Will Durant, in The
Reformation (1957), cites Juan Antonio
Llorente, General Secretary of the
Inquisition from 1789 to 1801, as estimating
that 31,912 people were executed from
1480-1808. He also cites Hernando de Pulgar,
a secretary to Queen Isabella, as estimating
2,000 people were burned before 1490.
Philip Schaff in his History of the
Christian Church gave a number of 8,800
people burned in the 18 years of Torquemada.
Matthew White, in reviewing these and other
figures, gives a median number of deaths at
32,000, with around 9,000 under Torquemada
[1].
R. J. Rummel describes similar figures as
realistic, though he cites some historians
who give figures of up to 135,000 people
killed under Torquemada. This number
includes 125,000 asserted to have died in
prison due to poor conditions, leaving
10,000 sentenced to death. (Death rates in
medieval and early modern prisons were
generally very high, thanks in part to
inadequate sanitary conditions and a poor
diet.) There are no death toll figures
available for the massacres of 1391, 1468 or
1473. These numbers will likely never be
known.
