Reasons For Muslim Conquests of the Persian and Byzantine Empires
During the era of the Rashidun Caliphate, Muslim armies fought simultaneously against two superpowers of the time, the Byzantine Empire and the Persian Empire. These warriors defeated both adversaries and expanded their rule from today’s Iran in the east to Libya in the west and Turkey in the north. During these campaigns against the superpowers of the time, Muslim forces remained victorious in almost every major battle.
It is astonishing
for many people how a newly formed state achieved these successes in such a
short period. It happened even though the Persian and Byzantine empires got assistance
from their Arabian vassal tribes and even cooperated against Muslims on some occasions
(e.g. the Battle of Firaz near the Iraq-Syria border).
Reasons for Early Muslim Conquests
Following
are some important reasons that made the Early Muslim conquests possible.
New Religion
The most important factor that enabled the transformation of the people of Arabia from Bedouins to a superpower is their new religion - Islam. Before Islam, Arabs always remained disorganized and split into tribes. Islam united the Arab tribes under one leadership for the first time, which increased their strength.

Arabs were
always known for their courage and fighting spirit. However, Islam enhanced their
courage and bravery by inculcating the spirit of martyrdom for religion. Under
this spirit, Muslims fought vigorously for a noble cause (to spread Islam in
other parts of the world) without even fearing the superpowers of the time.
Leadership Qualities
The leadership
qualities of early Muslim rulers are also a reason for these early Muslim
conquests. Abu Bakr (RA) became the first caliph after the death of Prophet
Muhammad (PBUH). At that time, many Arab tribes revolted against the caliphate.
Abu Bakr not only launched expeditions against these rebel tribes but also
started campaigns against the Persian and Byzantine empires to prevent them
from using the inner conflict of Arabia in their interests. Soon, Muslim armies
crushed the rebellion and achieved initial successes against the Persian Empire
and Byzantines during his tenure of just over 2 years.
During the
reign of Umar bin Khattab (RA), Muslims conquered the entire Persian Empire and
also took the areas of the Levant, Egypt, and Armenia from the Byzantines. Umar
not only played a vital role in the conquest of Persia and the Levant but he
also consolidated Muslim rule in the conquered areas by spreading Islam in these areas.
Great Military Generals
Khalid bin Walid
The greatest Muslim general of the time was Khalid bin Walid (RA) who received the title of Saifullah (Sword of Allah) from Prophet Muhammad (PBUH) for his bravery and military genius. Khalid played a major role in the conquest of Iraq (the Arabian part of the Persian Empire) and the Levant.
On several occasions, he defeated his opponent even many times higher in number than
his army. He was an expert in desert warfare techniques, focusing on speed and
surprise attacks. The enemy remained clueless over his skill, wisdom, and
attacks with lightning speed.

Weaknesses of Romans and Persians
Despite the
leadership and military qualities of Muslims, there is also no doubt that the
Persian Empire and Byzantine Empire had weaknesses due to the long
Byzantine-Sassanid War of 602-628. The war ended with neither opponent taking
any area of its foe but it weakened both the empires militarily and
financially. This factor also assisted the newly established Caliphate in defeating
both empires simultaneously.
Apart
from that, both empires didn’t take the emerging Muslim power seriously at the
beginning of the conflict. They considered Muslim Arabs similar to the nomadic
tribes of the past, only capable of fighting in deserts. They could not
calculate their new strength in time, which later proved disastrous for both
these empires.
