This project analyzes relations between governmental institutions and states’ engagement in conflict internationally during the period 1816-2002. Special emphasis is placed on temporal and spatial variation. The project has involved data collection and analysis of three institutional dimensions: 

1. type of electoral system, 
2. type of executive system and
3. type of federal system. 

Results suggest that there are institutional and spatial differences in states’ conflict involvement and urge caution when democratizing for peace.
