He was a capable administrator who built the first sewers in Paris, and strengthened the city's fortifications.
During the course of disturbances, in Paris, after the death of Charles V in 1380, he arrested citizens who had harassed the city's Jews.
For this, he was placed on trial, and a variety of trumped-up charges were brought against him, including heresy, sodomy, and extortion.
However, he was a strong supporter of Philip the Bold, Duke of Burgundy, who was able to prevent him from being executed.
In subsequent disturbances in Paris, he was released by a mob who were rioting against excessive taxation, and sought his support.
