The Tertiary Sector: Services and Economic Growth

The Tertiary Sector does not produce material goods. Instead, it provides essential services to people and other economic sectors. Examples include health care and education.

Growth and Importance in Developed Nations

In developed countries, the tertiary sector has undergone significant growth, both in terms of the number of people employed and the wealth generated, making it the most important economic sector today. This expansion coincided with the emergence of the Information Society.

Low-End Tertiary Services

The Low-End Tertiary Sector consists of jobs that require little specialized training and are usually poorly paid. Examples include cleaners and street traders.

Skilled Services and Professional

Growth of Medieval Cities

• Improvement in agriculture, particularly **ploughing** techniques.
• Increased food supply led to population growth, transforming towns into cities.
• This growth began in countries such as Italy, where ancient cities founded by the **Romans** had never completely disappeared.
• Urban areas also grew up in new places, such as Russia and Scandinavia.
• Cities often lacked a sewer system.
• Inside the city walls, houses were **crowded** together and streets were narrow.
• The center of daily life was the square, where the market was held.
• Monasteries and convents were also built in urban areas.
• Universities were founded, replacing monasteries as the main source of knowledge.

The Spanish Arrival in the Americas (1492)

Christopher Columbus set sail from the port of Palos (Huelva) on 3rd August 1492, heading for the Canary Islands. The expedition comprised three ships (one nao and two caravels) and approximately three hundred men.

They arrived at Guanahani Island in the Bahamas, which Columbus named San Salvador. To impose their sovereignty on the discovered territories, the Catholic Monarchs requested a papal bull from the Pope. The Kingdom of Portugal protested, leading to an agreement: the signing of the Treaty of Tordesillas in 1494, which divided the newly discovered lands between Spain and Portugal.

Exploitation Colonies: They had economic value. The indigenous population was governed and economically exploited by a white minority originating from the colonizing country. For example, India and Great Britain.

Settler Colonies: They had a socio-economic value. The majority were emigrants from the colonizing country, and they were considered overseas provinces with governmental autonomy. For example, Canada, Australia, and New Zealand under British control.

Protectorates: They were areas of strategic interest. The indigenous population maintained its own government and administration but under the supervision of the colonizing power. For example, Morocco was a protectorate of France and Spain.

The Evolution of Modern Industry

The First Industrial Revolution (c. 1770–1850)

Modern industry began in Great Britain. Industrial labor was carried out by machines, generally powered by steam engines fueled by coal. Manufacturing was focused in large mills or factories where many workers specialized in producing just one component, which was then assembled. This process resulted in abundant and cheap products.

During this period, industries were typically located near:

• Mining regions or other sources of energy (coal).
• Ports, cities, or train stations.

These factories created significant pollution, which explains why the area in England where the revolution started was historically known as "The Black Country."

The Second Industrial Revolution (
