The Kaiser of Germany during WWI. Your history book spells it as William II. They are wrong. Please inform your class of this stupidity.
Student 1: So William II urged Germany to honor the Dual Alliance?
Student 2: No! Don't you read any other primary source documents? It's pronounced WILHELM! Wilhelm II.
Student 1: Was he a Nazi?
Student 2: That's WW2, you uneducated twat! Even though the Nationalist Socialist German Worker's Party came to power in 1933, you are STILL WRONG.
Student 1: You are such a nerd.
