Territorial Change, 1816-2018 (v6)
Overview
The territorial change dataset is the result of the effort to identify and code all territorial changes involving at least one nation-state (as defined by the Correlates of War project) for the period 1816-2018. The data are restricted to territorial changes that involve at least one recognized (by COW) nation-state. Both the nation states and the non-nation states involved in territorial changes are regarded as political entities. This dataset contains information on the entities involved, the gaining side, the losing side, the territory exchanged, as well as the type and date of the exchange.
On March 25, 2019 we released the sixth version of this data set (that covers 1816-2018). This is an update of the earlier territorial change data set that ended in 2014. Listed updates and new data are available in the zip file below.
