One point of caution is that progress in democratization in fragile states are vulnerable. According to Samuels (2013), history has witnessed regime changes from democracy to autocracy during the periods of 1925-1945 Germany (1933) and 1960-1974 Brazil (1964), Chile (1973). What he identifies as domestic causes of regime change are also the factors to be mitigated through institutional design. Some of these factors are civic culture, class conflicts arising from the unequal distribution of economic gains and military identity. Some of the international causes are the foreign policy of superpowers, the degree of participation in multilateral institutions, the extent of globalization and supranational impact of religious institutions on domestic political institutions.
