Our Data

Our data are freely available to scholars and a broader public interested in how political parties vote on military missions. Our aim is to extend the dataset to include additional countries and to update the dataset regularly.

Version 2(b)

Version #2 of the dataset (first published in May 2019, with votes included until December 2017; with slight corrections* in the party_vote file version #2b in November 2019) now covers 11 countries (Belgium, the Czech Republic, Denmark, Finland, France, Germany, Italy, Slovakia, Spain, the United Kingdom and the United States of America).

(* The changes are the following: The name of the Czech party TOP09 was misspelled in some lines. 10 votes of the Danish Centre Democrats (CD) were accidentally doubled and have been removed.)
