Pakistan Studies — Chapter 13, Part 1

Early History & Muslim Rule in India — From the Indus Valley to the Ghoris

Why this chapter matters: this is the longest runway in Pakistan Studies — from 2500 BC to 1192 AD — and paper-setters mine it in two ways: the ancient one-liners (sites, books, kings) and the conquest chain (Qasim → Ghaznavi → Ghori → Delhi Sultanate). Our verified banks hold 222 questions matching this whole topic, and the single heaviest block inside it is the Mughals (97 in Part 2). Learn the chain in order and the dates stop floating: every conqueror, dynasty and battle hangs on the one before it.

Exam Trend — OPC ancient fold-in (Section 7A, added 2026-11-02): 🔁 most repeated — Gandhara art and Taxila (17 bank rows across 16 files, 2002–2025 papers). ⭐ must-know — the same Gandhara/Taxila pair: still asked in a 2025 PPSC paper (Junior Clerk, Gandhara art famous for statue-making). No 🆕 mark is claimed for this block — none of its items is a 2025–26 first appearance; the other Section 7A rows are taught without marks (below both 🔁 limbs).

1. The Indus Valley Civilization

• 4500 years ago = 2500 BC — the date papers ask.
• Mohenjo-daro = Mound of the Dead, near Larkana.
• Harappa, near Sahiwal.
• Both stood on the Indus River system; Harappa on the east side, the Indus Valley sites on the west.
• Two theories of decline are taught: flood and Aryan invasion.

2. Aryans, books, gods and castes

• The Aryans came from Central Asia (about 2000 BC) and reached the subcontinent by 1500 BC, settling in Punjab.
• The four Vedas: Rig Veda (the oldest), Sama Veda, Yajur Veda, Atharva Veda.
• Holy books to keep apart: Upanishads = Hindu; Guru Granth = Sikh; Tripitaka = Buddhist.
• The Hindu trinity: Brahma = creator, Vishnu = preserver, Shiva = destroyer.
• The caste system: Brahmin (priests), Kshatriya (warriors), Vaishya (businessmen), Shudra (labourers).

3. Persia, Alexander and the ancient kingdoms

Persia

• Persia = the old name of Iran (فارس). Its religion, Zoroastrianism, is the religion of the Parsis (fire worshippers).

Alexander the Great

• Son of Philip; became king of Macedonia at 20; married the Persian noblewoman Roxana.
• Alexander vs Darius III: 333 BC. Taxila’s old name was Takshashila.
• Porus answered Alexander “like a king” — and Alexander made him a friend.
• He entered North India in 327 BC and reached Multan in 326 BC, where the Malhi tribe held a walled city and a poisoned arrow wounded him.
• He returned partly by ships and partly through the Makran desert, where half his army died.
• He died in 323 BC — king 336–323 BC, 13 years, aged 33. Three generals divided the empire; one was Seleucus.

Magadha, Mauryas, Greeks, Kushans, Guptas

• Magadha Empire: 700 BC; Chandragupta Maurya with his minister Chanakya. The Nanda Empire and the Wall of Rajgir (40 km, 6th century BC) belong here.
• Mauryan Empire: Chandragupta Maurya (326 BC); he later became Jain.
• Ashoka (269–232 BC): after the War of Kalinga (100,000 killed, 150,000 homeless) he embraced Buddhism at state level.
• Bactrian Greeks: 175 BC; King Menander (Milinda); the book “Questions of Milinda”.
• Scythians: 60–50 BC; then the Parthians.
• Kushans: 50–250 AD; Kanishka (120–150 AD) convened a Buddhist conference that split Buddhism into Mahayana (Buddha as god) and Hinayana (Buddha as human).
• The Sassanid Empire ruled Persia; the Gupta Dynasty (its Chandragupta) came some 600 years after the Mauryan Chandragupta, as taught; the Huns arrived in 480 AD; Harsha’s golden period began in 606 AD.
• Pala Dynasty of Bengal (8th century CE): founded by Gopala — the Bengal dynasty the ancient-kingdoms sequence had not named (PMS Screening 2026 GK Final Mock Test, Q82; mock-only bank row, no mark claimed).

4. Master table — the ancient spine

5. Muhammad bin Qasim and the conquest of Sindh (712)

The Umayyad frame (only what the conquest needs)

• Umayyad Caliphate: 661–750 AD, 14 caliphs. First: Muawiya bin Abu Sufyan (661–680); Yazid bin Muawiya (680–683) — Karbala (61 Hijri) fell in his era; Muawiya bin Yazid ruled only 40 days; Abdul Malik bin Marwan (685–705) sent Hajjaj bin Yusuf; Walid bin Abdul Malik (705–715) sent Muhammad bin Qasim; Umar bin Abdul Aziz (717–720 = 99–101 Hijri) was called Umar Sani and Mujaddid, and government-level hadith compilation started in his era; the last caliph, Marwan Sani, fell at the Battle of Zab (750) to the Abbasids.
• Dots on the Quran (nuqat) are credited to Abdul Malik; a’rab to Hajjaj bin Yusuf.

Sindh before the conquest

• The Rai Dynasty gave way when Chach, the wazir, married the last Rai ruler’s widow and founded the Brahmin dynasty. Chachnama is the history of Sindh.
• Raja Dahir was king when Muhammad bin Qasim came. His wazir was Sisakar, his queen Rani Ladee Bai, his capital Alor/Aror. The rulers were Brahmins (Hindus); the subjects were Buddhists, unhappy with the dynasty — though Dahir’s army was strong.

Why the invasion happened

• Serandip is the old name of Sri Lanka. Its governor sent 8 ships: one with gifts and jewels for the caliph, one with the dead bodies of Arab traders plus their widows and orphans, six with goods and people.
• A sea storm near Sindh drove all 8 ships, tied together with ropes, to Debal. Nahid of the Yajbu tribe wrote to Hajjaj that sea pirates — the Med tribe — had seized them.
• Hajjaj demanded the ships back from Raja Dahir; Dahir replied the pirates were not under him. Hajjaj first sent Ubaidullah with 1,000 soldiers and 300 horses — all were martyred.

The conquest

• Muhammad bin Qasim: 712 AD (93 Hijri), in Sindh. Age 17; born 695 AD, died 715 AD (aged 20); title Imaduddin; tribe Saqfi. Sent by Hajjaj bin Yusuf, governor of Iraq/Basra — Hajjaj’s nephew and son-in-law. He came in Walid’s era and was recalled by Sulayman bin Abdul Malik; Hajjaj died 714, Muhammad bin Qasim died 715.
• Earlier attempts: in Umar’s era, Usman bin Abi al-Aas, governor of Bahrain, attacked Thana and Bharuch; Muhallab bin Sufra raided in 644 AD; in Usman’s era, interest in Makran failed — large armies died of hunger and thirst in the desert, small forces were killed by pirates and robbers.
• He came with 6,000 men; more joined on the way, making 10,000–12,000.
• The people’s superstition: a red flag stood and they believed no one could defeat them while it stood. Muhammad bin Qasim knocked it down with a manjaniq (catapult) and their morale broke.
• He defeated and killed Dahir at Alor/Aror, then took Brahmanabad (ruled by Dahir’s brother) and Multan, and was heading toward Kashmir when Walid died in 715 and Sulayman recalled him.
• Rule of thumb: Islam came to Kashmir, Multan and Sindh through Muhammad bin Qasim.

Walid’s four commanders

Walid bin Abdul Malik’s world project had four commanders:

1. Muhammad bin Qasim → the subcontinent (712).
2. Musa bin Nusair → North Africa — the Berber tribe lives in North Africa. MATLE: Morocco, Algeria, Tunisia, Libya, Egypt — all Muslim through him. He was the first Muslim governor of Spain.
3. Tariq bin Ziyad → Gibraltar (Jabal al-Tariq) — he burned his boats after landing and conquered Spain in 711 AD.
4. Qutaiba bin Muslim → Central Asia (Tajikistan, Kyrgyzstan, Turkmenistan, Uzbekistan, Kazakhstan).

• In 715, Sulayman recalled all of them. Muhammad bin Qasim obeyed and returned; Musa returned; Qutaiba refused → martyred in Central Asia in 715. Muhammad bin Qasim was killed (sealed in a bag); Musa was heavily fined and made to beg.
• After 715, governors ruled under the caliph until 871, when the governor of Mansura declared independence. Raja Jaipal’s era begins about 992.

6. Mahmud of Ghazni and the Ghaznavids

• Sabuktigin was a slave of Alaptagin, from Ghazna, Afghanistan — the Sabuktigin of the deer (hirni) story in the school Urdu book: he freed the fawn after seeing tears in its mother’s eyes.
• Raja Jaipal, Raja of Lahore (his territory reached Peshawar), attacked Ghazna and was defeated; he promised a ransom, then refused it at home; attacked again and was defeated up to Peshawar; a third time he attacked while Sabuktigin was away — and faced Mahmud Ghaznavi, Sabuktigin’s son.
• Mahmud Ghaznavi: 17 attacks on the subcontinent; the first in 1001 AD (if the options give round figures like 900/950/1000/1100, use 1000).
• After defeat, Raja Jaipal committed suicide by setting himself on fire.
• Rule of thumb: Islam came to KPK and Balochistan through Mahmud Ghaznavi; to Punjab and Sindh through Muhammad bin Qasim.
• Somnath (Gujarat), 1026 AD: Shiva’s idol; 6.5 tons of gold taken; the idol floated in the air; Mahmud said he would be called an idol-breaker (but-shikan), not an idol-seller. Somnath’s temple doors were taken to Ghazna; the British brought them back in the 19th century — today installed in the Red Fort, Delhi.
• Multan was ruled by the Ismailis; Abu al-Fath Daud Qarmati sat there — Mahmud defeated him too.
• Mahmud’s title: Yaminuddaula. His slave Ayaz was made governor of Lahore (“in one row stood Mahmud and Ayaz”).
• Mahmud died 1030 AD; son Masud, then Bahram; 1030–1186 produced no big ruler.

Scholars of Mahmud’s era

• Al-Biruni (Abu Raihan al-Biruni) — lived in Mahmud’s era; wrote Kitab-ul-Hind. He measured the Earth’s radius as 6,378 (today’s figure about 6,340/38 — only 40 km difference), sitting at Nandana fort in Jhelum.
• Data Ganj Bakhsh — real name Ali bin Usman, also called Data Ali Hajveri; book Kashf-ul-Mahjoob; born 1009, lived 63 years, died 1072.
• Firdousi — wrote the Shah Nama; Mahmud promised a gold coin per verse but sent silver — Firdousi refused; the gold arrived after his death. The Shah Nama is the longest epic poem written by a single poet.

7. Muhammad Ghori and the road to Delhi

• Ghor is a region of Afghanistan; from it came Ghiyasuddin Ghori and his brother Shihabuddin Ghori. Ghiyasuddin stayed in Afghanistan; Shihabuddin came to the subcontinent and left Qutbuddin Aibak as his naib (governor) in Lahore.
• First Battle of Tarain, 1191 (about 40 km before Delhi): Prithvi Raj Chauhan won; his brother Khande Rao wounded Ghori; Aibak carried Ghori from the battlefield. Ghori vowed not to change his clothes or enjoy any luxury till he defeated Prithvi.
• Second Battle of Tarain, 1192: Ghori won.
• Ghori’s death near Jhelum — two stories are told (pneumonia vs killed by the Khokhars); the Khokhar story is the reliable one (the FPSC 2024 paper’s correct option). His mazar is at Sohawa, Jhelum — Dr Abdul Qadeer Khan built the shrine with his own money.
• Ghori’s four famous slaves: Qutbuddin Aibak (Lahore/Delhi), Nasiruddin Qabacha (Multan/Sindh), Tajuddin Yaldauz (Ghazni), Bakhtiyar Khilji (Bengal). Nasiruddin Qabacha is not Nasiruddin Mahmud — two different people.
• Pakistan’s Ghauri missile vs India’s Prithvi missile are named after the two sides of the Battle of Tarain.

7A. Pakistan Affairs OPC fold-in — the ancient block (OPC pp. 1–3)

New material from the One Paper Cracker Pakistan Affairs short notes (updated 10.03.2026), checked row by row against this chapter and the verified banks. Rows already taught above are not repeated; held rows are listed in the run log, not taught.

The Indus Valley, in closer detail

• Bronze Age civilisation; its most important feature is its advanced drainage system — well-planned cities with covered drains.
• Mother Goddess worship is the religious belief papers attach to it; its script is still undeciphered.
• Dancing Girl statue — Mohenjo-daro; the bull animal statue — Harappa. These two find-spots are the pair papers ask.
• The chapter’s 2500 BC date stands as the paper date for the civilisation (see the run log on OPC’s wider 3300–1300 BC radiocarbon span, not adopted as a replacement).

Mehrgarh — before Harappa

• Mehrgarh, on the Bolan River (Balochistan, Kacchi Plain), is one of the earliest farming settlements in South Asia and a pre-Harappan culture — the site papers name when they ask for the farming settlement that precedes the Indus Valley cities.
• Bank evidence: genuine Mehrgarh stems in FPSC 2004 and 2008 (Bolan River bank) and PPSC 2024 (Bolan Pass, Kacchi Plain) — below the 🔁 threshold, so no mark is claimed.

Gandhara 🔁 ⭐

• Gandhara Civilization — religion: Buddhism; cultural centre: Taxila, called the “Pearl of Gandhara”. Its art is Buddhist sculpture — Gandhara art was famous for statue-making, and Gandhara art is related to Taxila.
• Location: between the Indus River and the Kabul River (not Indus–Jhelum — see Traps).
• Taxila is also the subcontinent’s ancient learning centre — the oldest university of the subcontinent in OPC’s phrasing, and the city whose old name, Takshashila, is already taught in Section 3.

The king lists the chapter had not named

• Chanakya → Arthashastra: Chandragupta Maurya’s adviser and author of the Arthashastra (the treatise on statecraft). The chapter taught Chanakya as minister; the book title is the asked pair.
• Last Mauryan ruler: Brihadratha — the dynasty ends with him (assassinated by his general Pushyamitra Shunga, who founded the Shunga dynasty).
• Gupta Empire — founder (imperial line): Chandragupta I; the Gupta age is the Golden Age of ancient India. The chapter had named only a later Gupta Chandragupta, centuries after the Mauryan one — Chandragupta I is the founder answer the banks give.
• Harshavardhana is traditionally associated with popularising the Kumbh Mela — taught in that traditional phrasing, as the bank item words it, not as a dated foundation event. The chapter’s Harsha golden period (606 AD) is the same king.
• Aryans’ entry route: the Khyber Pass — the historic invasion route already taught in the Geography chapter’s passes table, now tied to the Vedic entry here.

Two book/author pairs from the conquest blocks

• “Muhammad bin Qasim” — Naseem Hijazi: the historical novel on the 712 conquest, asked in the PPSC 2019 paper (2 bank rows, same paper — no mark claimed). It sits with Section 5’s conquest, not as a history source.
• Mahmud of Ghazni attacked the Shahi Dynasty in the early part of his reign — the dynasty name behind Section 6’s Raja Jaipal battles (Jaipal was the Shahi ruler of Lahore/Peshawar). One genuine bank row; no mark claimed.

8. Rapid-fire one-liners (Part 1)

• Indus Valley: 2500 BC; Mohenjo-daro = Mound of the Dead, Larkana; Harappa = Sahiwal.
• Aryans: Central Asia → 1500 BC → Punjab.
• Vedas: Rig (oldest), Sama, Yajur, Atharva; Upanishads = Hindu, Guru Granth = Sikh, Tripitaka = Buddhist.
• Trinity: Brahma creator, Vishnu preserver, Shiva destroyer; castes: Brahmin, Kshatriya, Vaishya, Shudra.
• Alexander: 327 BC North India, 326 BC Multan, died 323 BC aged 33; Porus: “like a king”; Taxila = Takshashila.
• Ashoka: 269–232 BC; Kalinga: 100,000 killed, 150,000 homeless → Buddhism.
• Kanishka: 120–150 AD; Buddhist conference → Mahayana / Hinayana.
• Muhammad bin Qasim: 712 AD, 93 Hijri, Sindh, aged 17, Imaduddin, Saqfi, sent by Hajjaj, recalled by Sulayman.
• Dahir: wazir Sisakar, queen Rani Ladee Bai, capital Alor/Aror; the flag fell to a manjaniq.
• Walid’s four: bin Qasim (subcontinent), Musa bin Nusair (North Africa), Tariq bin Ziyad (Spain 711), Qutaiba bin Muslim (Central Asia).
• MATLE = Morocco, Algeria, Tunisia, Libya, Egypt.
• Mahmud: 17 attacks, first 1001, Somnath 1026, 6.5 tons of gold, but-shikan, died 1030, Yaminuddaula.
• Al-Biruni: Kitab-ul-Hind, radius 6,378, Nandana fort, Jhelum; Data Ganj Bakhsh: Ali bin Usman, Kashf-ul-Mahjoob, 1009–1072; Firdousi: Shah Nama.
• Tarain: 1191 Prithvi Raj Chauhan won; 1192 Ghori won; Ghori killed by the Khokhars; mazar Sohawa, Jhelum.
• OPC fold-in (Section 7A): Mehrgarh = Bolan River, pre-Harappan farming settlement; Gandhara = Buddhism, Taxila, between Indus and Kabul, statue-making art 🔁 ⭐; Chanakya = Arthashastra; last Mauryan = Brihadratha; Gupta founder = Chandragupta I, Golden Age; “Muhammad bin Qasim” = Naseem Hijazi; Mahmud attacked the Shahi dynasty.

9. Most-asked facts (from our verified past-paper banks)

• The 712 / Sindh / 17-year-old bin Qasim cluster and the Walid → Sulayman recall pair.
• Somnath 1026 and the but-shikan line; 17 attacks, first 1001.
• Tarain 1191 vs 1192 — who won each is the trap.
• Mohenjo-daro = Mound of the Dead, Larkana and Harappa = Sahiwal.
• Ashoka’s Kalinga figures and Kanishka’s Mahayana/Hinayana split.
• Al-Biruni’s Kitab-ul-Hind and Data Ganj Bakhsh’s Kashf-ul-Mahjoob — author–book pairs are asked as a set.

10. Traps & confusions (Part 1)

• Nasiruddin Qabacha ≠ Nasiruddin Mahmud — Qabacha was Ghori’s slave (Multan/Sindh); Mahmud was the Slave-dynasty sultan of Part 2.
• First Tarain (1191) vs Second Tarain (1192): Prithvi won the first, Ghori the second. Papers swap them.
• Mahmud’s first attack 1001 vs the round-option 1000: use 1001 unless the options are all round figures — then 1000.
• Islam’s routes: Kashmir/Multan/Sindh via bin Qasim; KPK/Balochistan via Mahmud — not the other way round.
• Two Chandraguptas: Chandragupta Maurya (Magadha/Mauryan) vs the later Gupta Chandragupta — centuries apart.
• Two Dariuses in the telling: the Persian king Alexander faced was Darius III; the lecture’s reign-range figure for Darius is not used here.
• Serandip = Sri Lanka (old name), Debal = where the storm drove the ships — not where they were sent from.
• Gandhara’s rivers: Indus and Kabul — one bank item pairs it with Indus–Jhelum; that pairing is not the Gandhara heartland (the Peshawar valley between Indus and Kabul) and is not taught.
• Two Chandraguptas, now three names to keep apart: Chandragupta Maurya (founder, with Chanakya) vs Chandragupta I (Gupta founder, Golden Age) vs the later Gupta Chandragupta of Section 3 — the founder question’s answer is Chandragupta I, not the Mauryan.
• Sisakar/Siskar is one person, two spellings: Section 5 teaches him as Dahir’s wazir; OPC calls him Dahir’s commander. The name is the asked fact; the title varies by source.

11. Memory tricks (from the lectures)

• MATLE for Musa bin Nusair’s North Africa: Morocco, Algeria, Tunisia, Libya, Egypt.
• The conquest chain: Qasim (712) → Ghaznavi (1001) → Ghori (1192) — roughly three centuries apart, each opening the next door: Sindh, then the north-west, then Delhi.
• Tarain’s pair: 1191 = Prithvi’s year, 1192 = Ghori’s year — the winner changes when the last digit changes.
• Somnath’s 6.5: the gold figure ends in .5, like a half — 6.5 tons, 1026.
• Al-Biruni’s 40 km: his radius (6,378) missed today’s figure by only 40 km — a medieval measurement that close is itself the memory hook.
• Gandhara’s pearl: Taxila is the pearl — a pearl sits in a river valley, and Gandhara sits between two rivers (Indus, Kabul).
• Mehrgarh before Harappa: Mehrgarh = Mother of Harappa’s farming — Bolan River, before the cities.

12. Visuals (site build specs)

• MAP — The ancient sites and the invasion routes: Indus sites (Mohenjo-daro near Larkana, Harappa near Sahiwal), Taxila, Multan, Debal, Ghazna, Somnath and Tarain, with three coloured arrows for bin Qasim (712), Mahmud (1001–1026) and Ghori (1191–1192) — placed after Section 4.
• TIMELINE — 2500 BC → 1192 AD: horizontal band from the Indus Valley through Alexander, Ashoka, Kanishka, bin Qasim, Mahmud and Ghori — placed before Section 1 as the part’s orientation graphic.
• DIAGRAM — Walid’s four commanders: four panels (bin Qasim, Musa bin Nusair, Tariq bin Ziyad, Qutaiba bin Muslim) with destination and year — placed in Section 5.
• MAP — The ancient block (Section 7A): Mehrgarh (Bolan River) → Indus cities → Taxila/Gandhara (Indus–Kabul) in one west-to-east strip — placed in Section 7A.

13. Practice this topic

• Practice set: 222 verified past-paper questions in the PPSC + FPSC banks match this topic’s sub-topics by tight question-text keyword, first-match (ancient 28, bin Qasim/Ghaznavids/Ghoris 18, Delhi Sultanate 23, Mughals I 97, later Mughals & East India Company 56) — the site serves them as this chapter’s practice set, with the IBES Pakistan Studies capsule questions behind them. Note: a question is counted once, under its first matching block, so battle names shared across eras (e.g. Panipat) sit in the earlier block.
