Introduction
The 7th century was a time of profound historical significance, marked by extraordinary events that left an indelible imprint on human civilization. One of the most iconic occurrences was the birth of Islam in the 7th century, with the Holy Prophet Muhammad’s (Peace be Upon Him) revelations and the subsequent rapid spread of the faith across the Arabian Peninsula. Another notable event was the Battle of Tours in 732, where Charles Martel’s Franks halted the Islamic expansion into Europe. Moreover, the 7th century witnessed the rise of the Tang Dynasty in China, a golden age of culture and innovation, while in India, the Gupta Empire’s intellectual achievements flourished. This century was a pivotal moment in human history, shaping the world as we know it today.
The Rise of Islam and the Hijra (Migration) of Holy Prophet Muhammad (PBUH)
The rise of Islam and the Hijra (Migration) of Holy Prophet Muhammad (PBUH) in 622 AD are pivotal events in Islamic history. Here are some unique facts about this period:
- The Year of Sorrow: Before the Hijra, last Prophet Muhammad (PBUH) experienced a year known as the “Year of Sorrow” (619 AD). He lost his wife Hazrat Khadijah and his uncle and protector Hazrat Abu Talib, which made him vulnerable in Makkah and contributed to his decision to migrate.
- The Covenant of Medina: Upon arriving in Medina, last Prophet Muhammad (Peace Be Upon Him) established the Covenant of Medina, a constitution that outlined the rights and duties of various religious and tribal groups. It is considered one of the earliest examples of a constitution in human history.
- The Lunar Calendar: The Islamic calendar, also known as the Hijri or lunar calendar, is based on the events surrounding the Hijra. It has 12 months of 29 or 30 days, making it about 11 days shorter than the Gregorian calendar. This calendar is still in use in the Islamic world today.
- The Qibla Change: Before the Hijra, Muslims prayed facing Jerusalem, but after the migration, the direction of prayer (qibla) was changed to the Kaaba in Makkah. This shift symbolized the independence and identity of the Islamic community.
- Economic and Social Changes: The Hijra marked a significant shift in the economic and social structure of the early Muslim community. In Medina, agriculture and trade thrived, and the community began to develop its distinct economic system based on Islamic principles.
- The Battle of Badr: One of the first major military conflicts involving the Muslims took place after the Hijra in the form of the Battle of Badr (624 AD). Despite being outnumbered, the Muslims achieved a decisive victory, which solidified their position in Medina and within the Arabian Peninsula.
- Migration of Early Followers: The Hijra was not limited to Holy Prophet Muhammad (Peace Be Upon Him) alone. Many early Muslims migrated to Medina, leaving behind their homes and belongings. This migration demonstrates their commitment to their faith and the message of Islam.
- Interfaith Relations: In Medina, Holy Prophet Muhammad (PBUH)established peaceful relations with Jewish and non-Muslim Arab tribes. These interactions had a profound influence on the development of Islamic jurisprudence and interfaith dialogue.
- The Treaty of Hudaybiyyah: After the Hijra, Holy Prophet Muhammad (PBUH) attempted to perform the pilgrimage to Mecca but was prevented. Instead, a truce known as the Treaty of Hudaybiyyah was established with the Meccans, allowing Muslims to return to Mecca for the pilgrimage in subsequent years.
- The Conquest of Mecca: In 630 AD, after several years in Medina, Holy Prophet Muhammad (PBUH) and his followers peacefully reconquered Mecca. This event marked the triumph of Islam in the Arabian Peninsula and the unification of the Arab tribes under the banner of Islam.
The Hijra was a turning point in Islamic history, as it led to the establishment of a thriving Muslim community in Medina and paved the way for the spread of Islam beyond the Arabian Peninsula. It remains a central and celebrated event in the Islamic calendar.

Scholars from various backgrounds gathered there, translating ancient texts into Arabic and advancing knowledge in fields like mathematics, astronomy, medicine, and philosophy.
- Influence on Islamic Art and Architecture: The Islamic conquests played a significant role in shaping Islamic art and architecture. Elements of Persian, Byzantine, and Central Asian styles were blended with Islamic aesthetics, resulting in unique and intricate designs, exemplified in the beauty of mosques, palaces, and calligraphy.

Battle of Tours, halting the Muslim expansion into Europe
The Battle of Tours, also known as the Battle of Poitiers, was a pivotal conflict that occurred in 732 AD, which is renowned for its role in halting the Muslim expansion into Europe. This significant event took place near Tours, in present-day France, when Frankish forces, led by Charles Martel, confronted the Umayyad Caliphate’s army, led by Abdul Rahman Al Ghafiqi.
The Umayyad Caliphate, which had been rapidly expanding its territory across North Africa and the Iberian Peninsula, sought to extend its conquests further into Europe. The clash at Tours marked a critical juncture in this expansion.
Charles Martel’s Frankish army employed a disciplined and heavily armored infantry, with a core of warriors known as the Carolingian Heavy Infantry. This Frankish force successfully withstood the Umayyad cavalry charges and mounted a counteroffensive, leading to a decisive victory.
The outcome of the Battle of Tours was profound, as it effectively halted the Umayyad advance into Europe. The Frankish victory is often considered a turning point in European history, as it helped preserve Western Christendom and prevent further Islamic expansion into Europe. While this battle did not entirely reverse the Muslim presence in the Iberian Peninsula, it significantly limited their northward expansion.
Charles Martel’s leadership and the valor of his troops in this battle have earned him the moniker “Martel,” which means “The Hammer” in French. The Battle of Tours holds a lasting place in the collective memory of Europe and stands as a symbol of resistance to foreign invasions. It remains a subject of historical debate and fascination due to its far-reaching consequences for the course of European history.
