Data

A recoding of the PRIO/Uppsala Armed Conflicts Data Set to identify ethnic and secessionist conflicts. The Ethnic Armed Conflict dataset is compatible with the EPR Version 3 dataset and is integrated in the EPR stata files.

​

• Excel file

Contains two main datasets to explore the relationship between international wars and state building. One has information on 19 polities in 50-year intervals with gold gram taxation per capita as the outcome, from 1500-1900. The other dataset contains 120 countries with yearly observations from ca. 1860 to 2000 and has the government share of GDP as the outcome.

• ​Do-file to replicate Feinstein and Wimmer 2023 (RTX)

 

This is the replication dataset for Feinstein and Wimmer. 2023. “Consent and legitimacy. A revised bellicose theory of state building with evidence from around the world, 1500-2000”, in World Politics 75(1): 188-232.

This dataset combines representative survey data from 123 countries around the world and records responses to an identical question: "How proud are you to be of XY nationality"? The dataset also contains information, for a reduced sample of 64 countries, on the ethnic background of individuals, using EPR's group list and power status variables.

• Do-file to replicate Wimmer 2017 (RTX)

 

This is the replication dataset for Wimmer. “Power and pride. National identity and ethnopolitical inequality around the world", in World Politics 69(4):605-639, 2017.

Identifies the location and purpose of all 464 major wars since 1816, expanding substantially on previous efforts by including wars fought in all polities, including pre-independent kingdoms and empires. The data complements standard war datasets that characterize wars only by the state participants that fight them. Compatible with the From Empire to Nation-state dataset.

The dataset and coding rules are described in Wimmer and Min. “The location and purpose of wars around the world, 1816-2001", in International Interactions 35(4):390-417, 2009. 

Contains variables to explain the the spread of romantic nationalism in Europe's long 19th century, including the city and year when a work of romantic nationalism appeared, distance to towns with universities or newspaper printing, the nature of the polity to which a city belonged, distance to the next work of romantic nationalism on various transportation networks, etc. It covers 2200 European cities and decades from 1780 to 1920.

Ethnic Power Relations (EPR) Version 3 identifies all politically relevant ethnic groups and their access to state power in every country of the world from 1946 to 2010. It includes annual data on almost 800 groups and codes the degree to which their representatives hold executive-level state power — from total control of the government to overt political discrimination. Version 3 includes a new coding of type of ethnic marker distinguishing group members (religion, language, race, etc.). The last update of Version 3 occured on Dec 31 2014.

Contains variables indicating economic, political, and cultural modernization processes on the world's territories before they transition to the nation-state, the presence of nationalist organizations, wars, dependency from imperal centers, the power of these centers, the years in which a territory transitions to the nation-state, etc. It covers 140 territories (in their post-independence geographic extension) and years from 1816 onward.

This dataset contains survey data, including the results of an experiment, from 22 countries around the world. The experiment forced respondents to choose between fictions profiles of immigrants who applied for a permanent residence permit in their country.
