Age of Exploration & Enlightenment: Revolution and Reform
Geographical Discoveries
Driven by the search for a route to India and the pursuit of raw materials, luxury goods, and precious metals, the Spanish and Portuguese spearheaded exploration along the African coast. Inventions like the astrolabe, the compass, and safer ships emboldened them to venture farther. Key events include the discovery of America in 1492, the arrival in India via the African coast in 1498, and Magellan and El Cano’s circumnavigation of the globe (1519-1522), proving the Earth’

Geography of Spain
Latitude and Climate Zones
Spain’s location in the Northern Hemisphere’s temperate zone influences its climate, resulting in diverse weather patterns. The Canary Islands, closer to the intertropical zone, experience less contrast. The peninsula’s position between two large bodies of water and two continents makes it a crossroads of varied air masses.
Influence of the Sea and Relief
The sea’s influence on the peninsula is limited due to its narrowness, indented coastline, and mountain

1. The Problem of Freedom
Freedom is the right of every person to choose. However, are people born with total freedom? The answer is no. A person born in Africa does not have the same opportunities as a person born in Europe. A child whose parents are poor does not have the same opportunities as a child whose parents are rich. Furthermore, from birth, we are guided by laws we cannot break. Therefore, we do not have total freedom.

Determinism argues that humans are not free, but determined

Human Biology
Circulatory System
Arteries
Structure: Arteries have thick, slightly elastic walls to withstand high pressure from the heart’s pumping action.
Function: Arteries carry oxygenated, nutrient-rich blood away from the heart. Muscle contractions in artery walls regulate blood flow to organs.
Veins
Structure: Veins have thinner walls and one-way valves to prevent backflow.
Function: Veins return deoxygenated blood carrying cellular waste to the heart. Muscle contractions also control blood volume.

Nervous and Hormonal Coordination
Related Systems
Nervous System: Uses quick nervous impulses.
Endocrine System: Uses slow chemical messengers called hormones.
The nervous system acts first, activating the sympathetic nervous system in emergency situations. The parasympathetic system returns the body to normal.
The endocrine system secretes adrenaline (which stimulates the transfer of glycogen to glucose).
Sympathetic System
Inhibits unnecessary organs (like digestion) to allow for escape. Stimulates the

The Beginning of the Middle Ages
The End of the Roman Empire
Germanic peoples, who lived in villages and practiced pastoralism, inhabited the north of the Roman Empire. The Romans called them barbarians (foreigners), believing they were less civilized.
From the third century, these Germanic peoples began to enter Roman lands, sometimes peacefully and other times violently.
In 395, the Roman Emperor Theodosius divided the empire between his sons Honorius (West) and Arcadius (East).
The problems continued,

Short Questions
Causes of the Spanish Decline in the 17th Century
The Spanish Crown’s decline during the 17th-century European crisis was particularly rapid, especially in Castile. The main causes include:
- Policy: The Habsburg empire’s policies were financed by Castilian resources and American precious metals. Constant wars led to tax increases in an already overburdened Castile and increased borrowing. From 1621, the flow of American silver decreased due to depleted mines and piracy, forcing the

1.1 Hominization in the Iberian Peninsula
The humanization process in the Iberian Peninsula reflects the expansion of hominids from Africa to Asia and Europe. The Sierra de Atapuerca findings are significant, revealing the oldest remains in Western Europe. These include Homo antecessor (circa 800,000 years old) and Homo heidelbergensis (350,000 years old). Later stages include Homo sapiens neanderthalensis (100,000 years old) and Homo sapiens sapiens (40,000 years old)
