Let’s go through these eras in more detail.

Early History of Islam During Prophet Muhammad’s (PBUH) Lifetime (610 CE–632 CE)

During the lifetime of Prophet Muhammad (PBUH), the early history of Islam began to unfold. He spent 13 years in Mecca calling people to Islam, facing denial, hostility, and harm. Despite the opposition, he remained patient and steadfast. In 7 AH (around 628 CE), Prophet Muhammad (PBUH) sent messengers to major world powers, including the Sassanian and Byzantine empires, establishing the first diplomatic ties between these empires and the emerging Muslim state.

Abu Bakr Era (632 CE–634 CE)

After the death of Prophet Muhammad (PBUH) in 11 AH/ 632 CE, Abu Bakr (RA) became the first Caliph of the Muslim community. He unified the Arab tribes of the Arabian Peninsula and led the Wars of Apostasy (Ridda Wars) from 632 to 633 CE to suppress internal revolts. Abu Bakr (RA) also launched the first military campaigns against the Byzantine and Sasanian empires, laying the foundation for future Islamic territorial expansion. Additionally, he ordered the compilation of the Quran to ensure the preservation of its teachings.

The Era of Umar ibn al-Khattab (634 CE–644 CE): A Key Period in the Early Expansion of Islam

After the death of Abu Bakr Al-Siddiq (RA), Umar ibn al-Khattab (RA) became the second Caliph of the Muslim community in 634 CE (13 AH). His leadership marked a significant period in the early history and expansion of Islam.

Under Umar’s command, the Muslim state expanded rapidly. Territories extended north into Iraq and Syria and west into Egypt. Major milestones during his caliphate include:

In 636 CE, Muslim forces defeated the Byzantine army at the Battle of Al-Yarmook and gained control of Palestine.
In the same year, initial expeditions toward India began.
In 637 CE, the Persian Empire collapsed after the Muslim victory at the Battle of Al-Qadisiyah.
Between 639–641 CE, Egypt came under Muslim rule.
By 641 CE, the Muslim empire encompassed the Arabian Peninsula, Palestine, Syria, and Egypt.
By 642 CE, Muslim control extended to the North African coast.
Islam officially entered Jerusalem in 15 AH (636 CE) during Umar’s caliphate.

When Caliph Umar arrived in Jerusalem, he entered the city with humility, respectfully engaged with local Christian leaders, guaranteed the safety of its citizens, and ensured freedom of worship—hallmarks of Islamic governance. He also prayed within the city, honoring its sacred sites.

Umar ibn al-Khattab’s leadership built upon the foundations laid by Abu Bakr (RA) and set the stage for the continued rapid spread of Islam. His name is also preserved on historical inscriptions at Mount Salʿ in Medina, alongside those of Prophet Muhammad (PBUH), Abu Bakr (RA), and ʿAli (RA).

The Umayyad Caliphate (661–750 CE): A Major Era in the Expansion of Islam

The Umayyad Caliphate, which ruled from 661 to 750 CE, marked a major period in the history and expansion of Islam following the era of the early Caliphs. Under the Umayyads—and later the Abbasids—the Islamic empire spread across vast regions of Afro-Eurasia, stretching from the Atlantic Ocean in the west to India in the east.

During these expansions, Muslims shared Islamic teachings while interacting with a wide range of cultures. Historical sources emphasize that these conquests were not aimed at forcing conversions to Islam. Instead, the goal was to establish safe, just societies where people could freely learn about Islam and convert willingly if they chose. Throughout the Islamic empire under Umayyad rule, many non-Muslims were allowed to practice their own religions peacefully.

Key events of expansion efforts during the Umayyad Caliphate include:

711 CE: Muslims entered Andalusia (Spain) during the reign of Umayyad Caliph Al-Walid ibn Abdul Malik. From this point, Andalusia became part of the Islamic world. Leaders like Al-Samh ibn Malik and Abdul Rahman Al-Ghafiqi governed and expanded Muslim rule beyond the Pyrenees Mountains into France.
712 CE: Muslim forces crossed the Mediterranean and solidified their presence in Spain.
665 CE (44 AH): Caliph Muawiya ibn Abi Sufyan initiated campaigns in India, sending Al-Muhallab ibn Abi Sufra to launch early invasions into the Sindh region.
711 CE (92 AH): Muhammad ibn Qasim led a successful campaign into Sindh (modern-day Pakistan) against Raja Dahir at the Battle of Debal, establishing Islamic rule in parts of northern India.
732 CE: The Battle of Tours (or Poitiers) took place during the Umayyad period, where the Muslim army under Abdul Rahman Al-Ghafiqi fought to expand into France. Although the battle halted further northward expansion into Europe, it remains a significant event in Islamic military history.

The Umayyad Caliphate played a vital role in transforming the Islamic community into a vast, interconnected empire, laying cultural, legal, and political foundations that influenced later Islamic civilizations.

The Abbasid Caliphate (750–1258 CE): The Golden Age of Islamic Civilization

The Abbasid Caliphate ruled from 750 to 1258 CE, succeeding the Umayyad Caliphate (661–750 CE). Under the leadership of the Umayyads and then the Abbasids, the Islamic empire expanded massively across Afro-Eurasia, stretching from the Atlantic Ocean to India.

Historical sources highlight that the conquests during this period were not intended to force people to embrace Islam. Instead, the aim was to establish safe and just societies where individuals could learn about Islam and convert willingly if they chose. Non-Muslims within the Abbasid Empire were often free to practice their religions peacefully.

The Abbasid era inaugurated what is famously known as the Golden Age of Islamic Civilization, centered in Baghdad. This period saw a flourishing of knowledge across various fields, laying the foundations for many aspects of modern civilization. Muslim scholars, scientists, merchants, and translators preserved the heritage of earlier civilizations—such as Greek philosophy—and pioneered new fields including algebra, biology, astronomy, mathematics, and medicine.

Key expansion and development efforts during the Abbasid Caliphate include:

Early Abbasid Caliphs like Al-Saffah (132–136 AH) and Al-Mansur (136–158 AH) maintained Islamic influence in India by dispatching military expeditions.
Under Caliph Al-Mansur, Amr ibn Muhammad ibn Qasim consolidated Muslim rule in Sindh and expanded into regions like Kashmir and Multan.
Subsequent caliphs, including Al-Hadi (158–169 AH) and Harun al-Rashid (170–193 AH), continued supporting campaigns in India, though not all expeditions succeeded.
Caliph Al-Ma’mun (198–218 AH) also pursued strategic efforts to maintain influence over India.

Despite remarkable achievements, the Abbasid Caliphate experienced political decline between 900 and 1258 CE. The vast size of the empire made it difficult to govern effectively, leading to internal conflicts, revolts, and betrayals. The decline culminated in 1258 when the Mongols invaded Baghdad, killed the last Abbasid Caliph, and destroyed the famed House of Wisdom.

Even after the political collapse, the cultural and religious influence of Islam continued. The concept of Dar al-Islam (“House of Islam”) expanded from 1200 to 1450 across Afro-Eurasia. Between 1000 and 1500, the size of Dar al-Islam nearly doubled, reaching new regions such as Sub-Saharan Africa, the East African coast, India, and the islands of Southeast Asia.
This period (1200–1450) is viewed as a cultural and religious extension of Islam’s Golden Age.

Here’s the summary table of the key events during the Abbasid Caliphate (750–1258 CE):

1200–1450 CE	Dar al-Islam continues to expand across Afro-Eurasia, reaching Sub-Saharan Africa, Southeast Asia, and India.

Key Events of the Ottoman Empire (1299-1924)

The history of the Ottoman Empire spans over six centuries and is marked by powerful rulers and transformative events that shaped its rise, golden age, and eventual decline. Below is a chronological overview of the most important sultans and key historical moments:

Ertuğrul (Before 1281) – Father of Osman I who settled in Söğüt under the Seljuk Sultanate, laying the foundation for the future Ottoman state.
Osman I (1281–1326) – Founder of the Ottoman Empire; initiated territorial expansion and established the foundations of a state built on jihad and justice.
Murad II (1421–1451) – Rebuilt the empire’s power and stability in both Anatolia and Europe, paving the way for future conquests.
Mohammad II – “The Opener” (1451–1481):
In 1453, Mehmed II achieved one of the most significant events in world history: the Conquest of Constantinople. This monumental victory transformed the Ottoman state into a powerful empire and dramatically raised its ambitions. The conquest instilled confidence among both leaders and citizens, shifting the Ottomans from a regional power to a global force.
Following the conquest, the empire expanded its military capabilities, focusing on naval strength and increasing the size of its armies. By controlling key straits, such as the Bosporus and Dardanelles, the Ottomans gained economic advantages through customs duties on trade routes passing through these waterways.
Historian Donald Pitcher notes that Ottoman control over the straits led to significant economic growth, enabling the state to pursue broader territorial ambitions, including control over Black Sea ports. More importantly, this victory marked the beginning of the Ottomans’ transformation into a global empire with major administrative and ideological changes that reshaped the state’s governance.
Selim I – “The Grim” (1512–1520) – Expanded the empire into the Middle East by defeating the Safavids and Mamluks, bringing the holy cities of Mecca and Medina under Ottoman control.
Suleiman the Magnificent (1520–1566) – Led the empire during its golden age, expanding further into Europe, reforming legal systems, and fostering advancements in architecture, science, and the arts.
Murad IV (1623–1640) – Restored central authority during a period of decline and led successful campaigns against Persia.
Mohammad IV (1648–1687) – Oversaw both military successes, such as the Siege of Vienna, and the beginning of the empire’s decline due to internal instability.
Selim III (1789–1807) – Initiated major military and administrative reforms (Nizam-i Cedid) to modernize the empire amid rising European powers.
Abdulhamid II (1876–1909) – Known for resisting European pressures and famously rejecting Zionist settlement in Palestine despite the empire’s declining power.
Mohammad VI (1918–1922) – The last Ottoman Sultan; his reign ended with the abolition of the sultanate and the eventual collapse of the empire.
(1924): The official end of the Ottoman caliphate. Since then, there has been no official and unified political or religious leadership for Muslims worldwide.

Following is a table including Ottomon era key events, arranged chronologically:

Mohammad VI	1918–1922	The final Ottoman Sultan; deposed following the empire’s dissolution and the abolition of the Sultanate.
Abolition of the Caliphate	1924	The official end of the Ottoman Caliphate. Since then, Muslims have had no unified political or religious leadership.

After the Caliphate: How Islam Continues to Spread Rapidly

Despite the official abolition of the Ottoman Caliphate in 1924, Islam has continued to grow at a remarkable pace across the globe. Far from fading, the faith has expanded well beyond its early political structures, driven by its spiritual appeal, global migration, higher birth rates, and increasing conversions.

Islam has long been recognized as one of the fastest-growing religions in the world. A striking example of this growth is reflected in global population statistics. For instance, estimates had projected that the Muslim population would reach around 1.5 billion by the year 2020. However, actual figures far exceeded expectations, reaching 1.8 billion—300 million more than predicted.

By 2024, the Muslim population has crossed the 2 billion mark, accounting for approximately 25.8% of the global population. The map below (if applicable) illustrates the distribution of Muslims around the world as of 2024, showcasing Islam’s widespread presence across continents.

This extraordinary growth traces back to a single individual: Prophet Muhammad, peace and blessings be upon him. From a solitary voice in the Arabian Peninsula, his message now resonates with over 2 billion followers globally—an unprecedented expansion in religious history.

Islam’s rise is not just historical but ongoing. Even without a centralized caliphate or a unified political structure, the Islamic faith continues to inspire, attract, and guide millions every year across diverse cultures and regions.

Conclusion:

The Islamic timeline spans over 14 centuries, beginning with Prophet Muhammad ﷺ and continuing through the era of the Rightly Guided Caliphs, the expansion under major empires like the Umayyads, Abbasids, and Ottomans, and into the post-caliphate modern era. Each chapter has played a critical role in shaping Islamic civilization and its influence on the world. Despite political upheavals, the core message of Islam has endured, with the Muslim population continuing to grow and spread globally. This timeline not only chronicles key historical milestones but also reflects the dynamic and enduring nature of Islam from its inception to its present-day global significance.
