CShapes Dataset of Historical Country Boundaries
CShapes is a dataset of country boundaries, incorporating changes in the period 1946-2015. The list of states is compatible with the "Correlates of War" system membership list, version 2011.1. The dataset provides information about the core territories of the given states, and excludes colonies and other dependent territories. The changing boundaries of the international system are represented in the dataset by coding a "lifetime" for each polygon, i.e. a start and end date between which the polygon is valid. Version: 0.6 (November 30, 2016).
