The dean of the College of Cardinals presides over the College of Cardinals in the Catholic Church, serving as primus inter pares. The position was established in the 12th century. He always holds the rank of a cardinal bishop and is assisted by a vice-dean. Both are elected by and from the cardinal bishops who are not Eastern Catholic patriarchs, with their election subject to papal confirmation. Except for presiding over the college, the dean and vice-dean have no power over the other cardinals. In the order of precedence in the Catholic Church, the dean and vice-dean, as the two most senior cardinals, are placed second and third, respectively, after the pope.
