The Fath al-Makkah, or the Conquest of Mecca, occurred on 20th Ramadan, in the year 8 AH (Hijri calendar), which corresponds to January 630 CE in the Gregorian calendar.

Fath al-Makkah, also known as the Conquest of Mecca, was a pivotal event in the early history of Islam. It occurred in the year 630 CE when the Prophet Muhammad and his followers conquered the city of Mecca, which had previously been hostile to the Muslim community.

The term "Fath" means "victory" or "conquest," while "Makkah" refers to the city of Mecca, the holiest site in Islam and the birthplace of the Prophet Muhammad. The conquest of Mecca was a significant turning point in the early history of Islam, as it marked the end of the hostilities between the Muslim community and the people of Mecca who had previously persecuted and opposed them.

The conquest of Mecca is considered a peaceful victory, as the Prophet Muhammad showed great mercy and forgiveness towards the people of Mecca upon its capture. He entered the city with an army of ten thousand Muslims and forgave those who had previously opposed him, thus demonstrating the principles of compassion and forgiveness that are central to Islamic teachings.

The Fath al-Makkah was a momentous occasion in the history of Islam, as it marked the beginning of the consolidation of Muslim power in Arabia and the eventual spread of Islam to other parts of the world. Today, Muslims commemorate this event during the annual pilgrimage to Mecca, known as the Hajj, as a reminder of the importance of peace, forgiveness, and unity in the Islamic faith.
