When were the Ten Commandments removed from schools?

The Ten Commandments were never officially mandated to be *in* public schools in the United States, so there was no official removal. However, their display in schools has been a source of significant legal battles and controversy. Court cases, beginning in the mid-20th century, consistently ruled against the unconstitutionality of government-sponsored displays of the Ten Commandments in public schools, citing the Establishment Clause of the First Amendment. These rulings didn't lead to a specific date of removal, but rather a gradual process of challenges and legal decisions leading to their removal from many schools over several decades.
