Traditionally, the murder of Austria-Hungary's crown prince Franz Ferdinand was the thing that started it all. Another important factor was the resulting invasion of Serbia by Austrian troops, which started a whole chain of other countries getting involved because of offensive/defensive mutual support-treaties that bound them. Russia got involved because it felt bound to support Serbia, Gemany was bound to support Austria-Hungary and Russia and France also had a mutual support treaty. Germany invaded France as a preventive strike since (watch closely!) France would have otherwise been bound to attack Germany when Germany attacked Russia in support of Austria which had attacked Serbia which had called in the support of Russia.
It is one of history's little ironies that the Serbian troops needed no-one's help as it turned out. They quickly kicked back the Austrian troops across the border and if everyone had just minded their own business, the Austrians and Serbians probably would have come to a quick face-saving agreement.

One significant factor that contributed to World War I was the complex system of alliances that developed in Europe during the early 20th century. Major powers, including Germany, Austria-Hungary, France, Russia, and Britain, formed alliances that promised mutual defense. This web of agreements meant that a conflict involving one nation could quickly escalate into a broader war, as allied nations were drawn in to support their partners. The assassination of Archduke Franz Ferdinand of Austria-Hungary in 1914 triggered these alliances, leading to a rapid escalation into a full-scale war.

One significant factor that contributed to the entry of the U.S. into World War I was the unrestricted submarine warfare conducted by Germany, which threatened American commercial shipping and lives. The sinking of the Lusitania in 1915, where American passengers were killed, heightened public outrage. Additionally, the interception of the Zimmermann Telegram, in which Germany proposed a military alliance with Mexico against the U.S., further galvanized American support for entering the war. These provocations shifted public opinion and government policy towards involvement in the conflict.
