Chapter 4. Timeline and Sources of History

1. Understanding History

History is the study of the human past. It helps us understand how people, societies and civilisations developed over time.

  • History helps us understand the present through the study of the past.
  • The Earth has a very long history, while human history forms only a small part of it.
  • Many experts study different aspects of the past.
  • Different types of evidence help us reconstruct the history of human societies.

2. People Who Study the Past

Different specialists study different aspects of the Earth's and human past.

Geologists

Geologists study the physical features of the Earth.

  • They study soil and stones.
  • They study hills and mountains.
  • They study rivers, seas and oceans.
  • Their studies help us understand the physical history of the Earth.

Palaeontologists

Palaeontologists study the remains of plants, animals and humans from the distant past, especially through fossils.

  • They study fossils preserved in layers of soil or rocks.
  • Fossils may include footprints or parts of plants and animals.
  • Their studies help us understand life in the distant past.

Anthropologists

Anthropologists study human societies and cultures from the oldest times to the present.

  • They study human communities.
  • They study cultures and ways of life.
  • They help us understand how human societies changed over time.

Archaeologists

Archaeologists study the past by examining remains left behind by people, plants and animals.

  • They may excavate tools and pots.
  • They study beads, figurines and toys.
  • They examine bones and teeth of animals and humans.
  • They may study burnt grains.
  • They examine parts of houses, bricks and other remains.

3. Important Terms Related to the Study of the Past

Term Meaning
Fossils Impressions or parts of plants or animals preserved within layers of soil or rocks.
Era A distinct period of time.
Archaeology The study of the past through material remains left behind by people and other living beings.
Anthropology The study of human societies and cultures.
Palaeontology The study of ancient life through fossils and preserved remains.

4. How Is Time Measured in History?

Different societies and cultures have developed different ways of measuring time. Important events have often been used to mark the beginning of a new era.

  • Time is essential for understanding the sequence of historical events.
  • Different cultures have used different calendars.
  • Important events may be used as reference points for measuring historical time.
  • Today, the Gregorian calendar is widely used around the world.
  • Other calendars, such as Hindu, Muslim, Jewish and Chinese calendars, are also used.

5. Gregorian Calendar

The Gregorian calendar is the calendar commonly used in most parts of the world today.

  • It has 12 months.
  • A normal year has 365 days.
  • A leap year normally occurs every four years.
  • A leap year has 366 days.
  • The extra day is added to February.
  • Century years are treated differently when deciding whether they are leap years.
  • A century year is a leap year only when it is divisible by 400.

Examples:

  • 2000 was a leap year because it is divisible by 400.
  • 1800 was not a leap year.
  • 1900 was not a leap year.

6. AD, CE, BC and BCE

Historical dates are commonly expressed using CE and BCE. These terms correspond to the older terms AD and BC.

Term Full Form Meaning
AD Anno Domini Traditionally used for years after the conventional birth of Jesus.
CE Common Era Commonly used for the same era as AD.
BC Before Christ Traditionally used for years before the conventional birth of Jesus.
BCE Before Common Era Commonly used for the same period as BC.
  • CE and BCE are widely used in modern historical writing.
  • Years in the BCE period are counted backwards.
  • There is no year zero between 1 BCE and 1 CE.

7. No Year Zero

The Gregorian calendar has no year zero.

  • 1 BCE is immediately followed by 1 CE.
  • There is no 0 CE or year zero between them.
  • This must be remembered while calculating the number of years between BCE and CE dates.

Rule for Calculating Years Between BCE and CE

When calculating the number of years between a BCE date and a CE date:

Number of years = BCE year + CE year − 1

Example:

Years between 2 BCE and 2 CE:

2 + 2 − 1 = 3 years

Therefore, only three years pass between 2 BCE and 2 CE because there is no year zero. :contentReference[oaicite:1]{index=1}

8. Timeline

A timeline is a useful tool for showing dates and historical events in their chronological order.

  • A timeline places events in the order in which they occurred.
  • It helps us understand the sequence of historical events.
  • It helps us compare events from different periods.
  • It can include both BCE and CE dates.
  • Historical events can be marked at their appropriate positions on a timeline.

9. Decade

A decade is a period of 10 years.

  • 1 decade = 10 years.
  • For example, the period from 2010 to 2019 represents a decade.

10. Century

A century is a period of 100 years.

  • 1 century = 100 years.
  • The 1st century CE includes the years 1 CE to 100 CE.
  • The 2nd century CE includes the years 101 CE to 200 CE.
  • The 21st century CE began in 2001 CE and will end in 2100 CE.

Important Rule

The century number is generally one more than the first two digits of a year, except when the year ends in two zeros.

Examples:

  • 2024 CE belongs to the 21st century CE.
  • 1900 CE belongs to the 19th century CE.
  • 2000 CE belongs to the 20th century CE.
  • 2001 CE began the 21st century CE.

11. BCE Centuries

BCE centuries are counted backwards from 1 BCE.

  • The 1st century BCE includes 100 BCE to 1 BCE.
  • The 2nd century BCE includes 200 BCE to 101 BCE.
  • The 3rd century BCE includes 300 BCE to 201 BCE.

Thus, the numbers become larger as we move further back in BCE time. :contentReference[oaicite:2]{index=2}

12. Millennium

A millennium is a period of 1,000 years.

  • 1 millennium = 1,000 years.
  • The 1st millennium CE includes 1 CE to 1000 CE.
  • The 2nd millennium CE includes 1001 CE to 2000 CE.
  • The 3rd millennium CE began in 2001 CE.
  • The 3rd millennium CE will continue up to 3000 CE.

Millennia in the BCE period are also counted backwards from 1 BCE. :contentReference[oaicite:3]{index=3}

13. Indian Calendars

India has a long tradition of using calendars based on astronomical observations.

  • Many traditional Indian calendars use the positions of the Sun and Moon.
  • The movement and positions of celestial bodies help define months and other periods.
  • Different regions and traditions may follow different calendar systems.

14. Pañchānga

A pañchānga is a traditional Indian calendar or book of tables containing information about days, months and astronomical events.

  • It provides information about days and months.
  • It contains related astronomical data.
  • It can predict solar eclipses.
  • It can predict lunar eclipses.
  • It gives information about sunrise and sunset.
  • Many pañchāngas provide weather predictions.
  • They also provide dates and timings of festivals.
  • Pañchāngas continue to be widely used in India. :contentReference[oaicite:4]{index=4}

15. Important Differences

  • Modern humans are known as Homo sapiens.
  • Homo sapiens have lived on Earth for about 300,000 years.
  • Early human history forms only a small part of the Earth's very long history.

32. Life of Early Humans

Early humans faced many challenges from nature and developed ways of living together to survive.

  • Early humans lived in bands or groups.
  • Living in groups helped them support and protect one another.
  • They constantly searched for shelter and food.
  • They were mainly hunters and gatherers.
  • They hunted animals for food.
  • They collected edible plants and fruits.
  • They had beliefs related to natural elements.
  • They may also have had some notion of an afterlife.

Afterlife: A life that begins after death. :contentReference[oaicite:12]{index=12}

33. Early Human Settlements

Early human groups lived in temporary settlements and used natural shelters.

  • They lived in temporary camps.
  • They lived in rock shelters.
  • They also lived in caves.
  • They communicated using languages that are now lost.
  • These settlements provided protection from natural conditions.

34. Fire and Tools

Early humans used fire and developed tools that made their lives easier.

  • Fire was an important part of early human life.
  • They improved their stone tools over time.
  • Stone axes were used as tools.
  • Blades were developed for different purposes.
  • Arrowheads were also made.
  • Tools helped early humans in their daily activities and survival.

The chapter specifically mentions improved stone axes, blades, arrowheads and other tools. :contentReference[oaicite:13]{index=13}

35. Rock Paintings

Rock paintings provide important evidence about the lives and activities of early humans.

  • Rock paintings have been found in hundreds of caves around the world.
  • Some paintings contain simple human figures.
  • Some contain symbols.
  • Others show detailed scenes.
  • Animals and humans are represented in many paintings.
  • Rock paintings help us understand aspects of early human life.

36. Ornaments of Early Humans

Early humans also developed simple forms of personal ornaments.

  • They made beads from stone or shells.
  • They made pendants from animal teeth.
  • Some ornaments may have been exchanged with other groups.
  • These objects provide evidence about the skills and social interactions of early humans.

:contentReference[oaicite:14]{index=14}

37. Ice Age

The Earth's climate has changed many times over long periods. During some periods, the Earth became extremely cold and large areas were covered with ice. Such a period is called an Ice Age.

  • An Ice Age is a period of very cold climatic conditions.
  • Large parts of the Earth were covered with ice during an Ice Age.
  • When the climate later became warmer, some of the ice melted.
  • The resulting water increased the flow of existing rivers.
  • The last Ice Age lasted from over 100,000 years ago to around 12,000 years ago.

:contentReference[oaicite:15]{index=15}

38. Beginning of Agriculture

After the last Ice Age, living conditions improved for humans in many parts of the world. People gradually began settling down and cultivating crops.

  • People began settling down instead of constantly moving from place to place.
  • They started cultivating cereals and grains.
  • Agriculture provided a more regular source of food.
  • Growing communities became larger as food availability increased.

39. Domestication of Animals

Along with agriculture, people began domesticating animals.

  • Cattle were among the animals domesticated by early communities.
  • Goats were also domesticated.
  • Domesticated animals became part of settled human life.
  • Animal domestication contributed to the growth of agricultural communities.

40. Settlements Near Rivers

Many early agricultural communities settled near rivers.

  • Rivers provided a reliable source of water.
  • The soil near rivers was often more fertile.
  • Fertile soil made growing crops easier.
  • Availability of water and fertile land supported the growth of settlements.
  • As food became more available, communities grew in size and number.

:contentReference[oaicite:16]{index=16}

41. Growth of Villages and Communities

As communities grew, their social organisation became increasingly complex.

  • Leaders or chieftains became responsible for the well-being of the people.
  • People collectively worked towards the welfare of the community.
  • In some communities, there was no sense of individual ownership.
  • Land was collectively sown and harvested.

Welfare: Health, prosperity and well-being.

42. From Hamlets to Villages and Towns

Over time, small settlements developed into larger villages and some villages eventually grew into small towns.

  • Hamlets were small settlements.
  • Hamlets gradually grew into sizeable villages.
  • Villages exchanged goods with one another.
  • Commonly exchanged goods included food, clothing and tools.
  • Networks of communication and exchange developed between villages.
  • Some villages eventually developed into small towns.

Hamlet: A small settlement or small village. :contentReference[oaicite:17]{index=17}

43. Development of New Technologies

Growing communities developed new technologies that improved daily life.

  • Pottery was developed for making pots and other clay objects.
  • Metal was later used to make stronger and more durable objects.
  • Copper was used before iron.
  • Iron was used later in the development of metal technology.
  • Metal helped people make durable tools.
  • Metal was also used for objects of daily use.
  • Metal was used for making ornaments.

44. From Villages to Civilisation

The growth of settlements, trade, technology and social organisation gradually prepared the way for the emergence of civilisation.

  • Communities became larger and more socially complex.
  • Villages developed communication and exchange networks.
  • Some villages developed into towns.
  • Pottery and metal technology developed.
  • Social organisation became more complex.
  • These developments prepared the way for the emergence of civilisation.

The chapter states that the next chapter will explore the stage at which civilisation emerged. :contentReference[oaicite:18]{index=18}

45. Early Human Progress and Challenges

The development of human societies was not easy. Early humanity faced many challenges and depended on courage and persistence for survival.

  • Early humans faced many challenges from nature.
  • Human communities had to adapt to changing conditions.
  • Some earlier human species disappeared.
  • The survival of modern humans was connected with their ability to face challenges.
  • The courage and persistence of early humans contributed to the continuation of humanity.
