"How should we make theoretical sense of Haiti's instability in the past two decades? The central hypothesis of this study is that the 29-year Duvalier dicatatorship was stabilized through the paramilitary. In the past two decades, unofficial and illegitimate paramilitaries have continued to be a constant factor in Haitian politics, each of them attempting to secure partisan political power, but none with a monopoly on coercion. Consequently, the type of institution that was most able to stabilize Haiti from 1957-1986, albeit at a horrendous cost, has been the most prominent de-stabilizing force since that time."
