Complete answer:
The First World War was precipitated by the assassination of their heir to the throne of Austria-Hungary, Archduke Francis Ferdinand.
In this context, describe the following:
The world war began just after the Sarajevo crisis took place on June 28, 1914 Archduke Ferdinand along with his wife Sophia were assassinated by a student of the ‘Black hand’, at Sarajevo, the capital of Serbia. War on Serbia was declared by Austria on 28th July 1914.
Some of the consequences of the First World War were:-
The war divided the major powers into two groups as Allied and Axis. These five major powers were (allied and axis) in the hostilities. For example:- Germany, Austria-Hungary, France, England, and Russia. The Hapsburg dynasty in Austria-Hungary was completely destroyed, in the First World War. After World War, Austria and Hungary became separate independent states. Austria was pressured to sign the treaty of Saint-Germain-en-Laye on 10th September 1919. Under this Treaty, the Austro-Hungarian Empire had to be dissolved. Germany had surrendered on November 11, 1918, in front of the opposite group. All nations had agreed to stop fighting, while the terms of peace were negotiated. Germany and the Allied Nations (including Britain, France, Italy, and Russia) signed the Treaty of Versailles, formally end the war on June 28, 1919. The First World War only brought slaughter, carnage, and mass destruction.

Note: After the War, Austria got separated and recognized the independence of Hungary, Czechoslovakia, Poland, and the Kingdom of Serbs, Croats and Slovenes. The treaty demanded 'war reparations' of large sums of money by the Allies group. Hungary was pushed to sign the Treaty of Trianon. Hungary lost a lot of its lands to the neighboring countries for example:- Romania, Yugoslavia, and Czechoslovakia. Hungary was partitioned in this war and lost its two-thirds territory with the loss of one-third of its Hungarian population.
