Research Guide

What is Twelfth-Century Crusades?

Twelfth-Century Crusades refer to the Second Crusade (1147-1149) and Third Crusade (1189-1192), including Saladin's 1187 conquest of Jerusalem, analyzed through Latin, Arabic, and Byzantine primary sources.

This subtopic covers military campaigns, Frankish-Muslim alliances, and Crusader strongholds from 1147 to 1192. Key works include Abulafia (2011, 50 citations) on Frankish presence in the Eastern Mediterranean and Reston (2001, 22 citations) on Richard the Lionheart and Saladin. Over 200 papers address tactics, logistics, and leadership in this period.

Key Challenges

Why It Matters

Twelfth-Century Crusades marked the shift from Crusader dominance to Muslim reconquest, altering Mediterranean trade and pilgrimage routes (Abulafia 2011). Saladin's victory at Hattin in 1187 ended Latin control of Jerusalem, influencing Frankish-Muslim diplomacy (Köhler and Holt 2013). These events shaped Norman Sicily's multicultural governance (Metcalfe 2002) and military architecture like Belmont Castle (Harper and Pringle 2001).

Key Research Challenges

Reconciling Latin-Arabic Sources

Historians face discrepancies between Latin chronicles and Arabic accounts of battles like Hattin. Asbridge (2013) analyzes Saladin-Richard negotiations, highlighting biased narratives. Primary source synthesis requires cross-verification across languages.

Archaeological Site Dating

Excavations like Belmont Castle demand precise 12th-century attribution amid layered occupations. Harper and Pringle (2001) detail stratigraphic challenges in Crusader strongholds. Pottery and coin evidence often conflicts with textual records.

Quantifying Diplomatic Alliances

Tracking Frankish-Muslim treaties lacks comprehensive databases, complicating network analysis. Köhler and Holt (2013) catalog alliances but note incomplete records. Measuring treaty impacts on military outcomes remains qualitative.
