Arab Conquest of Sindh and the Ghaznavids

1. Who led it, and why him

The conquest was an Umayyad enterprise. Al-Hajjaj ibn Yusuf, the governor of Iraq, ran it during the reign of Caliph al-Walid I. He chose a very young man to lead it. Muhammad ibn al-Qasim was his kinsman. The Chach Nama calls him Hajjaj’s nephew and son-in-law, and says he was “a youth of seventeen”.

Hajjaj then gave him real strength. Baladhuri says he reinforced Qasim with 6,000 Syrian troops. He also supplied everything Qasim wanted, “even to thread and needles”.

2. What triggered the invasion

The Arab chroniclers give a pirate story. A ship carrying women born in Ceylon, sent to Hajjaj, was seized by pirates (the *bawarij*) near Debal. Hajjaj wrote to Dahir, the ruler of Sindh, and asked him to free them. Dahir replied that pirates he could not control had taken them. Hajjaj sent two expeditions against Debal. Both failed, and both commanders were killed. Qasim was the third try.

Treat this as the Arab account of the cause. It does not stand alone. Baladhuri also lists earlier Arab raids on this frontier, going back to the days of Mu’awiya. Sindh was already a target before the pirate story.

3. The campaign, step by step

Qasim marched overland through Makran. Ships met him at Debal with men, weapons and supplies. He took the port by siege. Then he moved north, made treaties with several towns, and crossed the Indus on a bridge he built. The decisive fight is known as the Battle of Aror, near Rawar. Dahir fought on, was forced off his elephant, and was killed near evening. The battle is dated to 20 June 712.

After that, Qasim took Brahmanabad. He then crossed the Beas and besieged Multan. Many towns surrendered by treaty, and Baladhuri says he imposed the *kharaj* (land tax) on them.

4. Baladhuri: the sober chronicle

Al-Baladhuri was a 9th-century Muslim historian who worked in Baghdad. He died in 892 or 893. His *Futuh al-Buldan* (“Conquests of the Lands”) was written more than a century and a half after the events. It reads like a ledger. It lists governors, raids, sieges and treaties, and it names who told him each report.

Historians prize it for bare facts. It gives few speeches and little drama.

5. The Chach Nama: the long story

The Chach Nama is far fuller. It has speeches, letters, treachery and a tragic hero. But it survives only as a Persian text. It says it is a translation by `Ali Kufi, from an older Arabic original. The English edition’s note places Kufi in the early 13th century, around 1216 CE. That is roughly 500 years after the conquest.

That gap matters. It is the main source for most of the dramatic detail people remember, such as Qasim’s age.

6. How historians now read the Chach Nama

Manan Ahmed Asif has argued that the Chach Nama is not a translation of an 8th-century record. In his view it is an original 13th-century work. It was shaped by the politics of its own time, and it is closer to a romance than to a chronicle.

Other scholars also question the reliability of some of its reports. So the safe habit is simple. Use Baladhuri for what happened. Use the Chach Nama for how later writers wanted to tell the story, and flag its details as unconfirmed.

7. The Arab push beyond Sindh

After Sindh, Arab governors tried to push east into Rajasthan and Gujarat. Raids in the 720s and 730s reached Malwa and Gujarat, and some places were sacked. In 738–39 a Chalukya force under Avanijanashraya Pulakeshin defeated the Arabs near Navsari. His own inscription of 738–739 records the victory.

In short, Umayyad expansion stayed restricted to Sindh. The Arabs never built a province in Rajasthan or Gujarat.

8. Nagabhata I and the unsure place

Many accounts credit the Pratihara king Nagabhata I with repelling an Arab force, and they often place it at Ujjain. The evidence is thinner than the story. A later inscription of Bhoja I says Nagabhata defeated a large army of “Mlecchas”. It does not name the place.

So the safe wording is that Nagabhata I is credited with repelling an Arab force. Where he did it is not firmly known.

9. Sindh slips out of direct rule

Direct caliphal rule of Sindh did not last forever. In 854 ‘Umar ibn ‘Abd al-‘Aziz al-Habbari began the Habbari line. By 861 Sindh was semi-independent. The Habbaris still gave nominal allegiance to the Abbasid caliph in Baghdad.

They ruled central and southern Sindh from Mansura. This was the Arab-descended emirate that Mahmud of Ghazni found there.

10. Mahmud of Ghazni closes the loop

Mahmud was Turkic, not Arab. His father Sabuktigin was a Karluk Turkic slave who founded the Ghaznavid line at Ghazni. Mahmud attacked India seventeen times and used the plunder to build up Ghazni.

His most famous raid hit Somnath in 1025–26. In 1026 he also sacked Mansura. He defeated the Habbaris, annexed Sindh to the Ghaznavid empire, and so ended Arab rule there.

11. The two waves side by side

The two waves differ in more than date. Qasim was an Arab general of the Umayyad Caliphate, and he came overland through Makran, with ships bringing supplies. Mahmud was a Turkic sultan who ruled from Ghazni. He came overland from the northwest and struck India again and again.

A common slip is to say Qasim came “by sea”. The ships carried men and supplies to Debal. The army marched.

12. Why these two waves share an article

They are grouped because both came before permanent Muslim rule in India. They were not connected campaigns. The first built a province on the Indus. The second took wealth from the north and the west and returned it to Ghazni.

The same line separates both from what came next. The Ghurid conquest stayed and built the Delhi Sultanate.
