Question

Which country made the first declaration of war?
A) Serbia
B) Austria-Hungary
C) Italy
D) Germany

Answer 1

Hint: The Constitution awards Congress the solitary ability to announce war. Congress has pronounced conflict on 11 events, including its first announcement of battle with Great Britain in 1812. Congress supported its last conventional affirmation of battle during war II.

Complete answer:
Gavrilo Princip was a Serbian terrorist who assassinated Archduke Franz Ferdinand in Sarajevo. The assassination of Archduke Franz Ferdinand enraged Austria-Hungary, consistent with this evidence. This set out a sequence of events that eventually led to the outbreak of the war.

Because of the assassination of Austrian Prince Francis Ferdinand and his wife Sophia on June 28, 1914, Austria-Hungary declared war on Serbia for the primary time. Archduke Ferdinand and his wife Sophia were slain in Sarajevo, Serbia's capital, by a student of the political unit "Black Hand." On July 23, Austria issued an ultimatum to Serbia, containing eleven requests. aside from people who would have resulted in the loss of Serbia's sovereignty, most of them were accepted. On July 28, 1914, Austria declared war on Serbia.

Benito Mussolini, the ruler of Italy, declares war on France and therefore the UK on June 10, 1940, after refusing to pledge formal allegiance to either side within the struggle between Germany and therefore the Allies. On September 3, 1939, two days after Germany invaded Poland, the UK declared war on Germany. Later that day, France declared war on Germany.

So, due to the assassination of Austrian Prince archduke and his wife Sophia on June 28, 1914, Austria-Hungary declared war on Serbia for the primary time.

Thus, the correct answer is option ‘B’ i.e, Austria-Hungary.

Note: The primary warfare, sometimes called WWI or WW1, was a worldwide conflict that began in Europe and lasted from 28 July 1914 to Martinmas 1918. The Good War also referred to as "the war to finish all wars," saw quite 70 million military people, including 60 million Europeans, mobilised, making it one of the biggest wars in history.
