Charles V the Wise: Reconquest, Statecraft, and the Western Schism (1364-1380) · HIGH MIDDLE AGES
For Charles V, reconquest had to be politically justified. The opening came in Guyenne, where lords and towns challenged the Black Prince’s fiscal authority.
After costly Castilian campaigning, the Black Prince imposed new taxation (notably in January 1368). Many local elites judged it illegitimate, especially amid mercenary devastation.
When local redress failed, Gascon lords appealed to Charles V. By accepting jurisdiction, he reasserted feudal sovereignty and created a legal pathway against the Black Prince.
The monarchy used legal timing and political bargaining to gather support among Gascon elites before full military escalation.
By early 1369, fighting resumed locally, and at the top level Charles V moved toward formal confiscation of Aquitaine, converting legal argument into strategic war policy.
