Everything started from assassination of Archduke Franze Ferdinand.He was killed by Serbian terroists.Austria declared war on Serbia,while Russia and France were alliances.Austria,Germany and Italy were alliances too!So Germany promised to protect Austria like Russia to Serbia.France promised to protect Russia.Germany declared war on Russia.After 2 days they declare war on France.German ruler was Kaiser Wilhaim 2nd.His plan was to take under control France and then fight Russia.BUT,first of all,he had to cross Belgium.Major powers (including Germany) promised Belgium not to invade them.So they asked to cross them,but they dismissed.So...they invaded on Belgium,while Britain didn't seem to enjoy it.So they said that Belgium needs to be protected.But,for real,they wanted to stop Germany becoming powerful.Germany still in Belgium=Britain joins the war.

That's how WWI started.So,basically event that sparked WWI was assassination of Archduke Franze Ferdinand.
