The paper describes the process of acquisition, up-translation, encoding, and annotation of the collection of the parliamentary debates from the Assembly of the Republic of Slovenia from 1990-1992, covering the period before, during, and after Slovenia became an independent country in 1991. The entire collection, comprising 232 sessions, 58,813 speeches and 10.8 million words was uniformly encoded in accordance with the Text Encoding Initiative (TEI) Guidelines, using the TEI module for drama texts. The corpus contains extensive meta-data about the speakers, a typology of sessions etc. and structural and editorial annotations. The corpus was also converted to use the spoken corpus module of TEI, and from this encoding automatically part-of-speech tagged and lemmatised. The corpus is maintained on GitHub and its major versions archived in the CLARIN.SI repository and available for analysis under its KonText and noSketchEngine concordancers, offering an invaluable resource for historians studying this watershed period of Slovenian history.
