During the 29-year rule of the Rashidun caliphate (632–661), Muslim armies significantly expanded the Islamic state beyond the Arabian Peninsula. Their conquests encompassed the following territories:

  • Iraq1
  • Syria1
  • Palestine1
  • Egypt1
  • Iran1
  • Armenia1

The expansion began following the riddah wars, which suppressed tribal uprisings within Arabia. The conquest of the Sasanian Empire in Iran was solidified by decisive victories at the Battle of al-Qadisiyyah (636/637) and the Battle of Nahavand (642). While Arab forces began raiding into North Africa (the Maghrib) after the conquest of Egypt in 642, systematic efforts to establish direct rule in that region were largely undertaken by the succeeding Umayyad dynasty rather than the Rashidun.123
