Parliamentary Deployment Votes 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 datasets to include additional countries and to update the datasets regularly.

Version 3

Version 3 of the database (V3, July 2021) contains data on 1,022 votes in plenaries and 5,540 party votes for the period between August 1990 and December 2019 in Australia, Belgium, Canada, Croatia, the Czech Republic, Denmark, Finland, France, Germany, Ireland, Italy, Japan, Lithuania, the Netherlands, Romania, Slovakia, South Korea, Spain, Turkey, the United Kingdom and the United States of America.
