AD 632

Ridda wars

Abu Bakr begins multi-front Ridda campaigns

The rebellions shared no single cause: one tribe might follow a new prophet, another profess Islam but withhold tax, another resist rule it had never accepted.

Not one rebellion

After Muhammad’s death in 632 and the selection of Abu Bakr as caliph, opposition to Medina appeared across Arabia.

Some movements followed rival claimants to prophecy, others rejected taxation or Medinan political control, and some arose in places never previously under direct Medinan rule.

“Apostasy” reflects the terminology of later Muslim sources; modern historians stress that some opponents remained monotheists or Muslims while rejecting Medina’s taxes or authority.

Columns in every direction

Abu Bakr adopted the objective of extending the Medinan state’s authority throughout Arabia, and responded with military deployments and diplomacy together.

Khalid ibn al-Walid was dispatched with Muhajirun and Ansar toward Najd and the Banu Hanifa opposition in Yamama; Shurahbil ibn Hasana was sent toward the same broad theatre.

Other commanders were directed toward Bahrain, Oman, Mahra, Yemen, the Tihama coast and a rising near Medina — a distributed campaign rather than a single opening battle.

Negotiators as well as generals

Abu Bakr negotiated with tribal leaders at the same time, including a section of Banu Shayban, so submission, alliance and incorporation were pursued alongside battlefield defeat.

The year 632 is secure, but the sources preserve no reliable Gregorian launch day: a modern chronological study notes that the generals’ months and days are absent, and estimates roughly September for the broad dispatch.

The end is debated too — authoritative summaries place Arabia’s final reunification somewhere in 633–634, rather than on a secure day.

What the sources leave uncertain

The year 632 for the start is secure, but the sources do not preserve a reliable Gregorian launch day. A modern chronological study notes that the generals’ detailed months and days are absent and estimates roughly September for the broad dispatch.
Most detailed narratives were written down long after the events, and reconstructions that assign nearly every skirmish an exact modern date create false precision.
“Apostasy” reflects the terminology of later Muslim sources. Modern historians stress that some opponents remained monotheists or Muslims but rejected Medina’s taxes or political control, while others had never submitted to Muhammad.
The terminal date is also debated; authoritative summaries place Arabia’s final reunification sometime in 633–634 rather than on a secure day in June 633.
