Failure of Religious/Political Leadership

In class we discussed the failure of our religious/political leadership to heed Yirmiyahu's nevuot and to follow in the way of HaShem and Torah. Think of two other times in Jewish history (one from Tanach and one post-Tanach) when our religious/political leadership failed to serve as positive role models for the Jewish people. Give the time period, the location, the leader(s)and how they failed us. Do not use examples that are already posted by your classmates.
