Archbishopric of Riga
The Archbishopric of Riga (Latin: Archiepiscopatus Rigensis, Low German: Erzbisdom Riga) was an archbishopric in Medieval Livonia, a subject to the Holy See.The see was restored as a diocese of the Catholic Church in 1918 and raised into an archdiocese in 1923.A new Bishopric of Livonia was established in Latgalia in 1621 during the Inflanty Voivodeship of the Polish–Lithuanian Commonwealth.The Archbishops of Riga were innovators in the field of minting currency, reviving techniques abandoned since the collapse of Rome.The names of individual archbishops after 1418, as well as the years of their respective reigns, are stamped on Livonian pennies excavated at archaeological sites.
