context: According to Ptolemy and Pliny the Elder, the island's residents called the island Albion. The Romans called their province on the island Britain. The name is believed to be derived from British Celtic descent. After the destruction of the Roman Empire, the name was forgotten. In the early Middle Ages Albion returned to use. Hundreds of years later, in the Celtic Medieval period, the continent's inhabited areas began to be called Brittany (Little Britain) and the island Great Britain, in French: Brittany and Grande Brittany. In 1604, King James of England and Scotland (James VI of Scotland since 1567, James I of England since 1603) called himself King of the United Kingdom, perhaps to avoid his awkward title. The title "King of Great Britain" became official in 1707 as the kingdoms united. Since 1801, rulers have been rulers of the United Kingdom of Great Britain and (Northern) Ireland.
