OR
How did the Indian Crafts persons lose their independence?

Weavers no longer had the liberty of selling their cloth or weaving their patterns. Instead, they had to reproduce the designs supplied to them by the company agents. This system snatched the freedom of the Indian weavers. They began to be guided by someone else.

Long Answer Type Questions

1. Describe the trade activities of the big and small traders belonging to the medieval time.

Answer: There were many kinds of traders. These included the Banjaras and several traders especially horse traders.
The traders usually travelled in caravans and formed guilds to protect their interests. There were several such guilds in South India from the eighth century onwards—the most famous being the Manigramam and Nanadesi. These guilds traded extensively both within the peninsula and with Southeast Asia and China. There were also communities like the Chettiyars and the Marwari Oswal who went on to become the major trading groups of the country.

Gujarati traders, including the communities of Hindu Baniyas and Muslim Bohras, traded extensively with the ports of the Red Sea, Persian Gulf, East Africa, Southeast Asia, and China. They sold textiles and spices in these ports and exchange, brought gold and ivory from Africa; and spices, tin, Chinese blue pottery, and silver from Southeast Asia and China.

The towns on the west coast were home to Arab, Persian, Chinese, Jewish, and Syrian Christian traders. Indian spices and cloth sold in the Red seaports were bought by Italian traders and eventually reached European markets, fetching high profits. This ultimately drew European traders to India.

2. Describe Swat as a gateway to the West           [V. Imp.]
Answer:  Surat in Gujarat was the emporium of western trade during the Mughal period along with Cambay (now Khambat) and somewhat later, Ahmedabad. Surat was the gateway for trade with West Asia via the Gulf of Ormuz. Surat has also been called the gate to Mecca because many pilgrim ships set sail from here.

Surat was a cosmopolitan city inhabited by people of all castes and creeds. In the 17th century the Portuguese, Dutch and English had their factories and warehouses at Surat. Several retail and wholesale shops could be found in Surat. These shops sold cotton textiles. Here, it is worth mentioning that the textiles of Surat were famous for their gold lace borders, le. zari and had a market in West Asia, African and Europe.

The state provided all the facilities to the people who came to the city from all over the world. The Kathiawad seths or mahqjaxvs had huge banking houses at Surat. The Surat hundis were honoured in far-off markets of Cairo in Egypt, Basra in Iraq and Antwerp in Belgium.

                                                           LONG ANSWER TYPE QUESTIONS

1 Compare the reasons why temples were built and destroyed?                             [V. Imp.]
Answer: Kings built temples to show their devotion to God and their power and wealth. King Rajarajeshvara built the Rajarajeshvara temple for the worship of his god, Rajarajeshvaram. Here, the names of the king and the god appear to be similar. The king took the god’s name because it was auspicious and he wanted to appear like a god. The largest temples were usually built by kings while the other, lesser deities in the temples were gods and goddesses of the allies and subordinates of the ruler.

The temple was a miniature model of the world ruled by the king and his allies. As they worshipped the deities together in the royal temples, it seemed as if they brought the just rule of the gods on earth. Kings built temples but when they attacked one another’s kingdoms they often targeted these buildings. In the early 9th century when the Pandyan King Shrimara Shrivallabha invaded Sri Lanka and defeated King Sena. he seized all the valuables such as the statue of the Buddha made entirely of gold and other golden images from various monasteries. King Sena II took revenge on this.

He invaded Madurai, the capital of the Pandyas in order to restore the gold statue of the Buddha. In the same way when in the early 11th century the Chola King Rajendra I built a Shiva temple in his capital. He filled it with prized statues seized from defeated rulers. Sultan Mahmud of Ghazni not only seized the valuables from the temples but . also destroyed them. He did it in order to win credit as a great hero of Islam Thus, rulers displayed their political might and military success by attacking and looting the places of worship of defeated rulers

  • It focused on a system of ethics—honesty, justice, peace. These values were universally applicable.

Long Answer Type Questions

1. Divide Akbar’s reign into three periods and give details about them.
Or
Mention the major campaigns and events of Akbar’s reign.
Answer:  Akbar’s reign can be divided into the following three periods.

  • 1556-1570. Akbar became independent of the regent Bairam Khan and other members of his domestic staff. He launched military campaigns against the Suris and other Afghans, against the neighbouring kingdoms of Malwa and Gondwana to suppress the revolt of his half brother Mirza Hakim and the Uzbeks. In the year 1568, he seized the Sisodiya Capital of Chittor and in 1569 Ranthambhor.
  • 1570-1585. Military campaigns in Gujarat were followed by campaigns in the east in Bihar, Bengal, and Orissa. These campaigns were complicated by the 1579-1580 revolt in support of Mirza Hakim.
  • 1585-1605. During this period Akbar expanded his empire. He launched campaigns in the north-west. Qandahar was seized from the Safavids and Kashmir was annexed. Kabul was seized after the death of Mirza Hakim. Afterward, Akbar started his campaigns in the Deccan and soon he annexed Berar, Khandesh, and parts of Ahmadnagar.

2. Write a short note on Akbar’s administrative policies.         [V. Imp.]
Answer:  Akbar’s administrative policies were mentioned in Abul Fazl’s book the Akbar Nama, particularly in its third and last volume, the Ain-i Akbari In the book Abul Fazl explained that the empire was divided into provinces known as Subas, governed by a Subadar. The Subadar carried out both political and military functions. Each province also had a financial officer or Diwan. For the maintenance of peace and order in his province, the Subadar was supported by several officers, for example

  • The military paymaster also is known as Bakhshi.
  • The minister in charge of religious and charitable patronage or
  • Military commanders called Faigdars, and
  • The town police commander called Akbar’s nobles commanded huge armies and had access to large amounts of revenue.

Akbar wanted to govern his empire peacefully. Hence he gave utmost importance to the idea of tolerance because it did not discriminate between people of different religions in his realm. He held religious discussions with the Ulama, Brahmanas, Jesuit priests who were Roman Catholics and Zoroastrians and came to the conclusion that the idea of sulh-i kul or ‘universal peace’ would work effectively. This idea focused on a system of ethics, honesty, justice and peace. These values were universally accepted.
Thus, Akbar’s administrative policies were based on considerate ideas,

3. Who were mansabdars? What were their responsibilities?
Answer:  The Mughals recruited diverse bodies of people in order to run the empire smoothly. Those who joined Mughal service were enrolled as mansabdars.

The term mansabdar referred to an individual holding a mansab, meaning a position or rank. It was a grading system used by the Mughals to fix rank, salary and military responsibilities.

The mansabdars were assigned to military responsibilities. For this they maintained a specified number of sowar or cavalrymen. The mansabdar brought his cavalrymen for review, got them registered, their horses branded and then received money to pay them as salary.

4. Why did the peasantry suffer a lot during the last years of Aurangzeb’s reign? [V. Imp.]
Answer:  Mansabdars, recruited by the Mughals to discharge Mughal services, received their salaries as revenue assignments known as jagirs. But most mansabdars did pot actually reside in or administer their jagirs. They only had rights to the revenue of their assignments which was collected for them by their servants while they served in some other part of the country.

Akbar managed to carefully assess these jagirs so that their revenues were roughly equal to the salary of the mansabdar. But Aurangzeb failed to do this. During his reign the actual revenue collected was often less than the granted sum. There was also a huge increase in the number of mansabdars, which meant a long wait before they received a jagir. These created a shortage in the number of jagirs.

As a result, many jagirdars tried to extract as much revenue as possible while they had a jagir. As Aurangzeb could not control these developments, the peasantry suffered a lot. They had to give the revenue under all circumstances which made their life miserable.

5. Write in brief about the Mughal Empire in the 17th century and afterward.[Imp.]
Answer:
(a) The influence and power of the Mughals were at the height during the 17th century. The sheen of their administrative and military efficiency brought great economic and commercial prosperity to the Empire. They had a huge treasure of wealth. They led a highly luxurious life. But the common mass had to face the curse of poverty.

( b) The Mughal emperors and their mansabdars spend a great deal of their income on salaries and goods. This expenditure benefited the artisans and peasantry who supported them with goods and produce. But the scale of revenue collection left very little for investment in the hands of the peasants and artisans. The poorest among them led a very miserable life. It was not possible for them to invest in additional resources like tools and supplies in order to increase productivity. However, the wealthier peasantry and artisanal groups, the merchants, and bankers profited in this economic world.

(c) The Mughal elites exercised a great deal of power in the late 17th century. With the decline of Mughal power and influence, many nobles became independent. They constituted new dynasties and held command of provinces, such as Hyderabad and Awadh.

Answer:  The Khaljis and Tughluqs raised people of humble birth who were often their clients, to high political positions. They were appointed as generals and governors. However, this also introduced an element of political instability. Slaves and clients, the people of humble birth, were loyal to their masters and patrons but not to their heirs. Now Sultans had their own servants. As a result the accession of a new monarch often saw conflict between the old and the new nobility.

5. Why did large parts of the subcontinent remain outside the control of the Delhi Sultans? What were the repurcussions? [V. Imp.]
Answer:  Large parts of the subcontinent remained outside the control of the Delhi Sultans because they were very far from Delhi. For example, it was difficult to control Bengal from Delhi. This helplessness of the Delhi Sultans paved the way for distant provinces to get independence. Even in the Gangetic plain there were forested areas that Sultanate forces could not penetrate. It was a golden opportunity for the local chieftains to establish their rule in these regions.

6. How did the chieftains arrange for their defence?
Answer:  The chieftains fortified themselves in mountains, in rocky, uneven and rugged places as well as in bamboo groves. The bamboo had unique features. It was strong and even fire could not affect it because its several party were intertwined making them very strong. The chieftains lived in these forests which served them as rampart. They had everything necessary for life such as cattle, crops, water, etc. inside the forests. Thus, they were safe. Only powerful armies could subdue them.

7. Why did Alauddin control the prices of goods in Delhi? What did he do for this?
Answer:  Alauddin gave great importance to his soldiers because it was they who could defend the Sultanate from outsiders. He decided to pay their salaries in cash rather than iqtas. The soldiers would buy their supplies from merchants in Delhi and it was thus feared that merchants would raise their prices. To stop this, Alauddin controlled the prices of goods in Delhi. For this Alauddin instructed officers to carefully survey prices. The merchants who did not sell their goods at the prescribed rates were punished.

8. Describe in brief Tughluq’s policy of ‘token’ currency.
Answer:  Tughluq did not control prices of the goods. Instead, he used a token currency, made out of cheap metals, and not of gold and silver. People in the 14th century did not believe in these coins. They saved their gold and silver coins and paid all their taxes to the state with this token currency. This cheap currency could be counterfeited easily.

9 Who was Sher Shah Sur? What do you know about his administration?[V. Imp.]
Answer:  Sher Shah Sur (1540—1545) established a powerful state. He started his career as the manager of a small territory for his uncle in Bihar and eventually challenged and defeated the Mughal Emperor Humayun. Sher Shah captured Delhi and established his own dynasty known as the Suri dynasty. Although the Suri dynasty ruled for only a short period i.e. 15 years, it introduced an administration that borrowed elements from Alauddin khalji and made them more efficient. The great emperor Akbar followed the techniques of Sher Shah’s administration while consolidating the Mughal Empire.

Long Answer Type Questions

1. Give an account of Alauddin’s administrative measures.              [V. Imp.]
Answer:  During the reign of Alauddin Khalji Mongol attacks increased. It was a huge administrative challenge for the Sultan. He introduced several administrative measures:

  1. Alauddin Khalji raised a large standing army as a defensive measure.
  2. He constructed a new garrison town known as Siri for his soldiers.
  3. The soldiers had to be fed. This was done through the produce collected as tax from lands between the Ganga and Yamuna. Tax was fixed at 50% of the pleasant’s produce.
  4. He paid his soldiers cash salaries rather than iqta. This was done in order to make soldiers able to buy their supplies from merchants in Delhi. It was feared that merchants would raise their prices. In order to stop this Alauddin controlled the prices of goods in Delhi. Prices were carefully surveyed by officers and merchants who did not sell at the prescribed rates were punished.

Alauddin’s administrative measures were successful because he efficiently withstood the threat of Mongol attacks.

2. Give an account of Muhammad Tughluq’s administration.
Answer:  The early years of Muhammad Tughluq’s reign faced Mongol attacks, which were curbed by Tughluq’s sincere efforts.

1. He took several administrative measures like Alauddin Khalji he also raised a huge standing army in Delhi.

2. He got emptied the oldest of the four cities of Delhi (Delhi-i Kunba) in order to garrison his soldiers there. The  residents of the old city were sent to the new capital of Daulatabad in the south.

3. He made arrangements for the collection of produce as tax to feed the soldiers. As it was very difficult to  maintain a large number of soldiers the Sultan levied additional taxes which coincided with famine in the area.

4. Muhammad Tughluq paid soldiers cash salaries. For this he introduced ‘token’ currency made of cheap metals. People in the 14th century did not trust these coins. They saved their gold and silver coins and paid  all their taxes to the state with this token currency.

3. ‘Muhammad Tughluq’s administrative measures were a failure’. Explain withexamples.
Answer:
Muhammad Tughluq’s administrative measures were a failure, we can prove this statement with following points:

  1. He campaigned into Kashmir which was finally a disaster. He then gave up his plans to invade Transoxiana and disbanded his large army.
  2. His administrative measures created problems. He shifted the residents of the old city to the new capital of Daulatabad in the south. People did not like this step taken by Muhammad Tughluq. They resented collectively.
  3. Tughluq, in order to meet the expense of maintaining a large number of soldiers, levied additional taxes which increased the burden of common people.
  4. The famine in the Ganga-Yamuna belt led to widespread rebellion.
  5. Muhammad Tughluq’s policy of ‘token’ currency also proved a failure. People of the 14th century did not trust this currency. They were very smart. They saved their gold and silver coins and paid all their taxes to the state with the token currency. This cheap currency could also be counterfeited easily.

Long Answer Type Questions

1. Write a note on Sultan Mahmud of Ghazni  [Imp.]
Answer:  Sultan Mahmud of Ghazni was a ruler of Afghanistan from 997 to 1030. He was an ambitious king and so made all efforts to extend his control over far off regions. He extended his control over parts of Central Asia, Iran, and the north­western part of the subcontinent. Almost every year he raided the subcontinent targeting wealthy temples. The temple of Somnath in Gujarat was the worst victim of his raids. Much of the wealth he carried away was used to create a splendid capital city at Ghazni. Ghazni was fond of knowing more about the people he conquered. He entrusted a scholar named al-Biruni to write an account of the subcontinent. The al- Biruni’s account, an Arabic work titled as Kitab al-Hind, is still an important source for historians.

2. How did the Cholas rise to power? Trace out the role of Rajaraja I in this rise.[V. Imp.]
Answer:  Cholas belonged to a minor chiefly family known as Muttaraiyar that held power in the Kaveri delta. They worked as subordinate to the Pallava kings of Kanchipuram.

Answer:  
Some of the major significant religious developments occurred in Hinduism.

The merchants and migrants brought with them the teachings of Quran, the holy book of Muslims.

Question 6. In what ways has the meaning of the term ‘Hindustan’ charged over the centuries?
Answer:
The meaning of the term ‘Hindustan’ has changed over the centuries in the following manner:

  1. In the thirteenth century Minhaj-i-Siraj used the term ‘Hindustan’. He meant areas of Punjab, Haryana and the lands between Ganga and Yamuna. He used this term in a political sense that were a part of the dominions of the Delhi Sultanate. The term never included South India.
  2. In the sixteenth century poet Babur used the term ‘Hindustan’ to describe the geography, the fauna and the culture of the inhabitants of the subcontinent.
  3. In fourteenth-century poet Amir Khusrau used the term ‘Hind’ in the same sense as Babur did in the sixteenth century.
  4. ‘Hindustan’ did not carry the political and national meanings as the term ‘India’ does today.

Answer:  
The term ‘pan-regional’ was used in the sense of the areas of empires spanning diverge regions. The dynasties like Cholas, Khaljis, Tughluqs, and Mughals extended their empires pan-regional. Though, not all these empires were equally stable or successful. But pan-regional rule altered the character of the regions. Most of the regions across the subcontinent were left with the legacies of the big and small states that had ruled over them. The emergence of many distinct and shared traditions in governance the economy elite cultures and languages were some of the prominent factors that took place as a result of pan-regional rules.

Question 9. What are the difficulties historians face in using manuscripts?
Answer:
Historians faced a lot of difficulties while using manuscripts because:

  1. There was no printing press in the 13th and 14th centuries. Scribes in those days made manuscripts by hand.
  2. To copy was not an easy exercise. Scribes could not read the handwriting of the other writers.
  3. They were forced to guess. So there were small but significant differences in the copy of the scribed.
  4. These small words or sentences here and there grew over centuries of copying.
  5. The manuscripts of the same text became a great extent different from the original.

Question 10. How do historians divide the past into periods? Do they face any problems in doing so?
Answer:
Historians divide the past into periods on the basis of continuity. This continuity is further based on:

  1. Coins
  2. Inscriptions
  3. Architecture
  4. Textual records

But they face difficulties in doing so as discontinuity exists.

  1. Textual records increased tremendously.

Thousand years of human history (or of any country or region) witnessed a number of changes. After all, the ancient history of India is different from that of the other two periods i.e., the medieval period and modem period. Therefore describing the entire period as one historical unit is not an easy task.

Map 1 and Map 2 given in the NCERT Textbook represent two different times. Map 1 was made in 1154 CE by al-Idrisi, an Arab geographer. This section is a detail of the Indian subcontinent from his larger map of the world. Map 2 was made by a French cartographer in 1720. Both maps are quite different from each other, even though they represent the same area. In Map 1 we find south India at the place where we would expect to find north India and Sri Lanka is the island at the top. The place names are in Arabic. Some familiar places like Kanauj in Uttar Pradesh have been spelt as Qanauj. In comparison to this Map 2 was made nearly 600 later after Map 1. By that time information about the subcontinent had changed a lot. This map appears to be more familiar to us. The coastal areas, particularly, are more detailed.

Question 12. Find out where records are kept in your village or city. Who writes these records? Is there an archive? Who manages it? What kinds of documents are stored there? Who are the people who use it?
