Explanation:
By 712 AD Islam had reached Asia. Arab traders used to sail along the Persian Gulf and along the Makran Coast. Near the port of Daibul in 710 an Arab ship was seized which was carrying cargo to Caliph Walid in Damascus.
Caliph Walid demanded Raja Dahir to return prisoners and teasures but he refused.
So he sent an army under the leadership of his nephew Mohammad Bin Qasim who was only 17 years old. Mohammad Bin Qasimand his army quickly captured Daibal and killed Raja Dahir in a battle. The Arabs then marched inland along the Indus Valley . With the surrender of Multan, Sehwan, Sindh and southern Punjab now became Arab Territory.
In 871 the territory became two independent Muslim States. Sindh continued as a part of the Arab empire for the next 200 years.
The Ghaznavids were Muslims whose empire stretched from central Asia to Afghanistan. Their king Subuktagin ( 977-97) made many raids into the subcontinent and later added the remaining part of Punjab to his Muslim empire.
His son also continued raids for next 30 years . His son allowed Non Muslims to follow their own religion.
The small state if Ghor was ruled by two brothers. One invaded central Asia and the other , Muhammad Ghori invaded India.
Ghori was murdered in 1206 and Qutbuddin Aibak was the first Muslim ruler of all northern India. He died in 1210 and his Illtutmish continued.
The Mongolians travelled across the great plains of central Asia with their animals. Their Leader Changez Khan attacked many times but after never winning went back to central Asia. When Changez khan died the Mongols becames Muslims.
