European Alliances & Alignments (1528-1648) V1.0

The datasets identify a list of key actors in the European sphere from 1528 to 1648 and introduce two ways of tracking diplomatic shifts in this era. The Formal Military Alliances and Political Settlements dataset (FMAPS) lists all formal treaties and agreements reached between major actors in the European sphere that codified a form of alliance among them--and for which a start and end year could be identified. The Alignments During Armed Conflicts dataset (ADACS) lists parties’ alignments during the period’s major armed conflicts. Both datasets were compiled through review of available literature about diplomatic ententes and armed conflicts throughout the period from 1528 to 1648. The ADACS and FMAPS datasets are presented in both a 'raw' format that lists each instance of an alliance or alignment, and a 'dyads' format that lists each instance of an alliance or alignment between two parties for each year during which it was active.
