Pope John XIX crowns Conrad II as Holy Roman Emperor.

Pope John XIX, born Roman of Tusculum, was the Bishop of Rome and ruler of the Papal States from 1024 to his death. He belonged to the family of the powerful Counts of Tusculum, succeeding his brother, Benedict VIII. Papal relations with the Patriarchate of Constantinople soured during John XIX's pontificate. He was a supporter of Emperor Conrad II and patron of the musician Guido of Arezzo.

Conrad II, also known as Conrad the Elder and Conrad the Salic, was the emperor of the Holy Roman Empire from 1027 until his death in 1039. The first of a succession of four Salian emperors, who reigned for one century until 1125, Conrad ruled the kingdoms of Germany, Italy and Burgundy.

The Holy Roman Emperor, originally and officially the Emperor of the Romans during the Middle Ages, and also known as the Roman-German Emperor since the early modern period, was the ruler and head of state of the Holy Roman Empire. The title was held in conjunction with the title of King of Italy from the 8th to the 16th century, and, almost without interruption, with the title of King of Germany throughout the 12th to 18th centuries.
