In fact, the city's characteristic coffee culture was established and run for a long time in its early decades by Armenian merchants.

The very first documented coffee house in Vienna was opened on 17 January 1685, by Johannes Deodat (or Diodato, known in Armenian as Owanes Astouatzatur – Յովհաննէս Աստուածատուր – some sources claiming him to be Greek).

[2][3][4] In 1772–1774, the Austrian Empire annexed Galicia (see Austrian Partition, as part of the late-18th century Partitions of Poland) and especially the formerly Moldavian Voivodeship of Bukovina (see Treaty of Küçük Kaynarca; today a part of Ukraine), which at the time held the largest area contiguously settled by Armenians in Europe, and the Bukovian and Galician Armenians automatically became subjects to the Empire.

In 1775, Maria Theresa gave official permission to the Mechitarist Congregation of the Armenian Catholic Church to settle in the Habsburg Empire.

Although the monastic headquarters of the Mekhitarist Order founded by Mekhitar da Pietro(1676–1749), an Armenian Catholic monk is on the island of St. Lazarus in Venice (San Lazzaro Monastero Armeno in Italian), the Mechitarists have kept an important presence in Vienna since 1810.

Even much before, actually in 1775, Maria Theresa had already given the official permission to the Mechitarists congregation of the Armenian Catholic Church to settle in the Habsburg Empire and they had established in Trieste.

An association was formed for the propagation of good books worldwide to all Armenian communities, and a high-quality printing press that published average of six new works each year.
