In 1607 and 1613, Bishop Woyna declared St. Casimir patron saint of Lithuania ("Patronus principalis Lithuaniae"). The issue of a universal St. Casimir's feast was not forgotten and in 1620 Bishop Eustachy Wołłowicz petitioned Pope Paul V to add Casimir to the Roman Breviary and Roman Missal. This time the Sacred Congregation of Rites granted the request in March 1621 and added his feast "sub ritu semiduplici". In March 1636, Pope Urban VIII allowed the celebration of the feast of St. Casimir with an octave ("duplex cum octava") in the Diocese of Vilnius and the Grand Duchy of Lithuania. That is equivalent of proclaiming St. Casimir as the patron saint of Lithuania. On 28 September 1652, Pope Innocent X allowed a fest of transfer of relics of St. Casimir on a Sunday following the Assumption of Mary. On 11 June 1948, when many Lithuanians were displaced war refugees, Pope Pius XII named Saint Casimir the special patron of Lithuanian youth.
