First of all, Ivy League refers to Brown University, Columbia University, Cornell University, Dartmouth College, Harvard University, University of Pennsylvania, Princeton University and Yale University. The idea of an Ivy League school originated in the 1950s. At first, this concept had nothing to do with the academics of these schools, but the name of a sports league. Early schools often held some social and sports competitions, so they made recognized rules and elected the principals of the alliance schools. The earliest Ivy League schools were composed of Harvard, Yale, Columbia and Princeton. The Roman letter "four" with a y at the end of the word is ivy in English, so it comes from this. Since then, the scale of the alliance school has gradually expanded, and it has evolved into an Ivy League composed of eight famous universities.

It is also said that it is because the teaching buildings of early American colleges and universities are covered with ivy that they have this title. Anyway, now, "Ivy League School" has become synonymous with the top universities in America.
