Vis
The general term used in Roman law for criminal violence. The
lex Plotia
(B.C. 89) was the first regular statute punishing those who pillaged houses, occupied public
places in arms, and assembled armed men for the purpose of overawing the Senate or the
magistrates. Several
leges Iuliae of Iulius Caesar and of Augustus were also
passed to complete and consolidate previous enactments. Two kinds of vis are
mentioned—
vis publica, which probably meant violence
immediately directed against the State, and
vis privata, which would be
violence primarily against an individual right, but criminal because it interfered with public
order. The punishments assigned by the
leges Iuliae ranged from death
(house-pillaging, abduction, riot resulting in death) to exile. See Rein,
Criminalrecht
der Römer, pp. 732 foll.
