The Second Industrial Revolution (1870-1914)

Key Developments and Impacts

The Second Industrial Revolution, spanning from 1870 to 1914, marked a period of unprecedented growth and transformation. This era saw significant advancements that fueled a dramatic increase in production:

• New Sources of Finance: The emergence of institutions like banks, joint-stock companies, and stock exchanges revolutionized capital formation.
• Innovative Business Structures: New organizational models such as cartels, trusts, and holding companies reshaped industries.
• Technological Breakthroughs: Continuous technological advancements drove efficiency and innovation.
• New Energy Sources: The widespread adoption of oil and electricity powered new machinery and industries.
• Emergence

The Problems Affecting Relief and Soil

Alterations Made to the Relief

Changes to the relief are caused by mines and quarries as well as by transport infrastructure. The landscape is marred, and locations of geological importance are destroyed.

This problem affects natural environments and is more common in poor countries, where mining provides the foundation for their economy.

Alterations Made to the Soil

Two main problems are erosion and pollution.

Erosion and Desertification

Erosion of the soil is due to deforestation and inappropriate agricultural and livestock farming methods. In developed countries, intensive and single-crop farming are common; in the poorest countries, it is due to not leaving farming land fallow and excessive grazing of pasture...

Ancient Iberia

Celts

Celtic peoples, an Indo-European group, migrated to the Iberian Peninsula between the 10th and 5th centuries BC. Organized into clans and tribes, their hierarchical society placed warriors at the top. These cattle farmers resided in fortified hilltop villages known as castros, which were largely self-sufficient due to limited trade. Their dwellings were typically rounded, and they practiced polytheism and cremation in designated necropolis.

Celtiberians

Representing a more developed Celtic group due to Iberian influence, the Celtiberians inhabited larger settlements called oppida and possessed a written language.

Iberians

Indigenous to the Iberian Peninsula, Iberians were influenced by colonizers such as the Phoenicians and... Continue reading "Ancient Iberia: Celts, Iberians, and Roman Conquest" »

The Crown of Castile (1230–1492)

The Crown of Castile began in 1230 when Fernando III inherited the Kingdom of Castile and the Kingdom of León, uniting them under a single crown.

Institutional Structure of Castile

The territories were governed by shared institutions and laws. The monarch held significant power, able to declare war, make laws, and act as a judge. Key institutions included:

• Parliament (Cortes): Composed of noblemen, clergy, and representatives from cities.
• Royal Council: Advised the King on governance and policy.
• High Court (Audiencia): Held supreme judicial authority.

Municipal Government: The Council was the main governing body, while the Chief Magistrate represented the King in the cities.

Problems Affecting Water Sources and the Atmosphere

Alterations to Water Sources

Overexploitation of Water Resources

Overexploitation is the excessive consumption of freshwater as a result of agrarian, urban, and industrial usage. River discharge levels fall, as do lake and aquifer water levels. This problem primarily affects semi-arid environments.

Water Pollution

Pollution affects both freshwater and saltwater sources. It is caused by chemical products used in agriculture, industrial and urban waste, and accidents involving oil tankers, which give rise to oil slicks. The quality of water supplies is reduced, and aquatic plants and animals disappear.

Affected water sources include sections of rivers and coasts near industrial and urban areas, enclosed... Continue reading "Water and Air Degradation: Global Environmental Impacts" »

The Trans-Saharan Trade Network

The Trans-Saharan trade route was a vital commercial artery, connecting the Mediterranean coast of North Africa with West African nations from the 8th to the late 16th century. Following the 7th century, Arab expansion into North Africa led to their control over Saharan trade routes. The period from the 8th to the 11th centuries marked the development of this trade, with its zenith occurring between the 11th and 16th centuries. Subsequently, the trade experienced a decline. The Sahara Desert's central location made it the primary conduit for this commerce, which was primarily conducted by caravans of camels.

Deforestation and Biodiversity Decline

Deforestation: Causes and Consequences

Deforestation is the removal of plant cover. It is caused by:

• The mass burning or felling of trees to transform land for agricultural, livestock farming, or residential uses.
• Supplying timber to industries.
• The building of infrastructure.
• The collecting of firewood.

As a result of deforestation:

• Levels of carbon dioxide increase.
• Humidity levels, along with water reserves, are diminished.
• Soil erosion increases due to the lack of protection and binding provided by vegetation.
• Animal and plant species become extinct due to the disappearance of natural habitats.

Damage to Woodlands and Jungles

Developed countries: Damage is most widespread in temperate and frigid woodland regions,... Continue reading "Deforestation's Impact on Biodiversity and Ecosystems" »
