When and why did the tie become a popular and almost necessary piece of clothing for men in the 1900's (and before)?

I recently saw a photo of a group of boys in 1916 and they were all wearing ties, I then had a search and in almost every photo, no matter there age if there was a male in the photo they would be wearing a tie. Why was this such a crucial piece of clothing? And how did it come about to be so popular?

There is certainly room for someone to write specifically about the decline of the necktie, but you may be interested in an answer I wrote about the casualization of dress in the twentieth century, which this is a factor of.
