Though, like various European powers, earlier popes recruited Swiss mercenaries as part of an army, the Pontifical Swiss Guard was founded by Pope Julius II on 22 January 1506 as the personal bodyguards of the pope and continues to fulfill that function. It is listed in the ''Annuario Pontificio'' under "Holy See", not under "State of Vatican City". At the end of 2005, the Guard had 134 members. Recruitment is arranged by a special agreement between the Holy See and Switzerland. All recruits must be Catholic, unmarried males with Swiss citizenship who have completed their basic training with the Swiss Armed Forces with certificates of good conduct, be between the ages of 19 and 30, and be at least 175 cm (5 ft 9 in) in height. Members are armed with small arms and the traditional halberd (also called the Swiss voulge), and trained in bodyguarding tactics.
