Fouquet appeared eager to succeed Mazarin and Richelieu in assuming power, and he indiscreetly purchased and privately fortified the remote island of Belle Île. These acts sealed his doom. Fouquet was charged with embezzlement. The Parlement found him guilty and sentenced him to exile. However, Louis altered the sentence to life-imprisonment and abolished Fouquet's post.
