When was school uniform made?

The concept of school uniforms can be traced back to the 16th century in England, where certain schools, like Christ's Hospital, introduced uniforms to create a sense of equality among students. However, the widespread adoption of school uniforms in modern education began in the 19th century, particularly in the United States and the UK. By the mid-20th century, many schools had formalized uniform policies as a means to promote discipline and school identity.
