Expert Analysis
Origins
Al-Hadi (born 764 CE, died 786 CE) was the fourth Abbasid caliph, son of Caliph al-Mahdi and the powerful Khayzuran. His early life was spent in the opulent courts of Baghdad, where he was groomed for leadership but overshadowed by his more capable brother Harun al-Rashid. John II of Castile (born 1405, died 1454) was the son of Henry III of Castile and Catherine of Lancaster. He became king at only one year old, leading to a long regency dominated by his uncles and later by his favorite, Álvaro de Luna. Both rulers inherited thrones at young ages and faced challenges from powerful relatives.
Rise to Power
Al-Hadi became caliph in 785 upon his father's death, but his accession was contested. His mother Khayzuran had wielded significant influence during al-Mahdi's reign, and Al-Hadi sought to reduce her power, leading to a rift. He also attempted to remove his brother Harun from the succession, provoking a crisis that ended with his sudden death in 786—likely murdered by his own mother or Harun's supporters. John II's rise was formal: he inherited the throne in 1406 but was controlled by regents until 1418. He then fell under the sway of Álvaro de Luna, who became Constable of Castile in 1423. John's reign was marked by constant power struggles with the nobility, but he never fully asserted independence. Unlike Al-Hadi, John II survived his conflicts for decades, but his authority was undermined by reliance on a favorite.
Leadership & Governance
Al-Hadi's leadership was confrontational. He attempted to centralize power by limiting his mother's influence and removing Harun, but his aggressive tactics alienated the court. His military score of 10.2 reflects his lack of major campaigns; his brief reign saw no significant conquests. Politically, he scored 30.7, indicating limited effectiveness. John II's political score was also 30.7, but his leadership style was passive. He delegated governance to Álvaro de Luna, who implemented reforms and strengthened royal authority through victories like the Battle of Olmedo (1445). However, John's inability to rule independently led to instability. His military score of 10.2 mirrors Al-Hadi's, as neither led armies personally. John's strategic score of 45.0 exceeded Al-Hadi's 54.8? Actually, John's strategy is 45.0, Al-Hadi's 54.8, so Al-Hadi had a slightly higher strategic score, possibly due to his attempts to secure succession.
Triumph & Tragedy
Al-Hadi's greatest triumph was briefly consolidating power after his father's death, but his greatest failure was his inability to manage family dynamics. He died under mysterious circumstances after only one year, scoring a total of 37.1. His legacy score of 34.2 reflects his obscurity. John II's triumph was the victory at Olmedo, which temporarily subdued the rebellious nobility. His tragedy was the execution of Álvaro de Luna in 1453, under pressure from his wife and nobles—a decision that weakened the crown. John's total score of 36.3 is slightly lower than Al-Hadi's 37.1, but his influence score of 46.3 matches Al-Hadi's, showing both left moderate footprints.
Character & Destiny
Al-Hadi was ambitious and assertive, but his authoritarian approach provoked opposition. His decision to challenge Harun and his mother proved fatal, as his death likely resulted from a palace coup. John II was indecisive and dependent, allowing favorites to rule. His character led to a reign of constant factionalism. Historical assessments note that Al-Hadi's potential was cut short, while John II's weakness defined his era. Both rulers scored 39.0 and 34.6 in leadership, respectively, with Al-Hadi slightly higher due to his active, albeit flawed, decision-making.
Legacy
Al-Hadi's legacy is minimal; he is remembered primarily as the caliph who preceded Harun al-Rashid, whose reign became a golden age. John II's legacy is more substantial: his reign saw the rise of Álvaro de Luna and the consolidation of noble power, leading to future conflicts. His legacy score of 37.5 edges Al-Hadi's 34.2, as Castile's political landscape was shaped by his choices.
Conclusion
Despite Al-Hadi's higher total score (37.1 vs. 36.3), John II of Castile had greater impact. Al-Hadi's reign was too brief to effect change, while John II's 48-year reign, though weak, allowed for the promotion of a powerful constable and set precedents for noble influence. John II's influence score of 46.3 and legacy of 37.5 indicate a more lasting, if negative, mark. Thus, John II of Castile had a greater historical impact.

How This Comparison Works
Algorithm
Each figure is scored on 6 dimensions (0—100 scale) based on structured historical data: Military (10%), Political (20%), Influence (20%), Legacy (20%), Leadership (15%), Strategy (15%). The weighted total produces the final ranking.
Data Sources
Scores are computed from structured sub-indicators in the database. Scale factors adjust for era (Ancient ×0.85, Modern ×1.0) and civilization size (Eastern ×1.05, Other ×0.80) to account for differences in population and military scale.
Maximum 3 Figures
Comparisons are limited to 2—3 figures to ensure readability and statistical meaningfulness.
Error Margins
±5 points per dimension — Sub-scores are derived from historical records with inherent uncertainty. Two figures within 5 points on a dimension should be considered roughly equivalent in that area.
Total Score Accuracy
±3 points overall — The weighted combination of 6 dimensions produces a total score with approximately ±3 points of uncertainty. Differences of less than 3 points are not statistically significant— the figures are effectively tied.
Known Limitations
- Historical records are incomplete and uneven across civilizations
- Figures from oral-tradition societies may be underrepresented
- Occupation labels can misclassify multi-role figures
- Scores measure capability and impact, not moral character
- Quantitative scoring is a comparison tool, not absolute truth
