When and where has sortitional selection been used?
Sortitional selection was a central and defining feature of the first Athenian democracy. It was used to select both legislative and administrative functions. There were also a small number of meritocratic elective offices, particularly for the military and the treasury.
Sortitional selection was also used in Florence and Venice in the late medieval period. The system was instituted in order to break the power of political factions. Sortition was also used during the French Revolution.
Sortition is also used by the Amish to choose their bishops.
