In the 19th and 20th centuries, various Byzantine-Rite Catholics from Austria-Hungary arrived in the United States, particularly in coal mining towns.
Members of the predominant Latin Church Catholic hierarchy were sometimes disturbed by what they saw as the innovation, for the United States, of a married Catholic clergy.
At their persistent request, the Sacred Congregation for the Propagation of the Faith applied, on 1 May 1897, to the United States rules already set out in a letter of 2 May 1890 to François-Marie-Benjamin Richard, the Archbishop of Paris.
These rules stated that only celibates and widowed priests coming without their children should be permitted in the United States.
The dissatisfaction of many Ruthenian Catholics had already given rise to some groups placing themselves under the jurisdiction of what is today the Orthodox Church in America (at that time a mission of the Russian Orthodox Church).
The leader of this movement was the widowed Ruthenian Catholic priest Alexis Toth, whose mistreatment by Archbishop John Ireland of Saint Paul, Minnesota, led to Toth's transfer to Eastern Orthodoxy.
He brought with him many Ruthenian Catholics, around 20,000 by the time of his death with many who followed afterward, and was canonized a saint by the Orthodox Church in America in 1996.

The situation with Alexis Toth and the Latin Catholic bishops highlighted the need for American Eastern Catholics to have their own bishop.
Pope Pius X appointed the Ukrainian bishop Soter Ortynsky in 1907 as bishop for all Slavic Eastern Catholics of the Byzantine rite in America.
For this period the Ruthenian Byzantine Catholics were united to the Ukrainian Greek Catholics in the same eparchy.
Ethnic tensions flared due to cultural differences (mostly of a political nature) between Ukrainians who came from Austrian-ruled Galicia and the Rusyns and other Byzantine Catholics who came from the Kingdom of Hungary.
This caused Rome to split the groups after Ortynsky's death by creating a new separate eparchy especially for Byzantine Catholics coming from Hungary - mostly Rusyns but also ethnic Hungarians, Slovaks, Croats and Serbs.
The Rusyn priest Basil Takach was appointed and ordained in Rome on his way to America as the new eparchy's bishop.
Bishop Takach is considered the first bishop of Ruthenian Catholics in America, and his appointment as the official founding of the Byzantine Catholic Metropolitan Church of Pittsburgh.

Clerical celibacy of American Eastern Catholics was restated with special reference to the Byzantine/Ruthenian Church by the 1 March 1929 decree Cum data fuerit, which was renewed for a further 10 years in 1939.
Due to this and other similar factors, 37 Ruthenian parishes transferred themselves into the jurisdiction of the Greek Orthodox Ecumenical Patriarch in 1938, creating the American Carpatho-Russian Orthodox Diocese.


Relations with the Latin Church Catholic hierarchy have improved, especially since the Second Vatican Council, at which the Ruthenian Church influenced decisions regarding using the vernacular (i.e. the language of the people) in the liturgy.
In its decree Orientalium Ecclesiarum, the Second Vatican Council declared:
 "The Catholic Church holds in high esteem the institutions, liturgical rites, ecclesiastical traditions and the established standards of the Christian life of the Eastern Churches, for in them, distinguished as they are for their venerable antiquity, there remains conspicuous the tradition that has been handed down from the Apostles through the Fathers and that forms part of the divinely revealed and undivided heritage of the universal Church."

The Second Vatican Council urged the Eastern Rite Churches to eliminate liturgical Latinization and to strengthen their Eastern Christian identity.
In June 1999 the Council of Hierarchs of the Byzantine Metropolitan Church Sui Iuris of Pittsburgh U.S.A. promulgated the norms of particular law to govern itself.
