This was the name of kings of England, Serbia, and Poland, as well as ten popes. It was also borne by the first Christian king of Hungary (11th century), who is regarded as the patron saint of that country. More recent bearers include British physicist Stephen Hawking (1942-2018) and the American author Stephen King (1947-).
As an English given name, Christopher has been in general use since the 15th century. It became very popular in the second half of the 20th century, reaching the top of the charts for England and Wales in the 1980s, and nearing it in the United States.
In Denmark this name was borne by three kings (their names are usually spelled Christoffer), including the 15th-century Christopher of Bavaria who also ruled Norway and Sweden. Other famous bearers include Italian explorer Christopher Columbus (1451-1506), English playwright Christopher Marlowe (1564-1593), English architect Christopher Wren (1632-1723) and the fictional character Christopher Robin from A. A. Milne's Winnie-the-Pooh books.
