In the 1340s, Franciscan missions were launched against alleged "heresy" in Bosnia; prior to this, there had been no Catholics – or at least no Catholic clergy or organization – in Bosnia proper for nearly a century.
Under 1340-talet, lanserades franciskanorden mot det påstådda "kätteriet" i Bosnien, men innan detta hade det inte funnits några katoliker i Bosnien - eller åtminstone någon katolsk teologisk organisation eller katolska präster.
