The immediate goal was political submission rather than universal forced conversion of individuals. People of the Book (Christians and Jews) could remain as dhimmis, paying the jizya poll tax and accepting restrictions; polytheists often faced conversion or death. Rules of war prohibited killing non-combatants in principle, regulated booty, prisoners, truces, and safe-conduct.\u2060<\/p>\n\n\n\n<p>Early Muslim chroniclers and legal texts framed the Rashidun and Umayyad campaigns as fulfilling divine command, ending opposition to the final revelation, and establishing justice against the Byzantine and Sassanid empires. Material incentives (booty, land, status) coexisted with religious ones, as in most pre-modern expansions.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">How was this succesful?<\/h4>\n\n\n\n<p>The rapid conquests of the Levant, Egypt, and later North Africa and the Sassanid realm (630s\u2013650s) succeeded because of a rare combination of opponent weakness and Arab strengths:<\/p>\n\n\n\n<p>Exhaustion of the two great powers: The Byzantine and Sassanid empires had just finished a devastating 25-year war (602\u2013628). Both were depleted in manpower, treasury, and cohesion. The Sassanids then suffered succession crises and civil strife after Khosrow II\u2019s overthrow. Byzantium under Heraclius recovered territory but remained strained.\u2060<\/p>\n\n\n\n<p>Internal divisions and unpopular rule: In Byzantine Syria and Egypt, many local Christians (especially Monophysites\/Copts) resented Constantinople\u2019s religious policies and heavy taxation. This reduced willingness to fight hard for the imperial cause. Sassanid rule faced similar strains with subject populations. Arab forces often offered surrender terms (jizya\/tribute, retention of local administration and religious practice) that were preferable to continued resistance.\u2060<\/p>\n\n\n\n<p>Mobility, cohesion, and morale: Arab armies excelled at desert and open-terrain warfare, using camel transport for rapid movement and light cavalry for maneuver. Unified under the early caliphs after the Ridda wars, they had high motivation from religious ideology, tribal bonds, prospects of booty, and effective leadership (notably Khalid ibn al-Walid). They could concentrate forces and exploit terrain better than the more rigid, multi-ethnic imperial armies. Key battles like Yarmouk (636) and Qadisiyyah demonstrated this.\u2060<\/p>\n\n\n\n<p>Strategic opportunism and adaptability: Initial campaigns often faced depleted garrisons. Victories created momentum; many cities surrendered rather than endure long sieges. Muslim forces adapted quickly, incorporating local auxiliaries and maintaining logistics across long distances.<\/p>\n\n\n\n<p>Historians (e.g., Fred Donner and others) emphasize that the decisive factor was the creation of a cohesive Arabian state with an expansionist ideology at precisely the moment the two regional superpowers were weakest. Superior arms were not the story\u2014timing, mobility, unity, and the opponents\u2019 exhaustion were.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The conquest of Palestine\/Levant was military (Yarmouk, multi-year sieges), not a merchant-driven process like much of maritime SE Asia\/Indonesia.
