Spain’s history is defined by a single, extraordinary narrative: the Reconquista — the 750-year effort to reclaim the Iberian Peninsula from Islamic rule. Beginning with a small band of Christian resisters in the mountains of Asturias in AD 718, this story did not conclude until the fall of Granada in 1492. What makes Spain a fascinating case for the 270-year cycle framework is that this civilizational narrative aligns with the cycle’s turning points with remarkable precision — an average error of just 6.4 years across 15 turning points, with four perfect zero-error matches. For readers unfamiliar with Spanish history, this analysis also serves as an introduction to one of Europe’s most dramatic civilizational stories.
【Triple Cycle Analysis】Spanish Civilization — Macro-Cycle Edition
AD 718 to AD 2068 — 5 Chapters, a 1,350-Year Grid
Starting Point: AD 718 (Battle of Covadonga · Pelayo · Founding of the Kingdom of Asturias)
Confirmed average error: 6.4 years (15 turning points) — precision comparable to the Egypt edition
The Significance of the Starting Point — The Moment the Prototype of “Spain” Was Born
In AD 718, Pelayo created the nucleus of resistance against Islamic domination of the Iberian Peninsula at the Battle of Covadonga, founding the Kingdom of Asturias. This was not merely a military victory — it was the moment from which all of modern Spain’s identity draws its roots.

Master Blueprint — 5 Chapters, 1,350 Years
[table as in original]
Zero-error matches at 4 points: Battle of Covadonga (AD 718) · Black Death reaching Iberia (AD 1348) · Start of the Thirty Years’ War (AD 1618) · Spanish Constitution (AD 1978) — four turning points with perfect alignment. “The 270-year cycle functions with high precision in Spanish civilization through to the modern era.”
Detailed Analysis of Each Chapter
Chapter 1 (AD 718–988) — Dawn of the Reconquista
[table as in original]
“The greatest humiliation generates the greatest counterattack” pattern
Al-Mansur’s sacking of Santiago de Compostela at the endpoint (AD 997) — the insult to the greatest holy site of the Christian world — became the driving force of the “acceleration of the Reconquista” in the next 270 years.
Chapter 2 (AD 988–1258) — Acceleration of the Reconquista
[table as in original]
“Northern Unification” vs. “Southern Fragmentation”
In AD 1031, the Caliphate of Córdoba collapsed and Andalusia fragmented into small kingdoms (Taifas). The dynamic of “unified North” vs. “fragmented South” accelerated the Reconquista. The unification of Castile and León by Alfonso VI (1072) led directly to the fall of Toledo (1085).
The León Cortes (1188) — cited as one of the world’s earliest parliaments — emerged during this period, reflecting how the pressure of the Reconquista simultaneously drove political innovation.
Chapter 3 (AD 1258–1528) — The Road to a Unified Kingdom
[table as in original]
The most important discovery of Chapter 3: The Black Death (1348) — zero-year error
One-third of the population died and social structures were transformed. The dual nature of Spain — “land Reconquista” and “maritime expansion” proceeding simultaneously — was established in this chapter. The year 1492 is the midpoint of this chapter — the “fateful year” in which the Fall of Granada, Columbus reaching the Americas, and the expulsion of the Jews all occurred in the same year.
Chapter 4 (AD 1528–1798) — From the Golden Age to the End of Hegemony
[table as in original]
The Thirty Years’ War (1618) — zero-year error · “The peak of hegemony and the beginning of decline”
Spain entered the war as the leading power of the Habsburg Empire, winning but exhausting itself. The word “guerrilla” is Spanish — resistance to Napoleon gave birth to guerrilla warfare as a new form of combat.
Chapter 5 (AD 1798–2068) — The Search for a Modern State
[table as in original]
The Spanish Constitution (1978) — zero-year error · “The miracle of democracy”
The completion of the democratic transition after the Franco dictatorship (1939–1975). Known as “La Transición,” this peaceful regime change attracted worldwide attention. It aligns perfectly with the 2nd node turning point of the 270-year cycle.

★ The Great Transformation of 2068 — Questions Spain Faces
Heading toward the endpoint of the 270-year cycle (2068), Spain faces several fundamental questions:
– The Catalonia question — “Is Spain one country, or a union of multiple peoples?”
– Position within the EU — “Is Spain the leading power of Mediterranean Southern Europe, or a periphery of a North European-led EU?”
– Demographic change — transformation of social structures through increased immigration and declining birth rates
– Economic model transformation — the shift from tourism dependence to knowledge and technology industries
“After the 1,350-year story of the Reconquista reaches its conclusion, how will Spain write the next story?” — This is the question of the 2068 turning point.
Conclusion
“The story that began at Covadonga was completed as democracy over 1,350 years.”
The 270-year cycle starting from AD 718 captured 15 turning points in Spanish history with an average error of 6.4 years.
Four zero-error matches — this precision is evidence that “the cycle functions in Spanish civilization too.”
And the next great transformation is 2068 — 42 years from now.
