  The Jovian Trojans are two swarms of small objects that share Jupiter's
orbit, clustered around the leading and trailing Lagrange points, L$_4$ and
L$_5$. In this work, we investigate the Jovian Trojan population using the
technique of astrocladistics, an adaptation of the `tree of life' approach used
in biology. We combine colour data from WISE, SDSS, Gaia DR2 and MOVIS surveys
with knowledge of the physical and orbital characteristics of the Trojans, to
generate a classification tree composed of clans with distinctive
characteristics. We identify 48 clans, indicating groups of objects that
possibly share a common origin. Amongst these are several that contain members
of the known collisional families, though our work identifies subtleties in
that classification that bear future investigation. Our clans are often broken
into subclans, and most can be grouped into 10 superclans, reflecting the
hierarchical nature of the population. Outcomes from this project include the
identification of several high priority objects for additional observations and
as well as providing context for the objects to be visited by the forthcoming
\textit{Lucy} mission. Our results demonstrate the ability of astrocladistics
to classify multiple large and heterogeneous composite survey datasets into
groupings useful for studies of the origins and evolution of our Solar system.
