Russia rapidly mobilised its forces, contributing to the start of World War I
On June 28, 1914, the assassination of Archduke Franz Ferdinand, the heir to the Austro-Hungarian throne, and his wife, Sophie, Duchess of Hohenberg, by a Serbian nationalist in Sarajevo sparked a chain of events that led to World War I. Austria-Hungary, unable to conclusively prove Serbia's involvement, nonetheless accused Serbia of plotting the assassination and threatened invasion. In response, Russia, which had no formal treaty with Serbia but had interests in the Balkans, rapidly mobilized its forces along the border with Austria-Hungary to deter an invasion of Serbia. This mobilization contributed significantly to the escalation of tensions and the outbreak of World War I.
Russia's decision to mobilize its military forces was a critical moment in the July Crisis, a period marked by intense diplomatic and military maneuvering. Russia's mobilization signaled its commitment to supporting Serbia, its Slavic ally, and was a direct response to Austria-Hungary's aggressive posturing towards Serbia. Russia's mobilization, however, carried the risk of provoking a wider conflict, as Germany, an ally of Austria-Hungary, viewed Russian mobilization as a potential threat.
The German government, aware of Russia's military strength and concerned about maintaining its own influence, responded to Russia's mobilization with alarm. On July 31, 1914, Germany demanded that Russia demobilize its forces, but Russia refused. As a result, on August 1, Germany declared war on Russia, marking the official entry of both nations into World War I.
Russia's rapid mobilization of its forces was driven by its strategic interests in the Balkans and its desire to support Serbia. Russia sought to gain a military advantage over Germany and Austria-Hungary by controlling the Balkans region. Additionally, Russia's mobilization was influenced by its alliance with France, which provided military support and shared Russia's interest in countering German and Austro-Hungarian influence.
The mobilization of Russian forces had significant consequences, leading to huge losses on the Eastern Front. The Central Powers, which included Germany and Austria-Hungary, faced a much larger but disorganized Russian force. The conflict in the East became a war of movement, with staggering losses on both sides. Russia's mobilization, therefore, played a crucial role in the escalation of tensions and the eventual outbreak of World War I, marking the beginning of a global conflict that would reshape the world order.

Germany invaded Belgium, prompting Britain to declare war on Germany
The German invasion of Belgium, which began on 4 August 1914, was a military campaign intended to bring German armies into positions from which they could invade France. On 2 August, Germany sent an ultimatum to Belgium, demanding passage through the country. Belgium refused, and Britain guaranteed military support. On 4 August, German troops crossed the border and began the Battle of Liège. This invasion violated a treaty signed by major European powers, including Britain, in 1839, which guaranteed Belgium's neutrality and independence.
Britain's entry into the war was a reaction to anxieties about the balance of power in Europe and its own security. By violating Belgian neutrality, Germany positioned itself as the belligerent aggressor, making British intervention a moral issue about the rights of small nations. The invasion of Belgium also served as a catalyst for Italy to join the Allies.
The German invasion of Belgium in 1914 was not the only time Belgium was invaded by Germany. In May 1940, during World War II, Germany invaded Belgium, Luxembourg, and the Netherlands as part of the Battle of France. The Belgian army surrendered after 18 days, and the Belgian government fled the country, first to France and then to London. The German occupation of Belgium lasted four years, until September 1944, when Allied forces reached Belgium.
In the lead-up to the 1940 invasion, the Belgian government secretly shared defence policies, troop movement information, and other sensitive information with the French military attaché in Brussels. However, French forces were not allowed to enter Belgium, even as German invasion plans became imminent. The Belgian government retained a suspicious posture towards France, considering them as much a danger to Belgian sovereignty as the Third Reich.

Germany declared war on Russia on 1 August 1914
On 28 June 1914, Archduke Franz Ferdinand, the heir to the Austro-Hungarian throne, and his wife were assassinated by a Serbian-backed terrorist. This event sparked the First World War. Austria-Hungary, with German encouragement, declared war on Serbia on 28 July, leading Russia to issue an ultimatum to Vienna, warning Austria-Hungary against attacking Serbia. Despite this, Austria-Hungary invaded Serbia, and Russia commenced mobilizing its reserve army along the border of Austria-Hungary.
In response to the Russian mobilization, Germany demanded that Russia demobilize within twelve hours. When Russia did not comply, Germany declared war on Russia on 1 August 1914. Germany's war plan prioritized an offensive against France, which it declared war on two days later. Germany deployed its armies through Belgium, with the aim of encircling Paris. This violation of Belgian neutrality, along with British fears of German domination in Europe, brought Britain and its empire into the war against Germany on 4 August.
At the start of the conflict, Russian forces launched offensives against both Germany and Austria-Hungary. Russia's support of Serbia had also brought France into the conflict. Germany's declaration of war on Russia, therefore, set the scene for a global war, with European powers and their empires taking sides and preparing for battle.

Russia's ally, France, ordered its own mobilisation on 1 August 1914
On 28 July 1914, Austria-Hungary declared war on Serbia, effectively beginning the First World War. This declaration came one month after Archduke Franz Ferdinand of Austria and his wife were assassinated by a Serbian nationalist in Sarajevo. As one of the first nations to declare war, Austria accused Serbia of plotting the assassination and threatened invasion.
Russia rapidly mobilised its forces in response, resulting in huge losses and contributing to revolutions at home. Russia's ally, France, ordered its own mobilisation on 1 August 1914. France knew that it faced German invasion but was clear that it must stand with Russia. Many Frenchmen also hoped that war could settle old grievances with Germany, which stemmed from the 1870s.
The mobilisation in France was established by the State-Major General of the Army, with planning led by the general of division, Joffre. The plan, known as Plan XVII, was established in 1913 and validated by the Council of Superior War. It involved the mobilisation of men, their concentration at the borders, their organisation into several armies, and the directions of the first offensives.
On 1 August 1914, war erupted into the lives of millions of families across France. Most people thought the conflict would last just a few weeks. However, before the month was out, 27,000 French soldiers died on 22 August alone, marking the worst catastrophe in French military history. Refugees streamed into France as the German army advanced, and citizens of enemy countries living in France were viciously scapegoated.
On 2 August, the British Cabinet agreed to support Belgium if there was a substantial violation of its neutrality. Germany invaded Belgium on 4 August, which tipped the balance for Britain, leading to their entry into the war.

The German military supported the idea of an Austro-Hungarian attack on Serbia
On 2 July 1914, the Saxon Ambassador in Berlin reported to his king that the German Army wanted Austria-Hungary to attack Serbia as soon as possible. He believed that Germany was more prepared for war than either Russia or France, and that the time was right for a general war. The following day, the Saxon military attaché in Berlin reported that the German General Staff "would be pleased if war were to come about now".
On 4 July, Wilhelm II declared that he was entirely for "settling accounts with Serbia". He ordered the German ambassador in Vienna, Count Heinrich von Tschirschky, to stop advising restraint, writing that “Tschirschky will be so good to drop this nonsense. We must finish with the Serbs, quickly. Now or never!”. Tschirschky then told the Austro-Hungarian government that "Germany would support the Monarchy through thick and thin, whatever action it decided to take against Serbia".
On 12 July, it was reported that everyone in the German government wanted to see Austria-Hungary declare war on Serbia immediately, and they were tired of Austro-Hungarian indecision about whether to choose war or peace. By 14 July, Tisza agreed to support the war, fearing that a policy of peace would lead to Germany renouncing the Dual Alliance of 1879. That same day, Germany decided to do everything within its power to cause an Austro-Serbian war.
On 28 July, one month after Archduke Franz Ferdinand of Austria and his wife were assassinated by a Serbian nationalist, Austria-Hungary declared war on Serbia, effectively beginning the First World War. Austria-Hungary had determined that the proper response to the assassinations was to prepare for a possible military invasion of Serbia. After securing the unconditional support of its powerful ally, Germany, Austria-Hungary presented Serbia with a rigid ultimatum on 23 July 1914. Although Serbia accepted almost all of Austria's demands, the Austrian government broke diplomatic relations on 25 July and continued with military preparedness measures.
