Unlike Artistotle's analysis, recent treatments of democratization identify
pathways and propose necessary conditions but fall short of specifying cau
se-effect relations. Democratization does not follow a single path, and is
unlikely to have universally applicable necessary or sufficient conditions.
A political process analysis of democratization defines it as movement tow
ard broad citizenship, equal citizenship, binding consultation of citizens,
and protection of citizens from arbitrary state action. High levels of all
four elements depend on a significant degree of state capacity. Democratiz
ation emerges from interacting changes in public politics, categorical ineq
uality, and networks of trust, which in turn depend on specifiable mechanis
ms of change in social relations. When the shocks of conquest, confrontatio
n, colonization, and revolution promote democratization, they do so by acce
lerating the same causal mechanisms. The next round of research and theory
on democratization requires identification, verification, and connection of
the relevant causal mechanisms.
