Extended version of the 'Cabinet conflicts in Belgium (1979-2018)' dataset (doi:10.17632/2zt252t9gv.2). Data on conflicts in Belgian cabinets between 1979 and 2018 (central level), based on the manual coding of two data sources: political yearbooks (1979-2006; N=364 conflicts) and an extended coding of news agency articles (1995-2018; N=1090 conflicts). Includes an extensive description of each conflict and variables grasping their intensity, outcome (yearbook data), situations of doubt, and two variables grasping communal sides (absence/presence vs. detailed nature). The variables grasping the presence or absence of communal issues is now complemented with a new variable that distinguishes between different types of communal issues. Codebook and logbook available on demand.
