To any­one unfa­mil­iar with the his­to­ry of Islam, it comes as some­thing of a shock that it got start­ed less than a mil­len­ni­um and a half ago. In that rel­a­tive­ly short span of time, Islam has become the world’s sec­ond-largest reli­gion, a fact that becomes more under­stand­able when you see the run­ning start to which it got off visu­al­ized in the video above. Cre­at­ed by Ollie Bye — pre­vi­ous­ly fea­tured here on Open Cul­ture for his car­to­graph­i­cal ani­ma­tions of the rise and fall of the British Empire, the spread of writ­ing, and the his­to­ry of the world — it depicts the spread of Islam, which began in earnest after the death of its founder, the prophet Muham­mad, in the year 632, and whose lega­cy is the “Mus­lim world” as we know it today.

“By con­quest and con­ver­sion, the new reli­gion spread quick­ly west­wards through the ter­ri­to­ries of the Byzan­tine empire,” says the Vic­to­ria and Albert Muse­um’s page on lux­u­ry objects of the peri­od. “By the 640s, Mus­lim forces were advanc­ing across North Africa, con­quer­ing Sici­ly in 652 and the Iber­ian Penin­su­la in 711.”

Let’s pause to give that achieve­ment due con­sid­er­a­tion: Islam over­took Spain just a cen­tu­ry after its foun­da­tion, a con­quer­ing speed that puts the Roman Empire in the shade. (The Mus­lims also man­aged to get the upper hand of the Per­sians, who’d pre­sent­ed such a stiff chal­lenge to not just the Romans but the Greeks before them.) “By the ear­ly 8th cen­tu­ry, Islam­ic ter­ri­to­ries had almost encir­cled the Mediter­ranean.“ ‘

“Dur­ing this time Mus­lim rulers, sol­diers, traders, Sufis, schol­ars, poets and archi­tects all con­tributed to the shap­ing of dis­tinc­tive Islam­ic cul­tures,” says the site of Har­vard’s Plu­ral­ism Project. “Across the wide-reach­ing Islam­ic world, tran­sre­gion­al Islam­ic cul­ture mixed with local tra­di­tions to pro­duce dis­tinc­tive forms of state­craft, the­ol­o­gy, art, archi­tec­ture, and sci­ence.” (Nor should we neglect the delights of Moor­ish cui­sine.) This Islam­ic Gold­en Age, like all gold­en ages, even­tu­al­ly came to an end. The cen­ter of civ­i­liza­tion had shift­ed unde­ni­ably by the time of the Euro­pean Renais­sance — which, accord­ing to the Plu­ral­ism Project, may nev­er have tak­en place “with­out the cre­ativ­i­ty and myr­i­ad achieve­ments of Mus­lim schol­ars, thinkers, and civ­i­liza­tions.” And giv­en that Islam remains the world’s fastest-grow­ing major reli­gion by births, it sure­ly has­n’t exert­ed the last of its glob­al influ­ence just yet.

Pope Fran­cis, who’s been head of the Catholic Church for a decade now, is offi­cial­ly Pon­tiff num­ber 266. But if you scroll through Wikipedi­a’s list of popes, you’ll see quite a few entries with­out num­bers, their rows cast in a dis­rep­utable-look­ing dark­er shade of gray. The pres­ence of sev­er­al such unof­fi­cial Popes usu­al­ly indi­cates par­tic­u­lar­ly inter­est­ing times in the his­to­ry of the Church, and thus the his­to­ry of West­ern civ­i­liza­tion itself. The new TED-Ed video above, writ­ten by medieval his­to­ry pro­fes­sor Joëlle Rol­lo-Koster, tells of the only peri­od in which three popes vied simul­ta­ne­ous­ly for legit­i­ma­cy. This was The West­ern Schism — or the Papal Schism, or the Great Occi­den­tal Schism, or the Schism of 1378.

How­ev­er one labels it, “the ori­gins of this papal predica­ment began in 1296, when France’s King Philip IV decid­ed to raise tax­es on the church.” So begins the nar­ra­tor of the video, which ani­mates the his­tor­i­cal scenes he describes in the style of a medieval illu­mi­nat­ed man­u­script. (It includes many amus­ing details, though I haven’t man­aged to spot any aggres­sive rab­bits or snails, to say noth­ing of butt trum­pets.) Pope Boni­face VIII, the Church’s leader at the time, respond­ed with the Unam Sanc­tam, “a rad­i­cal decree assert­ing the pope’s total suprema­cy over earth­ly rulers.” The clash between the two result­ed in the death of Boni­face, who was even­tu­al­ly replaced in 1305 by Clement V.

As “a French diplo­mat seek­ing peace in the war between Eng­land and his home­land,” Clement strate­gi­cal­ly moved the seat of the papa­cy to Avi­gnon. Sev­en popes lat­er, the papa­cy moved back to Italy — not long before the death of Gre­go­ry XI, the Pon­tiff who moved it. Out of the chaot­ic process of select­ing his suc­ces­sor came Pope Urban VI, who turned out to be “a reformer who sought to lim­it the car­di­nals’ finances.” Those car­di­nals then “denounced Urban as a usurp­er” and elect­ed Pope Clement VII to replace him. But Urban refused to relin­quish his posi­tion, and in fact “entrenched him­self in Rome while Clement and his sup­port­ers returned to Avi­gnon.”

This began the schism, split­ting West­ern Chris­ten­dom between the cap­i­tals of Avi­gnon and Rome. Each cap­i­tal kept its line going, replac­ing popes who die and per­pet­u­at­ing the sit­u­a­tion in which “Euro­pean rulers were forced to choose sides as both popes vied for spir­i­tu­al and polit­i­cal suprema­cy.” Only in 1409 did a group of car­di­nals attempt to put an end to it, elect­ing a new pope them­selves — who went unrec­og­nized, of course, by the exist­ing popes in Rome and Avi­gnon. The schism went on for near­ly 40 years, under­scor­ing the allit­er­a­tive truth that “even those who are sup­posed to be pious are prone to pet­ty pow­er strug­gles.” Most popes, like any fig­ures of pow­er, must feel lone­ly at the top — but that’s sure­ly bet­ter than when it’s too crowd­ed there.
