Territorial Change (v5)
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 1816-2014. 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 21, 2015, we released the fifth version of this data set (that covers 1816-2014). This is an update of the earlier territorial change data set that ended in 2008. In version 5, three new cases were added
In any papers or publications that utilize this data set, users are asked to give the version number and cite the article of record for the data set, as follows:
