Baptism (from the Greek noun Βάπτισμα baptisma; itself derived from baptismos, washing) is a Christian rite of admission (or adoption), almost invariably with the use of water, into the Christian Church generally and also a particular church tradition. Baptism has been called a sacrament and an ordinance of Jesus Christ.

In some traditions, baptism is also called christening, but for others the word "christening" is reserved for the baptism of infants.

The New Testament reports that Jesus was baptized. The usual form of baptism among the earliest Christians was for the naked candidate to be immersed totally (submersion) or partially (standing or kneeling in water while water was poured on him or her). While John the Baptist's use of a deep river for his baptism suggests immersion, pictorial and archaeological evidence of Christian baptism from the 3rd century onward indicates that a normal form was to have the candidate stand in water while water was poured over the upper body. Other common forms of baptism now in use include pouring water three times on the forehead.

Annelies "Anne" Marie Frank ( pronunciation (help·info); 12 June 1929 – early March 1945) was one of the most discussed Jewish victims of the Holocaust. Her diary, has been the basis for several plays and films. Born in the city of Frankfurt am Main in Weimar Germany, she lived most of her life in or near Amsterdam, in the Netherlands. Born a German national, Frank lost her citizenship in 1941 when Nazi Germany passed the anti-Semitic Nuremberg Laws. She gained international fame posthumously after her diary was published. It documents her experiences hiding during the German occupation of the Netherlands in World War II.

The Frank family moved from Germany to Amsterdam in 1933, the year the Nazis gained control over Germany. By the beginning of 1940, they were trapped in Amsterdam by the Nazi occupation of the Netherlands. As persecutions of the Jewish population increased in July 1942, the family went into hiding in the hidden rooms of Anne's father, Otto Frank's, office building. After two years, the group was betrayed and transported to concentration camps. Anne Frank and her sister, Margot, were eventually transferred to the Bergen-Belsen concentration camp, where they both died of typhus in March 1945.
