Haitian heads of state

Found this interesting poster in the office of the neighbourhood committee that I work with.

It shows all Haitian heads of state.
57 different heads of state since 1804.
Of which 30 years the Duvaliers (papadoc and babydoc) were in power. After the fall of the Duvaliers in 1986, 11 presidents followed in a 10 year timespan.
