Relatively numerous sites in which ceramics of
Brnjica type were found in the Vardar basin as well as
in the north of Greece up to Thessaly, point to popu-
lation movements from the central Balkans towards
the Mycenaean territory at the time when the Brnjica
community flourished, reached its peak and, like others,
developed ferrous metallurgy, but neglected the pro-
tection of the northern regions of its territory. Under
such conditions, the cultural group from the Iron Age I b
phase in the Morava basin found ways to leave the
Velika Morava valley and reach the Juzna Morava basin
up to the Grdelica Gorge, undoubtedly causing move-
ments further to the south in response. The powerful
advance of cultural groups from the north (from the
Serbian Danube valley and the Velika Morava basin) is
proved not only by the cannelured ceramics of the Iron
Age I type, but also by bronze artefacts (decoration need-
les, axes-kelts, razors, bracelets) from the Hisar site in
Leskovac.
From that moment on, the archaeological
material of the Juzna Morava basin north of Grdelica
Gorge is characterized by a mixture of the material
culture of the Iron Age I community in the Morava
basin with traditional forms of the Brnjica population
in proportionally 10: 1 during the Brnjica I b phase, up
to 5:1 during the Brnjica II a phase, and 1: 4 in the last
phase of this cultural group.48
