Mapping The International System, 1886-2017: The CShapes 2.0 Dataset

Kristian Skrede Gleditsch
Journal of Peace Research (Under Review).
This article introduces CShapes 2.0, a GIS dataset that maps the borders of states and dependent territories from 1886 through 2019. CShapes 2.0 builds on the existing CShapes dataset and extends it in two main ways. First, it extends temporal coverage from 1946 back to the year 1886, after the Berlin Conference on the partition of Africa. Second, the new data are no longer restricted only to independent state borders, but also map the borders of colonies and other dependencies, thus providing near complete global coverage of territorial units throughout recent history. This article explains the coding procedure, provides a set of descriptive statistics and presents two illustrative applications of the new dataset.
