World-War III

Known to the as World-War III and to the  as The Great Muggle/Wizard War, the war was between all great muggle nations and the wizards within. It begun in 2010 and was started by Falin Snape and a gang of his friends, who exposed the  to muggles, resulting in wide-spread panic and a hasty declaration of war. Falin and the rest of Dead Pegasus fought on the muggles' side for most of the war, which lasted less than a year, until several muggle soldiers mistook Dead Pegasus for wizards in 2011 and killed them all. Falin woke from his death two days later, and in a grief-stricken outrage, slaughtered hundreds of muggle soldiers, which ended the war in favor of wizards everywhere.

Muggle Casualties: 7 million Wizard Casualties: 240 thousand

Though the wizards lost fewer people, they sustained a heavier blow, considering that their population in relation to muggles was ten times less.
