This paper argues that rulers may strengthen legal institutions during political crises to secure support and funds. Using newly compiled data on 12th-century English common law operations, the author examines changes following Richard I's kidnap in 1192. Analyses show the catastrophe led to increased Royal Court activity initially concentrated in vulnerable regions. This short-term effect appears persistent into later periods and eventually spread nationwide. Evidence from court funding shifts between 1184-1203 suggests crises can permanently enhance legal system capacity.

Findings have broad implications for understanding common law development and the political economy of legal systems generally.
