[2] From 1850 to 1873, the elder Coroianu, a participant in the Blaj Assembly, served at Șimleu Silvaniei, where he was active in cultural affairs.
That year, he defended Vasile Lucaciu in court at Satu Mare, securing an acquittal.
During the collective trial held at Cluj two years later, Coroianu tenaciously defended himself, even continuing to stand and set forth his argument after being ordered by the bench to remain silent.
Found guilty of conspiracy against the public order, he was sentenced to two years and eight months at hard labor and imprisoned at Szeged.
[1] He was an active participant in the preparation and proceedings of the Great National Assembly at Alba Iulia that proclaimed the union of Transylvania with Romania in December 1918.
