Long ago, new leaders came to Syria.
They led their armies to new places. A great leader named Khalid helped them. He led his men through the dry desert.
Before this, the land was ruled by others. People spoke different ways to talk. Some spoke Greek and some spoke Aramaic.
There were many fights for the land. The new leaders won many battles. This changed how people lived in Syria.
Soon, the land had new rules. This was a very big change for the world. Do you like learning about old times?
Long ago, the land of Syria changed forever. Before this, the Byzantine Empire ruled the area. The Byzantines were part of the Roman world. People there spoke Greek or Aramaic. 
Between the years 634 and 638, new leaders arrived. These were the first Muslim caliphs. They led the Rashidun Caliphate. Two leaders named Abu Bakr and Umar led them. A famous general named Khalid ibn al-Walid helped too.
The conquest happened in three main steps. First, Muslim armies moved into the southern countryside. They met local groups living there. Second, the armies took major towns. This part of the war was very intense.
In the third step, the Muslims took the rest of the land. They moved into the north. This broke the power of the Byzantine Empire in Syria. After the war, Syria became part of a new region. It was called Bilad al-Sham. This change shaped the history of the world.
The Muslim conquest of Syria changed the map of the ancient world. This period took place between the years 634 and 638 CE. Before this, the Byzantine Empire ruled the land. The Byzantines were the successors to the Roman Empire. Most people in Syria spoke Greek or Aramaic. Some Arab groups, like the Ghassanids, lived there too. The Ghassanids were Christian and served the Byzantine Empire. 
The conquest was led by the Rashidun Caliphate. This was the first group of leaders after the prophet Muhammad. The first two leaders were Abu Bakr and Umar ibn al-Khattab. A very important general named Khalid ibn al-Walid also led the armies. Before the big conquest, there were smaller fights. One was the Battle of Mu'tah in 629 CE. In that battle, the Muslim army was defeated. However, Usama ibn Zayd led a successful raid in 632 CE.
Historians divide the conquest into three main parts. The first part began in late 633 or early 634. Muslim forces moved into the southern countryside first. They met local groups living in those tribal areas. During this phase, the armies mostly avoided big cities. They focused on the lands where nomadic tribes lived. This helped the Muslim state gain more control. 
The second phase happened from 634 to 636. This was a very active time for the war. General Khalid ibn al-Walid arrived to help the armies. He made a difficult march across the Syrian Desert. He even traveled for six days without any water. During this time, the Muslim armies captured major towns. The Byzantine Emperor Heraclius tried to respond to these moves.
The final phase happened between 637 and 648. The Muslim armies took the rest of the countryside. They moved into northern Syria to take individual towns. This broke the power of the Byzantine Empire in the region. After the fighting ended, Syria became a new province. It was known as Bilad al-Sham. This new rule brought many changes to the land.
The Muslim conquest of Syria was a major series of military campaigns. These events took place between 634 and 638 CE. The conquest was led by the Rashidun Caliphate. This was the first political state following the death of the prophet Muhammad. The expansion was part of the wider Arab–Byzantine wars. This conflict changed the political map of the Middle East forever. It brought the region under Arab Muslim rule. The territory eventually became known as the province of Bilad al-Sham.
Before the conquest, the Byzantine Empire controlled the region. The Byzantines were the successors to the Roman Empire. They had ruled Syria for seven centuries. The land was politically divided into two main provinces. Syria proper stretched from Antioch and Aleppo to the Dead Sea. The province of Palestine lay to the west and south of the Dead Sea. Most people in these areas spoke Greek or Aramaic. Some Arab populations also lived there. The Ghassanids were a Christian Arab tribe. They served as foederati, or allies, to the Byzantine Empire. Their king, Jabala ibn al-Ayham, ruled from the capital at Bostra. 
The Byzantine defenses were not prepared for this specific challenge. Emperor Heraclius had recently defeated the Sassanid Persians. He had rebuilt Byzantine authority in the region after a long war. He set up defense lines from Gaza to the Dead Sea. However, these lines were mostly to protect against bandits. The main Byzantine armies were concentrated in northern Syria. They were focused on the Sassanid Persians. This left the southern desert borders more vulnerable. Muslim forces could advance from the desert and reach Gaza easily. This gap in the defense allowed the initial invasion to succeed.
There were military clashes before the full conquest began. In 629 CE, the Battle of Mu'tah occurred near the Jordan River. Muslim forces fought the Byzantines and their Ghassanid allies. The Muslim army was defeated in this battle. However, the commander Khalid ibn al-Walid saved the remaining forces. Later, in 632 CE, Usama ibn Zayd led a successful raid. This was the first Muslim force to successfully invade Byzantine territory. After Muhammad died in 632, Abu Bakr became the first Caliph. He worked to unite the Arab tribes during the Ridda wars. By 633, Arabia was united under the central authority in Medina. 
Historians generally divide the conquest into three distinct phases. The first phase occurred from late 633 to early 634. During this time, Muslim forces targeted the southern, tribal countryside. They avoided large urban centers and major agricultural areas. They focused on territories held by nomadic or semi-settled tribes. This phase was described by some historians as mere "pinpricks" along the frontier. The goal was to bring all Arab tribes under the control of Medina. The second phase lasted from 634 to 636. This was a much more intense period of warfare.
The second phase saw the arrival of the general Khalid ibn al-Walid. He moved from the Iraqi frontier to join the Syrian armies. He completed an unconventional march across the Syrian Desert. This trek included six days of traveling without any water. During this stage, the Muslim armies captured major towns. This caused the Byzantine emperor to respond with stronger military force. The third and final phase lasted from 637 to 648. The Muslim armies occupied the remaining countryside. They moved into northern Syria to reduce individual towns one by one. This final stage broke the imperial power of the Byzantines in the region. 
The conquest had a massive impact on the history of the region. It shifted control from the Byzantines to the Rashidun Caliphate. This change led to the development of Bilad al-Sham. The conquest was a key part of the creation of a massive empire. Within a few decades, the Muslim state would become one of the largest in history. This process began with the confrontations in the Syrian desert. The movement of these armies changed how people lived and how governments functioned. It connected the Arabian Peninsula to the wider Mediterranean world.
