At that time the people of Slovenia got the first book in their language: Catechismus (1550), in which Trubar for the first time in history used the name Slovenians and established the Slovenian language as a standard language.
Dal nam je prvo tiskano knjigo v svojem jeziku (Katekizem, izšel je leta 1550) in nas v njej prvič v zgodovini poimenoval Slovenci.
