History of Islam

This topic surveys the history of Islam from its origins in seventh-century Arabia through the formation of its law, theology, and traditions to its development as a worldwide religion.

Definition

The study of the historical development of Islam, its sources, schools, and institutions, from its origins to the modern period.

Scope

It covers the career of Muhammad and the Qur'an, the early conquests and caliphates, the emergence of Sunni and Shia branches, the development of Islamic law (sharia), theology (kalam), and Sufism, and the modern transformations of Muslim societies. The treatment is historical and descriptive, addressing texts, institutions, and scholarly debates without endorsing or contesting Islamic claims.

Core questions

• How did Islam originate and spread in its first centuries?
• How did the Sunni–Shia division and the schools of law and theology arise?
• What roles did the Qur'an, hadith, and jurisprudence play in shaping the tradition?
• How has Islam been reshaped by modern political and intellectual change?

Key theories

Islam as a world civilization

Marshall Hodgson's interpretation of Islamic history as the development of a distinctive world civilization, integrating religion, society, and culture across a vast and diverse region.

The early 'believers' movement

Fred Donner's revisionist thesis that the earliest community was an ecumenical movement of monotheist 'believers' whose distinctively Islamic identity crystallized somewhat later than traditional accounts suggest.

History

Islam emerged in early seventh-century Arabia around the prophet Muhammad and the Qur'an, expanded rapidly under the early caliphates, developed its law, theology, and Sufi mysticism over the following centuries, divided into Sunni and Shia and numerous schools, and underwent profound reform and reinterpretation in the modern era.

Debates

Reliability of the traditional account of Islamic origins

Scholars debate how far the classical Muslim sources, written down later, accurately preserve the events of the earliest period, and how to use non-Muslim and documentary evidence.
