BULGARIA ENTERS WORLD WAR I<\/h2>\n\n\n\n

World War I<\/a> erupted during the summer of 1914 in an event that historians refer to as the\u00a0July Crisis<\/a>.\u00a0 In short, this crisis was caused by the\u00a0assassination of Austrian Archduke Franz Ferdinand<\/a>, which led to the major European powers engaging in a conflict.\u00a0 Ferdinand<\/a> was assassinated on June 24th, 1914 due to a rise in nationalism in the southeastern region of Europe referred to as the Balkans.\u00a0 The Balkans actually experienced a great deal of conflict in the years before the outbreak of World War I.\u00a0 For example, two Balkan Wars (First Balkan War<\/a> and Second Balkan War<\/a>) took place in 1912 and 1913.\u00a0 Bulgaria was a significant nation in these conflicts, which ultimately helped set the stage for the outbreak of World War I.\u200b<\/p>\n\n\n\n

Franz Ferdinand\u00a0was the Archduke of Austria-Hungary and next in line to rule over the empire. Ferdinand and his wife Sophie were assassinated on June 28th, 1914 in Sarajevo, the capital of the Austro-Hungarian province of Bosnia and Herzegovina, while there on a visit to inspect the military forces.\u00a0 The assassin was\u00a0Gavrilo Princip<\/a>.\u00a0 Just nineteen years old at the time, Princip was a member of the\u00a0Black Hand<\/a>, which was a Serbian nationalist organization that existed in the early part of the 20th century.\u00a0 Historians consider this event to be one of the main causes of World War I<\/a>, as it caused many of the European nations to increase their hostility against one another.\u200b<\/p>\n\n\n\n

For its part, Bulgaria immediately declared itself neutral in the conflict.  This was due to several factors, but for the most part Bulgaria was not interested in getting involved in a major conflict with the other European powers.  Bulgaria was still recovering economically and militarily from the two Balkan Wars, and did not want to commit itself to another conflict.  As well, in the early days of World War I, it was assumed that the war would be over relatively quickly.  As such, officials in Bulgaria did not see the benefit of participating in a conflict that would be over in just a few months.  Regardless, both the Central Powers and the Allied Powers presented Bulgaria with options to join the war effort on their side.  These included proposals directly given to Ferdinand I, the Tsar of Bulgaria.  However, Bulgaria remained neutral throughout 1914, under the leadership of Bulgarian Prime Minister Vasil Radoslavov.\u200b<\/p>\n\n\n\n

As the war raged on throughout the rest of Europe, the main European nations continued to put pressure on Bulgaria and the Bulgarian government to join the war effort.\u00a0 In fact, since World War I was characterized by a stalemate with little overall military movement, many of the European nations believed that Bulgaria could be an important factor in tipping the balance of power in their favor.\u00a0 Bulgaria finally entered World War I on September 6th, 1915 when it formalized an agreement with the Central Powers<\/a>.\u00a0 The agreement angered the government of Serbia, which viewed it as a threat in the Balkans.\u00a0 As a result, Bulgarian declared war on Serbia on October 14th, in 1914, when it invaded Serbia.\u200b<\/p>\n\n\n\n

BULGARIA IN WORLD WAR I – ARMY<\/h2>\n\n\n\n

When it entered the war, Bulgaria had approximately 280,000 soldiers and by the end of the war over 1.2 million Bulgarians had served in the Bulgarian Army.  In 1914, Bulgaria was still recovering from the events of the two Balkan Wars, which occurred from 1912 to 1913.  As such, Bulgaria demobilized its army and was not militarily ready for the outbreak of World War I in 1914.  Regardless, Bulgaria\u2019s armed forces were divided into three armies, which were created through conscription.<\/p>\n\n\n\n

Bulgarian men were eligible for conscription at the age of 20, and served at least 5 years in the Bulgarian Army.  Afterwards, the men served in either the infantry or Army Reserve until they were approximately 40 years old.  Bulgarian men older than 40 years old served in the National Militia.  As such, Bulgaria had a system of conscription that allowed it to boast a relatively large army.  Therefore, when Bulgaria made the decision to join the fighting of World War I, it was easily able to mobilize its forces.\u200b<\/p>\n\n\n\n

However, Bulgaria was a smaller nation and therefore lacked the ability to match the other European powers in other aspects of the military.  For instance, while Bulgaria had over 1,200 artillery guns at the start of World War I, it struggled to produce the necessary ammunition for them.  As well, Bulgaria had a small navy and air force in comparison to other nations of the time.\u200b<\/p>\n\n\n\n

During World War I, the Bulgarian Army was led by commander-in-chief Nikola Zhekov.  In fact, he led the Bulgarian Army throughout the entirety of Bulgaria\u2019s time in the First World War.\u200b<\/p>\n\n\n\n

BULGARIA IN WORLD WAR I – MAJOR BATTLES<\/h2>\n\n\n\n

Although Bulgaria was not one of the major European nations of the time, it did exert a great deal of influence in the Balkans.\u00a0 As such, Bulgarian forces were primarily active in the Balkans, including the Serbian Campaign.\u00a0 In general, the landscape of Europe in World War I was divided into a few different \u2018fronts\u2019.\u00a0 For instance, the Western Front<\/a> was located on the western-half of Europe and included a line of trenches that stretched throughout much of northern France and Belgium.\u00a0 Whereas the Serbian Campaign was fought throughout the region of the Balkans, including Serbia, Montenegro and Albania.\u00a0 As part of its agreement with the Central Powers, Bulgaria was responsible for helping the war effort in the Balkans.\u00a0 As well, Bulgaria wanted to gain control over sections of the region due to a rising sense of nationalism.\u200b<\/p>\n\n\n\n

From the start of World War I, conflict between Bulgaria and Serbia was a certainty.  This was due to several factors, but mostly a result of Bulgaria seeking new territories in the Balkans following the earlier Balkan Wars.  As such, the Serbian Campaign of World War I was the first main military activity for Bulgarian forces in the war.  In fact, Bulgaria invaded Serbia on October 14th, 1915 after Germany and Austria-Hungary had already begun their own attacks.\u200b<\/p>\n\n\n\n

Regardless, the Bulgarian Army experienced a great deal of success at the start of the Serbian Campaign and were easily able to overrun the Serbian forces positioned along the border.  In fact, the Bulgarian First and Second Armies were able to push into Serbia throughout October, which allowed them to capture several significant towns.  Furthermore, the Serbian forces were in full retreat and lost control of several key railroads and other transportation routes.\u200b<\/p>\n\n\n\n

The Serbian Campaign continued throughout 1915, with Austro-Hungarian, German and Bulgarian forces combining their efforts.  This proved valuable as the central Powers were able to defeat Serbia and occupied the country for the remainder of World War I.  The Serbian Campaign ended on November 24th, 1915 and Serbia wasn\u2019t liberated until November 1st, 1918.\u200b<\/p>\n\n\n\n

BULGARIA IN WORLD WAR I – HOME FRONT<\/h2>\n\n\n\n

An important aspect of the First World War for all of the countries involved was the impact it had on the home front<\/a>.\u00a0 This was also true in Bulgaria, which experienced impacts on daily life for its citizens.\u00a0 At the outbreak of World War I, in 1914, Bulgaria had a population of about 4.8 million people, which lived primarily in a rural setting.\u00a0 As such, the country lacked the industrial capabilities of the other European nations, since it did not have the industrial workers or factories required.\u00a0 This caused Bulgaria to struggle economically during the timeframe of World War I, which created hardships for the people on the home front.\u200b<\/p>\n\n\n\n

Another important factor of the Bulgarian home front in World War I was the role and structure of the government.  At the time, Bulgaria was a constitutional monarchy that was ruled over by a Tsar, which is a title for monarchs in Eastern Europe.  In fact, Bulgaria gained its independence as a state in 1908, and Ferdinand I was crowned the Tsar.  Ferdinand I continued to reign as the Tsar of Bulgaria throughout World War I, until he abdicated the throne in 1918, when Bulgaria accepted defeat for its roles in the war.  The nature of Ferdinand\u2019s rule over Bulgaria allowed the government to effectively control the civilian people and mobilize them for war.\u200b<\/p>\n\n\n\n

One of the ways that the Bulgarian government controlled its citizens during World War I was through the use of propaganda<\/a>.\u00a0 In fact, the use of propaganda was common throughout all of the countries of World War I, and played a significant role in the history of the war.\u00a0 In order to promote support for the war and other initiatives, the government of the time used propaganda to convince citizens of certain messages.\u00a0 For example, the Bulgarian government issued propaganda that worked to recruit soldiers for the war, ration certain items and to demonize the enemy.\u00a0 Bulgarian citizens on the home front were subjected to constant messaging to ensure they supported the war effort and to maintain the push towards victory.\u200b<\/p>\n\n\n\n

BULGARIA IN WORLD WAR I – SIGNIFICANCE<\/h2>\n\n\n\n

World War I was a highly important event in the history of Bulgaria.  First, and foremost, over 1.2 million Bulgarian soldiers served during World War I.  As well, approximately 75,000 Bulgarian soldiers died as a result of military action during the war.\u200b<\/p>\n\n\n\n

Second, the terrible losses suffered by Bulgaria were characteristic of the overall nature of the fighting in World War I.  This was due to the terrible waste of humanity that resulted from trench warfare and the military strategy of World War I.  As well, Bulgarian armies fought primarily in the Serbian Campaign.\u200b<\/p>\n\n\n\n

Beyond this, World War I was significant for the country of Bulgaria due to the outcome of the war and the result for the country.  As stated above, Bulgaria accepted its defeat in World War I, which led to the abdication of Tsar Ferdinand I.  Following his abdication, Ferdinand\u2019s son, Boris III, became to new Tsar of the country.  Finally, Bulgaria\u2019s participation in World War I was finalized in the Treaty of Neuilly of 1919.\u200b<\/p>\n","protected":false},"excerpt":{"rendered":"
