The Mapping Interstate Territorial Conflict (MITC) project consists of precise digital maps of regions that were the subject of interstate territorial disputes in the period 1947-2000. Disputes identified by Huth and Allee (2002) were rendered as polygons corresponding the regions of states' overlapping claims. Further information can be found in the codebook and the published paper describing these data, referenced below.
This polygon shapefile represents areas that were the subject of interstate territorial disputes between 1947 and 2000. The disputed areas referenced in this map were identified in 'The Democratic Peace and Territorial Conflict in the Twentieth Century' (Huth and Allee, 2002.) Each disputed region is rendered as a polygon encompassing the area of overlapping claims. Each region has a variable 'homeland,' indicating whether the area was ever part of a dispute involving homeland territory for both states. Each dispute is also assigned a precision code, from 1 to 5, where 1 represents the highest level of certainty and 5 represents the lowest level. The vast majority of claims represented in this dataset were bounded with relatively high precision. Research related to these data is described in 'Mapping Interstate Territorial Conflict: A New Data Set and Application.' An earlier version of this shapefile and other related information including annual data for dyads and direct dyads involved in disputes, as well as a file of the territorial disputes identified by Huth and Allee, can be found at: http://purl.stanford.edu/zc000fq4044.
