According to 2 Kings 8:16, Jehoram became king of Judah in the fifth year of Jehoram of Israel, when his father Jehoshaphat was (still) king of Judah, indicating a co-regency. Jehoram took the throne at the age of 32 and reigned for 8 years. To secure his position Jehoram killed his six brothers.[3] (2 Chronicles 21:2–4)
