Ancient history

Long ago, people began to write.

This helped them keep track of things.

People learned to grow their own food. They kept animals like dogs and sheep.

This meant more people could live together.

They also found ways to use metal. Some made tools from copper. Others made strong tools from iron.

People made many new things. They made pots from clay. They even made wheels for carts.

Life changed in many lands. New cities grew near big rivers. It was a very busy time.

Ancient history began when people started writing.

This period lasted about 5,000 years. It started with Sumerian cuneiform. Cuneiform was a type of writing. Writing helped people keep records.

Before writing, people lived in prehistory. During this time, humans moved across the world. They reached Australia and Europe. They even reached the Americas. People also learned to farm. They grew crops like rice and wheat. They kept animals like dogs and sheep. This helped the number of people grow fast.

People also learned to use metal. They made things from copper and gold. Later, they made strong tools from iron.

Some people made wheels for carts. This helped them carry heavy loads.

Many great empires rose in West Asia. In Mesopotamia, early cities grew near rivers. The Achaemenid Empire was very large. It was led by Cyrus the Great.

They built roads to help people travel. In Anatolia, the Hittites used iron tools. They also used light chariots in war. These new tools changed how people lived.

Ancient history is a special time in our story. It covers about 5,000 years of human life. This era began when people first started writing things down. One of the first ways was Sumerian cuneiform script. This period lasted until the late antiquity era. It includes many different lands and many different people.

Before writing, humans lived in a time called prehistory. During this time, people moved to many new places. They reached Australia about 45,000 years ago. They moved to Europe and Japan later on. Humans even reached the Americas about 15,000 years ago. People also learned how to farm and keep animals. They grew crops like rice and millet. They kept dogs, sheep, and goats for help.

New tools changed how people lived and worked. People first used hammered copper for items. Later, they learned to make bronze around 3500 BC. This happened in Mesopotamia and also in China. Eventually, people learned to work with iron. The Hittites in Anatolia were very good at this. They used iron to make stronger tools and weapons. They also used light chariots with spoked wheels.

Many powerful empires rose in West Asia. Mesopotamia was home to some of the first cities. The Akkadian Empire reached its height around 2330 BC. Later, the Achaemenid Empire became very large. Cyrus the Great founded this great empire. He conquered many lands by 539 BC. His empire built roads to help people travel. This helped them move military forces very quickly.

These changes helped the world population grow. In 10,000 BC, there were only 2 million people. By 3000 BC, that number rose to 45 million. By the end of this period in AD 500, there were 209 million people. This shows how much the world changed. Humans learned to live together in big groups. They built great things that we still study today.

Ancient history is the study of the human story through recorded writing. This era spans roughly 5,000 years of human development. It begins with the invention of the Sumerian cuneiform script. This period continues through late antiquity, ending with the expansion of Islam. Ancient history covers all continents inhabited by humans during this time. It spans from approximately 3000 BC to AD 500.

Historians often organize this era using the three-age system. This system categorizes human progress into the Stone Age, Bronze Age, and Iron Age. Recorded history is usually considered to begin during the Bronze Age. The timing of these ages varies depending on the global region. In many places, the Bronze Age started a few centuries before 3000 BC. The end of the Iron Age also varies by location. Some regions finished the Iron Age in the early first millennium BC. Others continued into the late first millennium AD.

Before writing existed, humans lived in a time called prehistory. Much of our knowledge comes from the work of archaeologists. Early humans, known as Homo erectus, spread across Eurasia 1.8 million years ago. Modern humans, or Homo sapiens, emerged between 250,000 and 160,000 years ago. These humans migrated out of Africa approximately 50,000 years ago. They reached Australia by 45,000 years ago and Japan by 30,000 years ago. Humans finally migrated to the Americas about 15,000 years ago.

The Neolithic Revolution fundamentally changed how humans lived. This revolution involved the development of agriculture and animal domestication. Evidence of farming emerged around 9000 BC in eastern Turkey. People in the Fertile Crescent spread these new agricultural techniques. Humans domesticated dogs at least 15,000 years ago. Sheep and goats were domesticated around 9000 BC. By 7000 BC, people were cultivating cattle and water buffalo. The invention of the simple plough by 6000 BC increased efficiency. These advancements allowed humans to settle in one place.

Technological progress in metallurgy and transport further transformed societies. People initially used hammered copper for various items. Around 6000 BC, they discovered how to smelt copper ores. Alloy metallurgy began with the creation of bronze around 3500 BC. This happened in Mesopotamia and was later developed in China. The invention of the potter's wheel occurred between 5000 and 4000 BC. By 3000 BC, this technology was adapted into wheeled vehicles. These vehicles allowed people to carry much heavier loads.

Writing systems emerged independently in five distinct locations. These areas include Mesopotamia, Egypt, India, China, and Mesoamerica. By 3400 BC, proto-literate cuneiform was spreading in the Middle East. Egypt developed hieroglyphs by approximately 3200 BC. The Indus Valley Civilisation created the Indus script by 2800 BC. In China, the Oracle Bone Script appeared during the Shang dynasty. Mesoamerica saw the development of writing with the Zapotec civilization around 600 BC. Writing was essential for the complex administration of growing empires.

Mesopotamia is often called the cradle of civilization. It was the first region to practice intensive year-round agriculture. This area saw the rise of the first centralized governments and law codes. The surplus of storable food allowed for higher population densities. This density required an organized division of labor. This social organization led to the necessity of record keeping. Cities expanded through various periods, such as the Uruk and Early Dynastic periods.

Many powerful empires rose and fell across the Iranian plateau. The Achaemenid Empire was founded by Cyrus the Great. He conquered the Medes, Lydia, and Babylon by 539 BC. The empire built roads to improve communication and military movement. Darius the Great later expanded the empire to the Indus River. This became the largest empire in the world at that time.

Later, the Sasanian Empire rose in AD 224. They introduced new crops like sugar, rice, and cotton. The ancient period concluded as these systems evolved into new eras.

The impact of these changes is visible in population growth. In 10,000 BC, the world population was only 2 million. By 3000 BC, it had risen to 45 million. By 1000 BC, the population reached 72 million. By the end of the ancient period in AD 500, it was 209 million. Over 10,500 years, the population increased by 100 times. This massive growth reflects the success of ancient innovations.
