Brief History of Human Civilization

3.1 Early Civilization 2070

The history of early human civilization can be divided into the following ages:

A. Stone Age (2.5 million years ago – 3500 BC)

• Age prior to the beginning of civilized society, began in Africa.
• Began with use of stones as weapons along with wood, animal bone, and horn.
• Nomadic culture: Humans moved from place to place searching for food.
• Cereal cultivation and animal domestication began.
• At the end, land gradually evolved to towns and finally into cities.

B. Bronze Age (3500 BC – 1100 BC)

• First civilization in Mesopotamia.
• Discovery of copper and alloyed with tin to get bronze.
• Many civilizations flourished: Egyptian, Sumerian, Maya, Assyrian.
• Civilizations in China and India were developed.
• Spreading of Aryans from central Europe to Asia.
• Navigation technology was developed.
• Invention of first writing system by Sumerians and picture writing system by Egyptians.
• Old Babylonian and Akkadian empires were developed.
• Constructions of temples, tombs, war chariots.

C. Iron Age (1100 BC – 500 AD)

• Main ingredient of weapons was iron.
• Historical figures: Gautama Buddha (550 BC), Confucius and Lao Tzu in China (6th century BC), Emperor Ashoka, Jesus Christ.
• Victory of Aryans over the whole ancient world.
• Development of iron technology.
• Beginning of Science: gathering information, analyzing, and solving problems.
• Greek and Roman civilizations were developed.
• Greek philosophers: Plato, Aristotle, Socrates.

D. Middle Age (500 AD – 1450 AD)

• Beginning of Islamic religion; Prophet Muhammad dictated the Koran.
• Islamic invasion took place.
• Vikings invasion (~700 AD).
• Mongolian conquest: Genghis Khan (1200 AD) conquered China, Turkmenistan, Persia, Armenia, parts of India.
• Revival of European intelligence.
• Commercial and industrial activities developed; growth of cities and trading.
• Silk Road linked Asia and Europe for trading.
• Universities at Paris, Oxford, Bologna were established.
• Exploration: Marco Polo travelled throughout Asia.

E. Towards the Modern World (1450 AD – 1660 AD)

• Birth of scientists: Leonardo da Vinci, Galileo, Newton, Robert Hooke.
• Columbus discovered America in 1492 AD.
• Age of mechanical revolution and technological development.
• Advances in education throughout the westernized world.
• Inventions: sawmill, microscope, telescope, clocks.

3.2 Great Renaissance of Europe (1300s–1600s) 20772071

Renaissance means "re-birth" in French. It was the time period following the Middle Ages that lasted from the 1300s to 1600s. As the renowned Rome fell and the feudal structure came and went, a new period emerged known as the renewal of arts — "The Renaissance." There was a renewed interest in learning about ancient Greeks and Romans. The Renaissance had its beginnings in Italy.

Key Features:

1. Geography: Italy's Venice and Genoa were major trade centres of both physical products and ideas. Money earned from trade financed Italy's research and exposure to science and arts. Adequate food production gave citizens more time for science and art.
2. Science: Technology developed significantly — telescope and printing press (developed by Johann Gutenberg from Germany). People started to divide science and religion. Nicolas Copernicus proved Earth was not the centre of the solar system. Galileo Galilei was sentenced to house arrest for confirming Earth revolves around the Sun.
3. Music: Distinguished by graceful flowing melodies written solely for voice. It was the golden period of Acapella style.
4. Arts: Many artists preferred nude style of painting and sculpting. Famous works: David by Michelangelo (1501–1504), Sistine Chapel, Leonardo da Vinci's Mona Lisa. Leonardo was also an inventor, designer, engineer, and scientist — first to design helicopter, tank, parachute, and flying machine.
5. Politics: Run by ideology of despotism. City-states (Venice, Genoa, Milan, Florence, Lucca, Pisa) were self-governing and self-sufficient. They became wealthy through trade, commerce, and capitalism. Italy later declined when Ottomans took over the Byzantine Empire, cutting trade with Asia.
6. Philosophy: Humanism originated during Renaissance. Humanists were attentive to goals about being human rather than religious matters. Francesco Petrarch was one of the first Humanists. Great value was placed on education — artists, architects, leaders, writers, and scientists were greatly admired.

Role of Renaissance in Development of Science & Technology: The Renaissance directly paved the way for modern science and technology by: (a) reviving the scientific method of observation and experimentation (Galileo, Copernicus), replacing medieval reliance on religious authority; (b) inventing transformative technologies — Gutenberg’s printing press (c. 1440) democratized knowledge, the telescope enabled astronomical discovery, and Leonardo da Vinci’s engineering designs (helicopter, tank, parachute) anticipated modern machines by centuries; (c) creating an intellectual culture that valued inquiry, education, and innovation — the foundation on which the later Scientific Revolution and Industrial Revolution were built.

3.3 Early Part of Industrial Revolution (1660–1815) 2080207920732070

The Industrial Revolution was the transition to new manufacturing processes in the period from about 1660 to 1815. The transition included going from hand production methods to machines, new chemical manufacturing and iron production processes, the increasing use of steam power, the development of machine tools, and the rise of the factory system. It began in towns across UK and USA where a series of astonishing inventions transformed the method people lived and worked.

3.3.1 Impacts of the Industrial Revolution 2070

1. Population Increase: There was a simultaneous increase in both population and per capita income. Europe's population increased from about 100 million in 1700 to 400 million by 1900.
2. Urbanization: Shift of population from rural to urban residency. Growth of modern industry since late 18th century led to massive urbanization and the rise of new great cities.
3. Impact on Women & Family Life: Capitalism lowered the status of women. Middle and upper-class women were confined to domestic life; lower-class women were forced to take poorly-paid jobs.
4. Child Labour: Limited opportunity for education; children were expected to work. Employers paid children less than adults despite comparable productivity. In 1788 England and Scotland, two-thirds of workers in cotton mills were children.

3.3.2 Environmental Consequences 2080

1. Air Pollution: Factories and combustion of fossil fuels (coal for steam engines) released gases and toxins into the atmosphere.
2. Water Pollution: Industrial waste, oil spills, acid rain, and urban runoff contaminated water bodies.
3. Soil Pollution: Industrial waste deprived soil of essential nutrients.
4. Deforestation: Demand for fuel (charcoal, wood) and land for factories led to clearing of forests, disrupting ecosystems and natural carbon sinks.
5. Resource Depletion: More mines were discovered for coal and iron for steam engines, causing significant environmental damage.
6. Global Warming: Increased emission of greenhouse gases (CO2) from burning fossil fuels began the long-term trend of rising global temperatures.

3.3.3 Important Technological Developments 2073

1. Textiles: Mechanized cotton spinning powered by steam or water increased worker output. James Hargreaves invented the 'spinning jenny' (~1764) enabling production of multiple spools simultaneously. The power loom was developed in the 1780s. One machine could do the work of 50 people.
2. Steam Power: Switch from water to steam power sped up manufacturing, transportation, and farming. Steam engines were used in railroads and steamboats. More mines were discovered for coal and iron.
3. Iron Making: Substitution of coke for charcoal lowered the fuel cost of pig iron and wrought iron production. Cast iron blowing cylinder first used in 1760.
4. Machine Tools: First machine tools included screw-cutting lathe, cylinder boring machine, and milling machine. Made economical manufacture of precision metal parts possible.
5. Other Areas: Chemicals, agriculture, paper machines, mining, railways and roads, canals, cement.

3.3.4 Industrial Revolution in America

• Samuel Slater memorized English machinery designs, moved to USA, and opened a spinning mill in 1790.
• In 1814, copies of industrial power looms were produced.
• Eli Whitney invented the cotton gin in 1793, making cotton farming the backbone of Southern US wealth.

3.3.5 Impacts in Nepal

• Nepal had a rich tradition of handmade textiles (rugs, bags, blankets, pashmina, embroidery).
• Industrialization led to mass-produced goods at lower cost, reducing demand for handmade items.
• Nepal was largely isolated but still affected — handmade textiles faced competition from power looms.
• The country was late to begin its own industrialization, making competition with nations like China difficult.

3.7 Climate Change as a Threat to Human Civilization 2079

Climate change has become a serious threat to human civilization. Justification with examples:

1. Widespread Drought: Greenhouse gas emissions increase air temperatures, increasing evaporation. Example: prolonged droughts in Sub-Saharan Africa affecting millions.
2. Infectious Diseases: Rising temperatures create ideal conditions for virus replication. Example: Dengue fever spread increased 3–5.9% globally compared to 1990 levels.
3. Food Insecurity: Higher CO2 affects vegetation growth; extreme weather disrupts food production and distribution. Example: crop failures from flooding and drought.
4. Extreme Weather Events: Increased flooding, storms, heat waves. Example: every 1°C increase in sea temperature = 31% increase in strong storm frequency. Vulnerable populations (children, elderly, poor) are disproportionately affected.
5. Rising Sea Levels: Melting polar ice caps threaten coastal cities. Example: White Chuck Glacier retreated 1.9 km in 30 years.
6. Health Impacts: Ground-level ozone increase causes asthma and respiratory diseases; mental health impacts (PTSD, depression) from disasters.
