From Empire to Nation-State Replication Data: Territorial Data, 1816-2001

<p>This is the replication dataset for Wimmer and Min. “From empire to nation-state: Explaining war in the modern world, 1816-2001”, American Sociological Review 71(6):867-897, 2006. The From Empire to Nation-State dataset is a territory-year dataset spanning 150 territories over the 186-year period between 1816 and 2001. Traditional country-year datasets typically include only countries after they have become independent or recognized members of the nation-state system. This project collects data on territories both prior to and after they became independent states. The dataset is made up of 28,162 territory-year observations, including a large number of territory-year observations in periods prior to nation-statehood. Takes fixed geographical territories instead of countries as units of analysis, enabling the tracing of a territory’s political and economic development before and after independence from 1816 to 2001.</p>
