Lustration is a process used to remove individuals from positions of power or influence, particularly those who were involved in oppressive regimes or unethical practices. It often occurs in post-conflict societies or after significant political changes, aiming to promote accountability and restore public trust. This practice can involve legal measures, such as vetting procedures, to assess the past actions of officials. Countries like Czech Republic and Poland have implemented lustration laws to address the legacy of communism and ensure that former collaborators with oppressive systems do not hold public office.
