Several students and parents in Des Moines organized a protest of the Vietnam war. Students were to wear black arm bands to school in protest. When the school found out they warned all the students and parents that anyone wearing the armbands would be would be suspended. The Tinker children wore their armbands to school (they were the only ones of the group to do so) and were suspended. Mr and Mrs. Tinker filed suit claiming that the school violated the children's right to freedom of speech and expression. The school claimed that the armbands were disruptive.
