The emblem of Guatemala was adopted in 1871. The emblem was designed by Swiss artist and engraver Johan-Baptist Frener, who lived in Guatemala from 1854 until his death in 1897. The current Guatemalan emblem was created according to the Executive Decree number 33 of 18 November 1871 (Decreto No. 33 del 18 de noviembre de 1871) issued by the president General Miguel García Granados. According to the decree, "The arms of the republic will be: a shield with two rifles and two swords crossed with a wreath of laurel on a field of light blue. The middle will harbor a scroll of parchment with the words "Liberty 15 of September of 1821" in gold and in the upper part a Quetzal as the symbol of national independence and autonomy." The shield which is mentioned in the description above is never used and the emblem is therefore, without the shield, by heraldic standards, de facto no coat of arms.
