.. and I'd add Hungary too: 12 September 2021, Budapest, Holy Mass - Pope Francis
]. It's a Roman rite Mass but there is an Eastern/Byzantine and Ecumenical presence. I grew up in a Hungarian Roman-rite parish (50s-60s) and one of my fondest recollections is of the "Hungarian," i.e. the Sunday High Mass: Right after it concluded the Hungarian National Anthem was sung. Appropriately, it is a prayer, and is even called the Hymn, Himnusz
]. The opening words are Isten, áldd meg a Magyart
(pronounced ma-jart), God bless the Hungarian-people
. So I checked the video and it was indeed sung at 1:45:55. For me, both because of its pious words, addressing its cultural heritage and religious devotion, and its noble melody, it ranks at the very top as a historically-Christian nation's anthem. During its singing, the video appropriately shows a replica of the "Crown of St. Stephan", Holy Crown of Hungary
]. As explained in the link, It has an interesting connection with the US:
At the end of the Second World War the crown jewels were recovered in Mattsee, Austria, on 4 May 1945 by the U.S. 86th Infantry Division. The crown jewels were transported to Western Europe and eventually given to the United States Army by the Hungarian Crown Guard for safekeeping from the Soviet Union. For much of the Cold War the crown was held at the United States Bullion Depository (Fort Knox, Kentucky) alongside the bulk of America's gold reserves and other priceless historical items. After undergoing extensive historical research to verify the crown as genuine, it was returned to Hungary by order of U.S. President Jimmy Carter on 6 January 1978.
Most current academic knowledge about Hungarian royal garments originates from this modern research. Following substantial U.S. political debate, the agreement to return the jewels contained many conditions to ensure the people of Hungary, rather than its Communist government, took possession of the jewels. The majority of the Hungarian-American population opposed the decision to return the crown. On January 6, 1978, US Secretary of State Cyrus Vance returned the Crown to Hungary in Budapest.
I remember the controversy about Pres. Carter's decision at the time but, thankfully, it has turned out well.
