In the early 20th century,
Serbia was economically a satellite of the
Habsburgs, its major export being pork, most of which was bought by
Austria-Hungary. When Serbia started trying to evade economic and political control by the Habsburgs and to build links with other countries, particularly
Bulgaria,
Germany and
France, the Hungarian government decided to punish the Serbs with economic sanctions. Specifically, in an attempt to reduce its economic dependence on Austria-Hungary, Serbia began to import French, rather than Austro-Hungarian, munitions and established a
commercial treaty with Germany in 1904 and a
customs union with Bulgaria in 1905 that ended the sale of tariff-laden Austrian goods in Serbia. == History ==
