Ninjas were real historical assassins.

the verdict
INSUFFICIENT LEANING
Recorded sources
3 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that Ninjas were real historical assassins?

Unclear. Two sources treat ninja as a real historical group of spies and assassins in feudal Japan, though one is a role-playing game supplement and the other notes that a particular famous ninja is likely legendary rather than historical. Neither source fully settles the claim that ninjas were real historical assassins.
