When did Penn become an Ivy League?

<p>I think that every other Ivy League school started off as a divinity school, or at least was religiously affiliated. Penn was the first US college set up specifically to be independent of religion by Ben Franklin, so that’s probably why it got the name University of Pennsylvania, as opposed to Franklin University or something. And I think also that all the other ivy league school names come from the founders of the schools, who were religious men. I might be wrong on this though. And yeah its funny how the original football league is now like Division III status and the bottom rung when it comes to college football. Smart people invented football, then realized how dangerous it is, haha.</p>
