From territorial claims to identity claims: The Issue Correlates of War (ICOW) Project

Abstract

The Issue Correlates of War (ICOW) research project began nearly 20 years ago by collecting data on territorial claims in South America. Since then, the ICOW territorial claims dataset has expanded to cover the entire world, while ICOW has collected new data on river claims and maritime claims and is beginning a new project on identity claims. This article discusses the development and expansion of ICOW data, illustrating how the additional datasets offer important new information and open up new avenues for scholarship.
