Hungary in World War I instance of country in World War I
At the outbreak of World War I in August 1914, Hungary was part of the Dual Monarchy of Austria-Hungary. Although there are no significant battles specifically connected to Hungarian regiments, the troops suffered high losses throughout the war as the Empire suffered defeat after defeat. The result was the breakup of the Empire and eventually, Hungary suffered severe territorial losses by the closing Trianon Peace Treaty.The Empire during the outbreak of the war
In 1914, Austria-Hungary was one of the great powers of Europe, with an area of 676,443 km2 and a population of 52 million, of which Hungary had 325,400 km2 with population of 21 million. By 1913, the combined length of the railway tracks of the Austrian Empire and Kingdom of Hungary reached 43,280 kilometres (26,890 miles). In Western Europe only Germany had more extended railway network (63,378 km, 39,381 mi); the Austro-Hungarian Empire was followed by France (40,770 km, 25,330 mi), the United Kingdom (32,623 km, 20,271 mi), Italy (18,873 km, 11,727 mi) and Spain (15,088 km, 9,375 mi). By 1910, the total length of the rail networks of Hungarian Kingdom reached 22,869 kilometres (14,210 miles), the Hungarian network linked more than 1,490 settlements. Nearly  half (52%) of the empire's railways were built in Hungary, thus the railroad density there became higher than that of Cisleithania. This has ranked Hungarian railways the 6th most dense in the world (ahead of Germany and France).
The Austro-Hungarian Empire conscripted 7.8 million soldiers during the WW1.Although the Kingdom of Hungary composed only 42% of the population of Austria-Hungary, the thin majority – more than 3.8 million soldiers – of the Austro-Hungarian armed forces were conscripted from the Kingdom of Hungary during the First World War.
Austria-Hungary was more urbanized (25%) than its actual opponents in the First World War, like the Russian Empire (13.4%), Serbia (13.2%) or Romania (18.8%). Furthermore, the Austro-Hungarian Empire also had a more industrialized economy and higher GDP per capita than the Kingdom of Italy, which was economically the most developed opponent of the Empire by far.
On 28 June 1914 Gavrilo Princip assassinated Archduke Franz Ferdinand of Austria. Before entering the war, only the prime minister Count István Tisza hesitated, unconvinced that it was the best time to engage in battle. As soon as Germany promised to neutralize the Kingdom of Romania and promised that no territories of the Kingdom of Serbia would be annexed to Austria-Hungary, he then decided to support the war.
After the ultimatum sent to Serbia by Franz Josef I, the war broke out and soon spread over much of Europe and beyond.
