In short
On December 25, 800, Pope Leo III crowned Charles of the Franks as Emperor of the Romans during Christmas Mass in St. Peter's Basilica in Rome. The act revived the imperial title in Western Europe for the first time in over three centuries and transformed Charlemagne from a powerful regional king into a figure claiming universal Christian authority.

Afterward
What followed
- 843 - Fragmentation of the Carolingian Empire. By the Treaty of Verdun, Charlemagne's grandson Louis II divided the empire among his three sons, creating roughly the territorial bases of modern France, Germany, and Italy. The unified empire lasted only a generation.
- 962 - Establishment of the Holy Roman Empire as a concept. Otto I of Saxony was crowned Emperor by Pope John XII, deliberately invoking Charlemagne's precedent. This created the formal institution that would persist, contested and reformed, until 1806.
- 1076 - Investiture Controversy begins. Pope Gregory VII and Emperor Henry IV clashed over who had the right to appoint bishops, a power struggle rooted in the ambiguity Leo III and Charlemagne left unresolved in 800. The conflict defined medieval church-state relations for centuries.
- 1165 - Charlemagne canonized. Pope Alexander III canonized Charlemagne, cementing his status as both a warrior-king and a saint. His relics became a pilgrimage site and his legacy a model for subsequent European rulers.
- 1804 - Napoleon crowns himself Emperor. Nearly 1,000 years later, Napoleon Bonaparte deliberately echoed Charlemagne's coronation by crowning himself in Notre-Dame, claiming direct succession to the Carolingian legacy. He even named his son the King of Rome.

The world it landed in
What was on the radio, the screen, and everyone's mind.
Same week, elsewhere
The year 800 falls outside the period of recorded music, film, or television. The cultural artifacts of Charlemagne's court were manuscripts, illuminated texts, and oral traditions preserved by scribes and monks. The Carolingian Renaissance was a literacy and learning movement, centered on the copying and preservation of classical Latin texts in monasteries and the palace school at Aachen, rather than a period of popular music or visual media as those categories are understood today.
