Chapter 4: Timeline and Sources of History
🌟 Introduction
History helps us understand how people lived in the past and how the present world has been shaped. It is often described as a connection between the past and present.
To study history properly, we need:
- A way to measure time → Timeline
- Evidence to know what happened → Sources of History
🕰️ 1. Timeline (Historical Time)
🔹 What is a Timeline?
A timeline is a line that shows events in the order in which they happened (chronological order).
👉 It helps us:
- Understand sequence of events
- Know which event happened first
- Compare different historical periods
🔹 How Time is Measured in History
📅 Calendar System
- The world mainly uses the Gregorian Calendar
-
Time is divided into:
- CE (Common Era) → After birth of Jesus Christ
- BCE (Before Common Era) → Before birth of Jesus Christ
👉 Example:
- 1947 CE → India got independence
- 560 BCE → Birth of Buddha
🔹 Important Time Units
- Year → 365 days
- Decade → 10 years
- Century → 100 years
- Millennium → 1000 years
🔹 Importance of Timeline
- Makes history easy to understand
- Shows development over time
- Helps in remembering dates and events clearly
🏺 2. Sources of History
🔹 What are Sources of History?
Sources are things that give us information about the past.
They can be objects, writings, or even stories.
👉 Without sources, we cannot know history.
🔹 Types of Sources of History
1. 🗣️ Oral Sources
Information passed by speaking:
- Stories
- Folklore
- Songs
- Traditions
👉 These are useful but sometimes not fully accurate.
2. 📜 Literary (Written) Sources
Written records of the past:
- Books and manuscripts
- Inscriptions
- Accounts by travellers
👉 These help us understand:
- Culture
- Society
- Events
3. 🏺 Archaeological Sources
Objects found by digging the earth:
- Tools
- Pottery
- Coins
- Buildings and monuments
👉 These give real physical evidence of history.
4. 🎨 Artistic Sources
- Paintings
- Sculptures
- Carvings
👉 These show:
- Lifestyle
- Art and culture
👨🔬 3. Who Studies History?
Different experts help us understand the past:
- Geologists → Study Earth (rocks, soil, mountains)
- Palaeontologists → Study fossils (plants & animals)
- Anthropologists → Study human culture and society
- Archaeologists → Study remains by digging
🧠 4. Why Sources are Important
Sources help us:
- Know about ancient life
- Understand culture and traditions
- Learn about technology and development
- Connect past with present
👉 Historians use different sources together to get a complete picture of history.
📝 5. Timeline + Sources Together
- Timeline tells “WHEN” something happened
- Sources tell “WHAT” and “HOW” it happened
👉 Both are needed to understand history clearly.
📌 Quick Revision Points
