Ukraine and Bulgaria first established diplomatic relations on February 9, 1918, with the signing of the
Treaty of Brest-Litovsk during the
First World War. The treaty was signed between the
Soviet Union (which had recently come to power after overthrowing the tsarist government of the
Russian Empire) and the
Central Powers (The
German Empire, the
Austro-Hungarian Empire, the
Ottoman Empire, and the
Kingdom of Bulgaria). The Soviet Union agreed to withdraw Russian troops from the
Eastern Front of the war and make peace with the Central Powers. Part of the agreement was the establishment of diplomatic relations between the governments of the Central Powers and the governments of the newly independent Eastern European republics that had gained independence from Russia during the
Russian Revolution. One of these newly independent Eastern Europeans states was the
Ukrainian People's Republic. Thus, the treaty caused Bulgaria and Ukraine to establish diplomatic ties.
Oleksandr Shulhin, a prominent Ukrainian politician, became the first Ukrainian ambassador to Bulgaria. The diplomatic relations were ultimately short lived, as the Ukrainian People's Republic was eventually forced to join the Soviet Union in 1922. Coming under supremacy from Moscow once again, Ukraine was forced to break off the diplomatic relations it had established during its brief experience with independence. Bulgaria and Ukraine re-established diplomatic relations on December 13, 1991, shortly after Ukraine gained independence from the Soviet Union and became the modern sovereign state known as the Republic of Ukraine. The two countries have enjoyed positive and productive relations ever since 1991. Bulgaria, as a member of the
European Union, has supported Ukraine in its efforts to become closer with the EU and with Western Europe in general. Bulgaria supported Ukraine's sovereignty over the
Crimean Peninsula during the
annexation of Crimea by the Russian Federation in 2014. During the crisis, then President of Bulgaria,
Rosen Plevneliev, stated "Bulgaria is for preserving the sovereignty, the territorial integrity and the democratic future of Ukraine." In addition to the Ukrainian embassy in Sofia, a Bulgarian embassy was established in the Capital of Ukraine,
Kyiv (see
Embassy of Bulgaria, Kyiv). The two countries also have
consulate-generals in each others' borders. Bulgaria maintains a consulate-general in
Odesa and Ukraine maintains a consulate-general in
Varna. The Ukrainian embassy in Sofia provides various consular services, such as "visa, passport, document legalization [and] emergency travel assistance". The embassy's stated purpose is to "help the government of Ukraine to maintain cordial economic, political, cultural, social and other transnational ties with the government of Bulgaria." == Known ambassadors from Ukraine to Bulgaria ==
