Annual Polity scores have been plotted for each of the 167 countries currently covered by the Polity IV data series for the period 1946-2013 (trend graphs are also included with the Polity IV 2010 Country Reports). This version of the Polity Country Trend graphs display periods of "factionalism" and important Polity change events, including autocratic backsliding, executive auto-coup or autogolpe, revolution, collapse of central authority (state failure), and successful military coups. Click on the country of interest in the "Regimes by Type 2013" map directly below (or table following) to view that country's contemporary regime trend (click here for a explanatory guide to the Polity Country Trend graphs).
