Primož Trubar or Primus Truber[nb 2] (pronunciationⓘ) (1508[nb 1] – 28 June 1586)[1] was a Slovene Protestant Reformer of the Lutheran tradition, mostly known as the author of the first Slovene language printed book,[2] the founder and the first superintendent of the Protestant Church of the Duchy of Carniola, and for consolidating the Slovenian language.

Trubar introduced The Reformation in Slovenia, leading the Austrian Habsburgs to wage the Counter-Reformation, which a small Protestant community survived.

From there he went to Trieste under the tutorship of the Roman Catholic bishop Pietro Bonomo, where he got in touch with the Humanist writers, in particular Erasmus of Rotterdam.

[6] It was the language of Ljubljana that Trubar took as a foundation of what later became standard Slovene, with small addition of his native speech, that is Lower Carniolan dialect.

In 1550, while a Protestant preacher in Rothenburg, he wrote the first two books in Slovene, Catechismus and Abecedarium, which were then printed that year in Schwäbisch Hall by Peter Frentz.

It is one of the oldest roads in the city, first mentioned in 1802, and starts in Prešernov trg (Prešeren Square), named after Slovenia's national poet.

[15][16][17] An exhibition dedicated to the life and work of Primož Trubar, and the achievements of the Slovene Reformation Movement was on display at the National Museum of Slovenia from 6 March to 31 December 2008.
