Something that is alleged or claimed to be true (a legal or archaic term).
From Latin 'allegatum,' the neuter past participle of 'allegare' meaning 'to cite' or 'to allege.' This is a learned Latin-derived term used in formal and legal contexts.
This is one of those beautiful Latin words that English scholars kept using in legal documents, even though English already had 'allegation'—it gave lawyers and scholars a fancy, precise way to refer to a claimed fact in court.
