Conquest of Mecca: Muhammad and his followers conquer the city, and the Quraysh association of clans surrenders.

The conquest of Mecca was a military campaign undertaken by Muhammad and his companions during the Muslim–Quraysh War. They led the early Muslims in an advance on the Quraysh-controlled city of Mecca in December 629 or January 630. The fall of the city to Muhammad formally marked the end of the conflict between his followers and the Quraysh tribal confederation.

Muhammad was an Arab religious, military and political leader and the founder of Islam. According to Islam, he was a prophet who was divinely inspired to preach and confirm the monotheistic teachings of Adam, Noah, Abraham, Moses, Jesus, and other prophets. He is believed by Muslims to be the Seal of the Prophets, and along with the Quran, his teachings and normative examples form the basis for Islamic religious belief.

The Quraysh were an Arab tribe who controlled Mecca before the rise of Islam. Their members were divided into ten main clans, most notably including the Banu Hashim, into which Islam's founding prophet Muhammad was born. By the seventh century, they had become wealthy merchants, dominating trade between the Indian Ocean, East Africa, and the Mediterranean. The tribe ran caravans to Gaza and Damascus in summer and to Yemen in winter, while also mining and pursuing other enterprises on these routes.
