The Ja'chuq is a Klingon ceremony that is sometimes part of the Rite of Succession. The Ja'chuq was used in the ancient rite, and rarely used in modern times. However the Ja'chuq can still be used as part of the Rite if desired by the Arbiter of Succession. In the Ja'chuq the two strongest challengers would each have to, among other things list the battles they had won and the honor they had gained in the process – proving to the Klingon High Council why they were worthy to lead the Klingon people.
