto, Sikhism, Taoism, and Zoroastrianism. These twelve religions are the most prominent spiritual traditions that still exist. There are many smaller or less well-known religions. However, due to how much (or how little) different religions are represented in different communities, the layperson might not know much about the beliefs and traditions held by religious people worldwide. Infoplease is here to help with our overviews of nine of these classical religions.
Judaism
Judaism is a strictly monotheistic religion practiced by the Jewish people, an ethnic and religious nation descended from the historic peoples of Israel and Judah. Judaism as it would be recognized today originated in the Middle East in at least the 500s BCE, although certain religious traditions or beliefs can be traced back much further. Its adherents have long faced persecution from dominant religious groups around them. The Roman Empire destroyed the Second Temple, the center of Judaism, and the nation was scattered. Through to the modern day, Jews have been the victims of intense violence and discrimination. All the same, Judaism has persisted and remains one of the most visible and widely practiced religions in the world.

Christianity
Christianity is a monotheistic religion centered around the personage of Jesus of Nazareth, or Jesus Christ. Christianity arose in the 30s–50s CE as a religious offshoot of Judaism based on the teachings of Jesus, who was himself Jewish. Early Christianity rejected many of the social, cultural, and religious institutions of Judaism and pursued radically different strains of spiritual thought. Within a century a recognizable Church was founded. The texts of the faith and its most important creeds were codified in the 300s CE. Despite persecution, Christianity became the state religion of the Roman Empire and all of its inheritors, and in the time since the different Christian denominations have collectively become the largest faith in the world by a wide margin.

Islam
Islam is a strictly monotheistic faith founded by the prophet Muhammad in the year 607 in present-day Saudi Arabia. His teachings, collected in the Quran, claim common descent with many Jewish and Christian beliefs. Muhammad preached his faith in the city of Mecca despite opposition from local polytheists, and quickly built a religious community of early Muslims. The community was forced to relocate to Medina in 622, after which the group codified and began their expansion across the Arabian peninsula. Nearly all of Arabia converted to Islam by 632, the year of Muhammad's death, and in the years since it has grown to become the world's second largest religion, mostly concentrated in the Middle East and Southeast Asia.

Baha'i
Baha'i is the youngest major world religion, founded in 1863 by the prophet Bahá'u'lláh. Baha'i grew out of the earlier religion of Babism, whose founder the Bab presaged the coming of another great prophet like the coming of Muhammad. Baha'i originated in Iran, although its current center is in Haifa, Israel. Baha'i is a monotheistic religion, but it teaches that religious truth is manifested and revealed by the founders of all the major world religions, including Jesus Christ and the Buddha. Baha'is believe that the different cultural interpretations of religion all have the same goal, and they strive for prosperity across faiths. There are around eight million Baha'is today, who indirectly vote for the leaders of their religion every few years.
Zoroastrianism
Zoroastrianism is perhaps the world's oldest monotheistic religion, founded by the Persian prophet Zoroaster. It is first recorded in the 500s BCE, but many historians believe it was founded as early as the 900s BCE. Zoroastrianism became the dominant religion of the vast Achaemenid Empire of Persia, and it continued to play an important part in the region until the ascent of Islam in the 700s CE. Many credit Zoroastrianism with affecting the development of other major religions. Zoroastrianism declined through the medieval era, and today there are fewer than 200,000 Zoroastrians as of the last reputable survey. However, there are some indications that many Kurds are converting to Zoroastrianism, which they see as an ancestral religion, which may reverse the long declining population.
