In 1925, the then Grand Master of the Order, Fra’ Galeazzo von Thun und Hohenstein, appointed Count Jenő Karátsonyi, who had been a member of the Oder since 1900 in the Austrian-Bohemian Grand Priorate, as Ambassador Extraordinary to Hungary. It was Jenő Karátsonyi who paved the way for the Order of Malta to authorise the creation of a Hungarian national association in 1928.

The centenary of the presentation of Count Jenő Karátsonyi’s credentials on 8th April 1925 was celebrated by the Hungarian Order of Malta, at the invitation of H.E. Ambassador Dr. Heinz Anton Hafner, on 10th April at the Church of the Holy Name of the Virgin Mary in Solymár, where Count Jenő Karátsonyi is buried. The solemn Mass was celebrated by Archbishop Michael W. Banach, Apostolic Nuncio, Conventual Honorary Chaplain Grand Cross. Among those present were former Ambassadors of the Order to Hungary HRH Michael Habsburg-Lothringen and Imre Ugron, the  President of the Hungarian Association of Knights of Malta Kristóf Szabadhegÿ, the President of the Hungarian Charity Service of the Order of Malta Péter Szabadhegÿ, as well as former President of the Republic Dr. Pál Schmitt, the Mayor of Solymár Mr. Peter Zlinszky, and numerous members of the Order.
