Complete Notes & Free Quiz

People study history to know about the past and to make sense of the current world. The events of the past enable us to understand their impact on the present world. By studying past events, we can understand why things are the way they are today — including cultures, borders, governments, and ways of life.

Prehistory is the period of human history without written records — the time before humans developed writing. We learn about prehistory mainly through archaeological discoveries, study, and research. Since there are no written records, historians rely on physical remains such as tools, bones, pottery, and ruins.

The term 'civilization' describes the society, culture, and way of life of people living in a certain area at a specific time. Its features include beliefs, governance, art, architecture, and law.

Most civilizations originated near rivers because rivers provided water and fertile land. When rivers flooded, alluvial soil (rich, fertile soil deposited by floodwater) was deposited on surrounding land, making it highly suitable for growing crops.

Historians identify six key components of a civilization:

1. Urban Centers — cities with surplus food supply
2. Government — to rule and administer territories
3. Social Order — division of society into classes
4. Beliefs — religion and cultural traditions
5. Art — monuments, architecture, ruins
6. Writing — communication and record keeping

The four major river valley civilizations:
1. Mesopotamia — between the Tigris and Euphrates rivers (6000–2500 BCE)
2. Ancient Egypt — along the River Nile (3500–50 BCE)
3. Indus Valley — along the River Indus (3000–1200 BCE)
4. Chinese Civilization — along the Yellow River (2500 BCE–100 CE)

The word Mesopotamia is Greek for "the land between two rivers" — the Tigris and the Euphrates. Mesopotamia is located in modern-day Iraq. It was one of the earliest cradles of civilization and home to the Sumerian and Babylonian cultures.

Sumerian society was divided into three main classes:

1. Upper Class — priests, landowners, and government officials
2. Middle Class — traders, craftsmen, and artisans
3. Lower Class / Slaves — farmers, servants, and slaves

Priests held great power as they interpreted the will of the gods and controlled temple lands.

The Sumerians made remarkable contributions:

• The Wheel — first used for pottery, later for transportation
• Cuneiform Writing — the world's first known writing system
• Irrigation systems — canals to bring water to crops
• The Plough — for farming
• The Ziggurat — a stepped temple structure, center of city life
• A numerical system based on 60 (we still use 60 seconds/minutes today)

Cuneiform was the world's first known writing system, invented by the Sumerians. It consisted of wedge-shaped marks pressed into soft clay tablets using a reed stylus. Once dried, the clay became a permanent record.

Cuneiform was used for: recording trade transactions, writing laws, religious texts, and historical accounts. It was a revolutionary advancement because it allowed knowledge and history to be preserved across generations.

The Sumer Valley Civilization declined due to several factors:

• Soil salinization — over-irrigation made the soil too salty to grow crops
• Invasion by Akkadians under Sargon of Akkad (~2334 BCE)
• Internal conflict among city-states
• Natural disasters including floods and droughts

The Akkadian Empire absorbed Sumer, leading to the rise of later empires like Babylon.

The Babylonian Civilization was centered around the city of Babylon on the Euphrates river in Mesopotamia.

Key features: a highly organized government, a complex legal system, advanced mathematics and astronomy, the Hanging Gardens of Babylon (one of the Seven Wonders), and a powerful trade network. The Babylonians built on Sumerian achievements and expanded their empire significantly.

Sargon of Akkad (ruled ~2334–2279 BCE) was one of the world's first empire builders. He conquered the Sumerian city-states and united all of Mesopotamia under one rule, creating the Akkadian Empire — believed to be the world's first multi-national empire.

He was significant because he demonstrated that different city-states could be governed under a centralized power.

Nebuchadnezzar II was the greatest king of the Neo-Babylonian Empire (ruled ~605–562 BCE). He is famous for:

• Building the Hanging Gardens of Babylon (one of the Seven Wonders of the Ancient World)
• Rebuilding the city of Babylon into one of the most magnificent cities of the ancient world
• The Destruction of Jerusalem and the Babylonian Captivity of the Jews (~586 BCE)

Hammurabi was the sixth king of Babylon (ruled ~1792–1750 BCE) who united all of Mesopotamia under Babylonian rule.

The Code of Hammurabi was one of the earliest and most complete written legal codes in world history. It consisted of 282 laws inscribed on a large black stone stele. Key principles:

• "An eye for an eye, a tooth for a tooth" — punishments matched the crime
• Different penalties for different social classes
• Laws covered trade, property, marriage, and criminal behavior

It was significant because it established the principle that law applies to everyone and that rulers must be accountable.

Historians use two types of sources:

Primary Sources — original, first-hand records created at the time of the event. Examples: artefacts, clay tablets, diaries, paintings, cuneiform inscriptions, archaeological remains.

Secondary Sources — accounts written after the event, based on primary sources. Examples: textbooks, biographies, documentaries, history books.

Because historians rely on both, their interpretations of the same event sometimes vary.
