Illustrating
Contested Regions according to the map annexed to the
Treaty of Alliance
"The
Serbian-Bulgarian treaty of 13 March 1912 made provision for the
partition of Macedonia along the following lines: 'all the
territory north of the Sar range' was
to go to Serbia; 'all the region east of the Rhodope range and
the Struma valley' was to go to Bulgaria. Bulgaria hoped the
intervening country should form an
'autonomous Macedonia', but, if this should prove impossible, a
new line was to be drawn leaving Kumanovo, Skoplje and Debar to
Serbia, and giving Kratovo, Veles,
Bitolj (Monastir) and Ohrid to Bulgaria. Serbia undertook to
make no claim south of the line; Bulgaria reserved the right to
claim territory to the north, in which case
Russia was to act as arbitrator. The area of overlapping claims
was known as the 'Contested Zone'. "
