Axiel Religion

Vom Ursprung und Ziel der Geschichte (The Origin and Goal of History), identified a number of key Axial Age thinkers as having had a profound influence on future philosophy and religion, and identified characteristics common to each area from which those thinkers emerged. Jaspers saw in these developments in religion and philosophy a striking parallel without any obvious direct transmission of ideas from one region to the other, having found very little recorded proof of extensive inter-communication between the ancient Near East, Greece, India and China. Jaspers held up this age as unique, and one which to compare the rest of the history of human thought to. Jaspers' approach to the culture of the middle of the first millennium BCE has been adopted by other scholars and academics, and has become a point of discussion in the history of religion.

In its later part, the "Axial Age" culminated in the development of monism and monotheism, notably of Platonic realism and Neoplatonism in Hellenistic philosophy, the notion of atman in Vedanta Hindu philosophy, and the notion of Tao in Taoism.

Middle Ages

The present-day world religions established themselves throughout Eurasia during the Middle Ages by: Christianization of the Western world; Buddhist missions to East Asia; the decline of Buddhism and rise of Hinduism in the Indian subcontinent; and the spread of Islam throughout the Middle East, Central Asia, North Africa and parts of Europe and India.

During the Middle Ages, Muslims were in conflict with Zoroastrians during the Islamic conquest of Persia; Christians were in conflict with Muslims during the Byzantine-Arab Wars, Crusades, Reconquista and Ottoman wars in Europe; Christians were in conflict with Jews during the Crusades, Reconquista and Inquisition; Shamans were in conflict with Buddhists, Taoists, Muslims and Christians during the Mongol invasions; and Muslims were in conflict with Hindus and Sikhs during Muslim conquest in the Indian subcontinent.

Many medieval religious movements emphasized mysticism, such as the Cathars and related movements in the West, the Bhakti movement in India and Sufism in Islam. Monotheism reached definite forms in Christian Christology and in Islamic Tawhid. Hindu monotheist notions of Brahman likewise reached their classical form with the teaching of Adi Shankara.

European colonisation during the 15th to 19th centuries resulted in the spread of Christianity to Sub-Saharan Africa, the Americas, Australia and the Philippines. The 18th century saw the beginning of secularisation in Europe, rising to notability in the wake of the French Revolution.

In the 20th century, the regimes of Communist Eastern Europe and Communist China were explicitly anti-religious. A great variety of new religious movements originated in the 20th century, many proposing syncretism of elements of established religions. Adherence to such new movements is limited, however, remaining below 2% worldwide in the 2000s. Adherents of the classical
