In 1540 Ungnad had been appointed on the position of Captain General of Lower Austria (modern-day Slovenia), Croatia and other Habsburg estates.

[2] In 1555 he refused to execute anti-Protestant measures requested by Ferdinand I, resigned his position and opted for voluntary exile in Germany.

[8] Baron Ungnad was interested in Protestant proselytism propagated by Primož Trubar and attended the session of German theologians held in Tubingen in 1561.

[6] The books they printed at this press were planned to be used throughout the entire territory populated by South Slavs between the Soča River, the Black Sea,[9] and Constantinople.

[13] For this task, Trubar engaged Stjepan Konzul Istranin and Antun Dalmatin as translators for Croatian and Serbian.
