Introducing the International Treaty Ratification Votes Database

This research note introduces the International Treaty Ratification Votes Database, which covers more than 6,000 votes on the ratification of international treaties in Canada, Finland, France, Germany, Italy, Slovakia, Spain, Turkey, the United Kingdom, and the United States between 1990 and 2019. In addition, the database presents data on the voting behavior of ninety parties in eight of these countries, resulting in more than 11,000 party observations. The research note presents the two datasets with their two units of analysis, the parliamentary and the party level, and describes the main variables, reaching from descriptive vote and cabinet data to issue areas, comparative party family classifications, and actual voting records. Furthermore, we suggest avenues for using the data for future research on the domestic politics of foreign policy: Our data can be used to study patterns in the politicization of international treaties and organizations, ratification delays, legislative-executive relations, the party politics of foreign policy making, and the crisis of the liberal international order.
