Chapter - 1, TRACING CHANGES THROUGH A THOUSAND YEARS

Chapter - 1,  TRACING CHANGES THROUGH A THOUSAND YEARS

Map 1 – by Al-Idrisi (1154 CE):

  • Created by Arab geographer Al-Idrisi.
  • Shows the Indian subcontinent as part of a larger world map.
  • South India appears at the top – the map is upside down by today’s standards.
  • Place names are written in Arabic.
  • Reflects the knowledge and perceptions of the world from an Arab-Muslim perspective at the time.
  • Emphasis is not on geographical accuracy but on important trade routes and cities.

Map 2 – by a French Cartographer (1720s):

  • Made by a European (French) cartographer.
  • More modern and accurate in terms of shape and direction.
  • Uses European mapping techniques.
  • Names and directions are closer to what we see in modern maps.
  • North is shown at the top, as is common today.

Famous Place Names:

  • Kanauj in present-day Uttar Pradesh is visible in Al-Idrisi's map, written as Qanauj in Arabic.
  • Shows that some cities were already well-known centres of culture and power by the 12th century.

Comparison of Map 1 and Map 2 (Time Gap – ~600 years):

  • In the 600 years between the two maps, the knowledge about India grew significantly.
  • Map 2 (1720s) is more detailed, especially around coastal regions.
  • Reflects the influence of European exploration, trade, and colonization.

Purpose and Usage:

  • Map 2 was used by European sailors and merchants.
  • Helped them in navigation and trade during the Age of Exploration.
  • More scientific and practical in nature.

New and Old Terminologies – Important Notes

1. Language and Its Changing Nature:

  • Historical records were written in different languages over time (Sanskrit, Persian, Arabic, etc.).
  • These languages have changed significantly — not just in grammar and vocabulary, but also in meanings of words.

2. Example – The Term “Hindustan”:

  • Today: "Hindustan" usually means India as a country.
  • 13th century: Minhaj-i-Siraj used it to refer only to Punjab, Haryana, and the lands between the Ganga and Yamuna – in a political sense.
  • It did not include South India.
  • 16th century: Babur used "Hindustan" to describe India’s geography, animals, and people – more of a cultural and natural description.
  • Amir Khusrau in the 14th century used "Hind" in a similar sense.
  • The term "Hindustan" had no fixed meaning and did not carry a national identity like it does today.

3. Changing Meaning of “Foreigner”:

  • Today: A foreigner is someone from another country.
  • Medieval Period: A foreigner was anyone not from your village or community.
  • Could be from a different religion, caste, or region.
  • Example: A city dweller might consider a forest dweller a foreigner.
  • Words used:
  • In Hindi: Ajnabi or pardesi
  • In Persian: Ghair

4. Why This Matters for Historians:

  • Historians must be very careful when interpreting old terms.
  • Words used centuries ago might have different meanings than what we understand today.
 Historians and Their Sources
1. Sources Used to Study the Past (700–1750 CE):
  • Historians study different types of sources depending on the period:
  • Earlier periods (like Gupta or Harsha): used coins, inscriptions, architecture, and texts.
  • 700–1750 CE: These sources continued, but:
  • The number and variety of textual records increased greatly.
  • More written records became available due to cheaper paper.
2. Rise of Textual Records:- With the spread of paper, people wrote:
  • Holy texts
  • Chronicles of rulers
  • Letters and teachings of saints
  • Petitions, judicial records, account books, and tax registers
  • These records were collected in libraries and archives by:
  • Wealthy individuals
  • Temples
  • Monasteries
  • Rulers
3. Manuscripts and the Role of Scribes:
  • No printing press at that time – all manuscripts were handwritten.
  • Scribes copied texts manually, often introducing:
  • Errors
  • Changes in words or sentences (intentionally or by mistake)
  • Over time, these small differences grew, and:
  • Same text could look very different in different manuscripts.
Problem for Historians:
  • Since original versions are often lost, historians must:
  • Compare different versions of manuscripts.
  • Try to guess what the original text might have said.
4. Revisions by Authors:
  • Sometimes, even authors themselves revised their works.
  • Example: A 14th-century chronicler wrote one version of a text, then another version two years later.
  • These versions were different.
  • One version was lost for a long time, hidden in a library.
New Social and Political Groups
1. Period of Big Changes (700–1750 CE):
The period saw many developments in:- Technology, Agriculture, Trade, Society, Politics
New technologies introduced:
  • Persian wheel for irrigation
  • Spinning wheel for weaving
New crops introduced from other parts of the world:
  • Potatoes, corn, chillies, tea, and coffee
  • These changes came with the arrival of new people and ideas, leading to economic, social, and cultural transformations.
2. Mobility and Migration:
  • People moved across regions in search of wealth and opportunities.
  • The Indian subcontinent attracted many due to its richness and resources.
3. Rise of the Rajputs:- "Rajput" comes from "Rajaputra" meaning "son of a ruler".
  • Between the 8th and 14th centuries, the term described a group of warriors claiming Kshatriya status.
  • Included:- Rulers, chieftains, soldiers, and commanders
  • Rajputs were known for:- Valour,  Loyalty,  Heroism, praised by poets and bards

4. Rise of Other Groups:
  • Marathas, Jats, Sikhs, Ahoms, and Kayasthas also became influential.
  • Kayasthas were a caste of scribes and secretaries.
5. Agricultural Expansion and Social Changes:- Forests were cleared and agriculture expanded.
  • Forest dwellers either:- Migrated, Or became peasants (farmers).
  • These peasants became part of a complex social structure: Paid taxes,  Gave services and goods to landlords, priests, temples.
6. Social Differentiation and Jatis:- Society became divided into many groups or jatis (sub-castes). Status of jatis depended on:
  • Occupation
  • Family background
  • Region (status could vary from one place to another)
Each jati:
  • Had its own rules and customs
  • These were enforced by jati panchayats (assemblies of elders)
  • Jatis also followed village-level rules and were part of the larger state system.
Region and Empire
1. Large Empires and Diverse Regions:-  Some rulers built vast empires covering many regions of the Indian subcontinent.
  • Example: A ruler's empire extended from:
  • Bengal (Gauda) in the east
  • To Ghazni (Gajjana) in Afghanistan in the west
  • Included all of South India (Dravida)
2. Diversity of People and Places:
  • The empire included many different cultural and linguistic regions, such as:-  Gauda (Bengal), Andhra, Kerala, Karnataka, Maharashtra
  • People from these areas had their own identities, languages, and traditions.
3. Praising the King (Literary Sources):
  • Inscriptions and literary texts (like prashastis, or royal eulogies) praised the king.
  • These sources described the extent of the kingdom and glorified the ruler’s achievements.
4. Regional Identity by 700 CE:- By 700 CE, many regions had:
  • Their own geographical identity
  • Languages
  • Cultural features
  • These characteristics made each region distinct.
5. Rise of Pan-Regional Empires:- Powerful dynasties like:
  • Cholas, Khaljis, Tughluqs, Mughals
  • These empires ruled across many regions (called pan-regional empires).
6. Decline and Regional Re-Emergence:
  • When the Mughal Empire declined in the 18th century, many regional states re-emerged.
  • These regions were now shaped by the legacy of earlier large and small kingdoms.
7. Lasting Impact of Empires:- Empires influenced:
  • Governance, Economy, Elite culture, Language
  • These influences remained even after the empire ended.
8. Blending of Regional and Pan-Regional Cultures:
  • While regions developed their own identity, they also:
  • Felt the influence of larger empires (pan-regional forces)
  • Shared traditions across regions
  • But they never lost their distinct regional uniqueness.
 Old and New Religions
1. Major Religious Developments (700–1750 CE):
  • Religion during this time became both personal and collective.
  • It was often linked to social and economic life of communities.
  • As societies changed, so did their beliefs and religious practices.
2. Changes in Hinduism:
  • New forms of Hinduism emerged:
  • Worship of new deities
  • Temples were built by kings and rulers.
  • Brahmanas (priests) gained more power and social importance.
  • Rulers supported Brahmanas to gain prestige and legitimacy.
3. Emergence of Bhakti Movement:
  • A major religious change of this period.
  • Focused on:
  • Devotion to a personal god
  • Love and faith over rituals
  • Reaching God directly – no need for priests or elaborate ceremonies.
  • This made religion more inclusive and accessible.
4. Introduction and Spread of Islam:
  • Islam was introduced in India in the 7th century by:
  • Traders, Merchants, Sufi saints
  • Core beliefs of Islam:- One God (Allah), Belief in the Quran
  • Allah’s love and mercy applies to everyone, regardless of social background.
5. Islamic Traditions and Diversity:
  • Islam was supported by many rulers.
  • Theologians and jurists (religious scholars) helped develop Islamic traditions.
  • Different interpretations of Islam emerged:
  • Some believed Ali (Prophet Muhammad’s son-in-law) was the rightful leader – beginning of Shia tradition.
  • Others followed the early Khalifas – part of Sunni tradition.
  • Mystical traditions like Sufism also spread during this time.
Thinking About Time and Historical Periods
1. What is Historical Time?
  • Historians don't see time as just dates and years.
  • They study how ideas, beliefs, and societies change or continue over time.
  • To make history easier to understand, historians divide it into periods with common features.
2. Old British Periodisation:- In the 19th century, British historians divided Indian history into 3 periods:-  Hindu Period,  Muslim Period,  British Period
Problems with this system:
  • It focused only on the religion of rulers.
  • It ignored the rich diversity and everyday lives of people.
  • It is not used by modern historians anymore.
3. What Modern Historians Focus On:
  • Economic and social changes
  • Political developments
  • Religious transformations
  • Cultural shifts
  • For example, this book covers:
  • The rise of peasant societies
  • The growth of empires
  • The spread of Hinduism and Islam
  • The arrival of European traders
4. Medieval vs. Modern:
  • The period from 700 to 1750 CE is often called "medieval".
  • It is sometimes wrongly seen as unchanging or backward compared to the "modern" era.
  • But in reality, this period saw major economic, social, and political transformations.
  • Example: Indian regions became so prosperous that they attracted European traders.

5. Understanding Change and Continuity:
  • While reading history, look for:
  • What changed over time
  • What stayed the same (continuity)
  • Compare past events with what you see around you today.

CLASS - 6 Chapter - 1, Locating Places on the Earth

Chapter - 1, Locating Places on the Earth 

The globe of the Earth stands in space, made upof water, earth, fire and air and is spherical..... It is surrounded by all creatures, terrestrial as well as aquatic. ( Aryabhata - about--500 CE)

A Map and Its Components 

What is a Map?

  • A drawing of the Earth's surface (or a part of it) on a flat surface.
  • Maps give more detailed information than a globe.
  • Made using symbols, colors, scales, and directions.

An atlas is a book or collection of maps.

Types of Maps

  • Physical Maps:- Maps shows some natural features: mountains, rivers, plains, etc.
  • Political Maps:- Maps Show boundaries: countries, states, cities.
  • Thematic Maps:- Maps Show specific information: rainfall, population, crops, etc.

Components of a Map

1. Distance (Scale):- The relationship between distance on the map and actual distance on the ground.

Example: 1 cm on map = 10 km on ground.

Types of scales:

  • Small Scale: Large areas with less detail (e.g., country map).
  • Large Scale: Small areas with more detail (e.g., city map).

2. Direction:- Most maps show north at the top.

Cardinal Directions: North (N), South (S), East (E), West (W).

Intermediate Directions: NE, NW, SE, SW.

3. Symbols:- Used to show features like roads, rivers, railways, bridges, temples, etc.

A legend or key explains what each symbol means.

Symbols make maps easy to read and compact.

Mapping the Earth 

  • Mapping on the Earth is a little more difficult because our planet is not a flat surface. 
  • It nearly has the shape of a sphere.
  • It is slightly flattened at the poles.
  • Representing a sphere accurately on a flat sheet of paper is not possible.
  • The Earth is very big and round, so we can’t see or study all of it at once.
  • Maps and globes help us understand and locate places on Earth.

Understanding Coordinates:- Coordinates are a set of numbers (latitude and longitude) used to locate a place on Earth accurately.

1. Latitude:- Horizontal imaginary lines.
  • Measure north or south of the Equator (0° latitude).
  • Goes up to 90° North and 90° South.
  • Examples:
  • Tropic of Cancer: 23½° N
  • Tropic of Capricorn: 23½° S
2. Longitude:- These lines are called meridians of longitude.
  • Vertical imaginary lines.
  • Measure east or west of the Prime Meridian (0° longitude).
  • Goes up to 180° East and 180° West.
  • Prime Meridian passes through Greenwich, England.
3. How Coordinates Work
  • A place is located using both latitude and longitude.
  • Example: Delhi, India is located approximately at 28.6° N latitude and 77.2° E longitude.
  • Latitude + Longitude = Coordinate of a place
  • The point where latitude and longitude intersect gives the exact location.
  • Used in GPS, maps, and atlases.
Understanding Time Zones

Why Do We Have Time Zones?
  • The Earth rotates from west to east and completes one full rotation (360°) in 24 hours.
  • So, it rotates 15° every hour (360° ÷ 24 = 15°).
  • Because of this, different parts of the Earth experience day and night at different times.
  • To manage this, the world is divided into 24 time zones, each 15° apart.
Why do most countries adopt standard time?
Most countries adopt standard time to maintain a uniform time across the country, avoid confusion due to local times, and to ensure smooth running of transport, communication, business, and government activities.

What is GMT?:-  GMT stands for Greenwich Mean Time.
  • the time measured at the Prime Meridian (0° longitude), and it is used as the reference for all time zones in the world.
  • It is the base time for all the time zones in the world.
  • Countries calculate their own time by adding or subtracting hours from GMT.
  • Example: India is GMT + 5½ hours (Indian Standard Time).
What Is the International Date Line (IDL)?
  • The International Date Line (IDL) is an imaginary line on the globe that marks where the date changes by one day.
  • It is located at approximately 180° longitude.
  • When you cross the IDL from west to east, you subtract a day (go back one day).
  • When you cross from east to west, you add a day (go forward one day).
NCERT QUESTIONS
O1. Returning to page 10 and to Fig. 5.2 in Chapter 5 of this textbook, taking the scale to be 2.5 cm = 500 km, calculate the real distance from the estuary of the Narmada River to the estuary of the Ganga river. (Hint: round off your measurement on the map to an easy number.)

Answers:- Given:- Scale: 2.5 cm on the map = 500 km in real life

Distance on the map (between the estuaries of the Narmada and Ganga rivers): Let’s assume or round off the map distance to 6 cm (as suggested in the NCERT hint).
The real distance from the estuary of the Narmada River to the estuary of the Ganga River is approximately 1200 km.

Q2. Why is it 5:30 p.m. in India when it is 12:00 noon in London?
Answers: India is 82½° east of the Prime Meridian. Every 15° = 1 hour, so 82½° = 5½ hours. Hence, India is 5 hours 30 minutes ahead of London.

Q3. Why Do We Need Symbols and Colours in a Map?
Answers. We use symbols and colours in a map to show different features clearly, save space, and make the map easy to read. Symbols represent things like roads and rivers, while colours help identify landforms like mountains, water, and plains.

Q4. Find Out What You Have in the Eight Directions from Your Home and School?
Answers.  Main directions: North, South, East, West
Sub-directions: North-East (NE), South-East (SE), South-West (SW), North-West (NW).
Example:- From My Homeand school:

Direction                             (Home/School)What I See    
North                                             Park/Library
South                                         Grocery shop/Sschool Gate
East                                             Main road/School Field
West                                     Neighbor’s house/Staff Room
North-East (NE)                             Temple/Drinking Water
South-East (SE)                             Bus stop/Science Lab
South-West (SW)                      Community hall/Rest Room
North-West (NW)                     School playground/Music Room

Q5. What is difference between local time and standard time? discuss it in groups, with each group writing an answer in 100 to 150 words. compare your answers.
Answers. Difference Between Local Time and Standard Time
Local time is the time calculated for a particular place based on the position of the sun. When the sun is exactly overhead at a place, it is 12 noon there. This means each place along different longitudes can have a slightly different local time.

But using different local times for every city causes confusion. So, countries use a standard time, which is the time fixed for the whole country based on one central longitude. For example, in India, the standard time is based on 82½° E longitude and is called Indian Standard Time (IST).

Standard time helps with organizing transport, communication, and government activities across the country. Local time is mostly used in astronomy or older systems.

Q6. Delhi's and Bengaluru's latitudes are 29 degree N and 13 degree ; their longitudes are almost the same, 77 degree E. How much will be the difference in local time between the two cities?
Answers:- No, there will be no difference in local time.

Q7. Mark the following statements as true or false; explain your answers with a sentence or two. 

1. Do parallels of latitude have the same length?
A: False, parallels of latitude do not have the same length. The Equator is the longest, and the length of the parallels decreases as we move towards the poles.

2. Is the length of the meridian of longitude half of that of the equator?
A: False, the meridian of longitude runs from the North Pole to the South Pole, and it forms a semi-circle. It is not half the length of the Equator, as both are different in shape and orientation.

3. The South Pole has a latitude of 90° S.
A: True, the latitude of the South Pole is 90° S, which is the southernmost point on Earth.

4. In Assam, the local time and IST are identical.
A: True, the local time and Indian Standard Time (IST) are identical in Assam, even though Assam lies to the east of the IST meridian. India uses one standard time (IST) across the country, which is based on 82½° E longitude.
While some regions in Assam, particularly tea gardens, have historically used a time zone one hour ahead of IST (Chaibagan or "Tea Garden Time"), this is an informal practice and does not represent the official time zone for the state. The official time zone for Assam, as well as the rest of India, is IST.

5. Lines seperating the time zonnes are identical with meridians of longitudes.
Answer: True, the lines separating time zones are based on meridians of longitude, but they are not always identical to them.

6. The Equator is also a parallel of latitude.
A: True, the Equator is the zero-degree parallel of latitude, dividing the Earth into the Northern and Southern Hemispheres. It is the longest parallel of latitude.
