 of the political structures of 144 countries worldwide (428 polities) 
 in the period 1800-1971. One of four distinct but related datasets 
 developed by Robert Gurr and his associates at Princeton University 
 and Northwestern University to test hypotheses about the causes of 
 conflict within contemporary nations and the correlates of 
 institutional change, this study probes why some political 
 institutions perform well and persist in response to challenges and 
 crises while others change abruptly. Operational conceptualization
 of the study is provided with the description of salient
 characteristics of political systems in terms of the dimensions 
 of authority patterns. Included are indicators of dimensions of
 authority, such as the openness of recruitment, decision constraints,
 participation, directiveness, and complexity, the degree to which 
 each polity was autocratic, democratic, and anocratic, and the 
 dichotomous indicator of coherence of a polity as consistently 
 democratic. Additional data provide information on the circumstances 
 of the birth and death of a polity, including the character of the 
 polity and reasons for its termination. Three related studies focus 
 on civil conflicts in polities: CONFLICT AND SOCIETY (ICPSR 7452), 
 CIVIL STRIFE EVENTS, 1955-1970 (ICPSR 7531), and CIVIL STRIFE CONFLICT 
MAGNITUDES, 1955-1970 (ICPSR 7485).</div>
