Watch The Throne was a blockbuster album, spawning big singles ("Otis," "N*ggas In Paris"), an ambitious tour, and a fair amount of acclaim. The idea for the project began simply as EP, but quickly grew much bigger, involving a slew of big name producers (Hit-Boy, Jeff Bhasker, The Neptunes, Q-Tip, Mike Dean, RZA) and featured artists (Frank Ocean, The-Dream, Beyonce).

As gargantuan as the presentation became (down to its Riccardo Tisci-designed cover), it was always very clearly about its two leading men -- Jay Z and Kanye West. While their first equal-billing on an album, it was far from the first time the two had worked together, and their relationship now dates back over 15 years. We've put together a timeline of the two rappers, who would eventually refer to themselves as The Throne, in a new infographic. Read it below.
