[1] Following the World War II and the Soviet occupation of Hungary, the Benedictine Order has come under pressure by the new Communist-dominated and pro-Soviet governments.
Officially, he left Hungary for a few months to visit the Hungarian Benedictine monastic orders in the Latin American country.
While residing in Brazil, Kelemen participated in the election of Bernard Kälin, Abbot Primate of the Benedictine Confederation, where he tendered his resignation to the Holy See in September 1947.
[3] In February 1948, Sárközy was elected representative of all Hungarian monastic orders during the celebrations of the Year of Mary or Beata Virgo.
The State Protection Authority (ÁVH) interned and deported the Benedictine monks to Kalocsa, Szolnok and Tihany in June 1950, alongside the other monastic orders.
Accordingly, the Catholic Church recovered altogether eight secondary schools and the Hungarian state permitted the operation of three male and one female religious orders with limited number of monks and nuns, respectively.
Two days later, Sárközy wrote a letter to Cardinal Clemente Micara, then Prefect of the Sacred Congregation of Religious, in order to inform him on Kelemen's death and request action to fill the position.
Due to the extraordinary situation of church politics, Sárközy was appointed as Archabbot of Pannonhalma by Pope Pius XII on 28 March 1951, instead of the canonical election prescribed in the statutes.
