Timeline and Sources of History

History is much more than just a list of dates and events; it's an ongoing conversation between what happened in the past and how we understand it today. As E.H. Carr wisely put it, history is "an unending dialogue between the present and the past." To truly grasp our current world, we must look back and understand the societies that came before us.

This chapter will help us explore three main questions:

• How do we organize and measure time in history?
• What different kinds of information help us understand the past?
• How did the very first humans live and develop?

How Do We Learn About the Past?

History is defined as the study of the human past. While the Earth itself has an incredibly long history, humans have only been a part of it for a relatively short period, though it feels like a very long time to us!

To uncover the secrets of the past, many dedicated people specialize in different areas of study:

• Geologists: These scientists study the physical features of the Earth. They examine things like soil, rocks, hills, mountains, rivers, seas, and oceans to understand how our planet has changed over millions of years.
• Palaeontologists: They focus on the ancient remains of plants, animals, and even humans. These remains, often found preserved in layers of soil or rocks, are called fossils. Palaeontologists help us understand prehistoric life forms.
• Anthropologists: Their work involves studying human societies and cultures. They look at how people lived, organized themselves, and developed their traditions from the earliest times right up to the present.
• Archaeologists: These are like detectives of the past. They study history by digging up and analyzing the physical remains that people, plants, and animals left behind. This can include tools, pots, beads, figurines, toys, bones, teeth, burnt grains, or even parts of ancient houses.

How Is Time Measured in History?

Different societies and cultures throughout history have developed their own unique ways of keeping track of time. Often, a significant event, such as the birth of an important leader or the start of a new ruler's reign, would mark the beginning of a new era, or a distinct period of time.

Today, the Gregorian calendar is the most widely used calendar system around the world. It organizes time into 12 months, adding up to 365 days, with a leap year every four years (though there's a special rule for century years like 1800 or 1900, which are only leap years if they are multiples of 400). Alongside this, many other calendars, like Hindu, Muslim, Jewish, and Chinese calendars, are still used, especially for calculating dates of festivals and other auspicious (favorable or bringing luck) events.

In the Gregorian calendar, time is typically measured in relation to the conventional date for the birth of Jesus Christ:

• CE (Common Era): This is now the standard term for years counted forward from this starting point. It replaced the older term 'AD' (Anno Domini, a Latin phrase meaning 'in the year of the Lord'). [!example] India gained independence in 1947 CE. This can also be written as 1947 AD.
• BCE (Before Common Era): These are the years counted backward from the conventional date of Jesus' birth. This term replaced 'BC' (Before Christ). [!example] Gautama Buddha was born around 560 BCE.

Calculating Years Between BCE and CE Dates

It's important to remember a key point about the Gregorian calendar: there is no 'year zero'. The year 1 CE immediately follows the year 1 BCE. This means that to calculate the number of years between a BCE date and a CE date, you need to add the two numbers together and then subtract one.

• Add the two years: 560 + 2024 = 2584
• Subtract one (because there's no year zero): 2584 - 1 = 2,583 years ago.

Understanding Timelines

A timeline is a very useful tool in history. It visually represents a sequence of dates and events over a particular period, from the beginning of humanity to the present. Timelines help us understand the order in which historical events occurred.

Longer Durations of Time

Besides individual years, we often use other terms to describe longer periods in history:

• Decade: A period of ten years.
• Century: A period of 100 years.
  • Centuries CE are counted starting from 1 CE. For example, the 21st century CE spans from 2001 to 2100.
  • Centuries BCE are counted backward from 1 BCE. For example, the 3rd century BCE includes the years 300 BCE to 201 BCE.
• Millennium: A period of 1,000 years.
  • Millenniums CE are counted from 1 CE. For example, we are currently in the 3rd millennium CE, which started in 2001 CE and will end in 3000 CE.
  • Millenniums BCE are counted backward from 1 BCE. For example, the 1st millennium BCE includes the years 1 BCE to 1000 BCE.

What Are the Sources of History?

Just like you might use old photographs, diaries, or family stories to learn about your own family's past, historians rely on a wide range of materials to reconstruct the past. Every object or structure from the past holds a story and acts like a piece in a giant jigsaw puzzle. However, it's important to remember that not all pieces of the historical puzzle may be found.

When historians (people who study and write about the past) investigate an event or a period, they carefully gather information from as many sources as possible. They compare these sources, sometimes finding that they confirm each other, and other times discovering contradictions. In such cases, historians must critically evaluate which sources are more trustworthy to re-create an accurate picture of the past.

Many experts contribute to uncovering and interpreting these historical sources:

• Archaeologists: As mentioned earlier, they dig up and study physical remains.
• Epigraphists: These specialists study ancient inscriptions, which are writings carved into stone, metal, or other hard surfaces.
• Anthropologists: They study human societies and cultures to understand the context of historical findings.
• Experts in literature and languages: They translate and interpret ancient texts and documents.

In recent decades, scientific studies have also become increasingly vital for historical reconstruction. For instance:

• Studies of ancient climates can tell us about environmental conditions.
• Chemical analyses of excavated materials reveal details about their composition and origin.
• Studies of genetics (how traits are passed down through generations) of ancient people provide insights into population movements and relationships.

For more recent history (the last two or three centuries), historians also consult modern sources such as newspapers and, more recently, electronic media like television and the internet.

The Beginnings of Human History

Modern humans (Homo sapiens) have been on Earth for approximately 300,000 years. While this seems like an incredibly long time, it's actually a very small fraction of the Earth's entire history.

Life of Early Humans

• Challenges and Group Living: Early humans faced constant challenges from nature. To survive, they lived in bands or groups, helping each other.
• Hunters and Gatherers: Their main way of life was hunting and gathering. They hunted animals and collected edible plants and fruits for their survival.
• Beliefs: Our early ancestors likely had beliefs about natural elements and possibly even a notion of an afterlife.
• Shelter and Communication: They lived in temporary camps, rock shelters, or caves. They communicated using languages that are now lost to us.
• Tools and Fire: Early humans learned to use fire and became skilled in making tools. They crafted improved stone axes, blades, arrowheads, and other implements to make their lives easier.
• Art and Ornaments: Evidence of their lives is seen in rock paintings found in caves worldwide. These paintings range from simple figures and symbols to detailed scenes of animals or humans. Over time, they also learned to make simple ornaments, such as stone or shell beads and pendants from animal teeth, which they sometimes exchanged with other groups.

The First Crops

The Earth's climate has undergone enormous changes over vast periods. There were times, known as an Ice Age, when much of the planet was covered in ice. The last major Ice Age occurred from over 100,000 years ago to about 12,000 years ago.

After the last Ice Age, the climate began to warm up. This warming caused much of the ice to melt, swelling rivers and eventually draining into the oceans. These improved living conditions marked a significant turning point for humans:

• Settling Down and Agriculture: In many parts of the world, humans began to settle down instead of constantly moving. They started cultivating cereals and grains, marking the beginning of agriculture.
• Domestication of Animals: Alongside farming, they also began to domesticate animals like cattle and goats.
• Community Growth: With a more stable and abundant food supply, human communities grew larger in size and number. They often chose to settle near rivers, not only for easy access to water but also because riverbanks provided more fertile soil, which made growing crops easier and more productive.

Development of Societies

As these agricultural communities grew, their social structures became more complex:

• Collective Welfare: Leaders, sometimes called 'chieftains', emerged to be responsible for the welfare (health, prosperity, and well-being) of the people. Everyone worked together for the community's benefit; for example, land was often collectively sowed and harvested, with no sense of individual ownership.
• Growth of Settlements: Small settlements, or hamlets, gradually grew into larger villages. These villages began to exchange goods, primarily food, clothing, and tools, with each other.
• Emergence of Towns and New Technologies: Over time, networks of communication and trade developed between villages, leading some to grow into small towns. New technologies also appeared, such as:
  • Pottery: The art of making pots and other objects from clay.
  • Metal Use: The discovery and use of metals, starting with copper and later iron, allowed for the creation of more durable tools, everyday objects, and ornaments.

This period of early human progress and the development of settled communities and new technologies laid the foundation for the emergence of what we call 'civilization'. It's a testament to the courage and persistence of our early ancestors that humanity survived many critical challenges and continued to evolve.
