Who was Queen Elizabeth II's paternal grandfather?

George V (reigned 1910-1936) was the paternal grandfather of Queen Elizabeth II (born 1926). He was the grandson of Queen Victoria (reigned 1837-1901) and the son of Edward VII (reigned 1901-1910). When he was born in 1865, George was third in the line of succession after his father and his older brother, Albert Victor. He never expected to become king, but that changed following the death of his brother in 1892. When Edward VII died in 1910, George ascended the throne and served as King of the United Kingdom and Emperor of India until his death in 1936.

The eldest son of George V and his wife, Queen Mary, was Edward, who became king after his father’s death. A few months into his reign, Edward caused problems by proposing to Wallis Simpson, an American divorcée. As king, Edward was head of the Church of England, which at the time did not allow divorcées to remarry. As a result, King Edward VIII was forbidden to marry his fiancée. Yet, Edward's love for Simpson was greater than his desire to be king, so he abdicated in December 1936.

Edward was immediately succeeded by his younger brother Albert, Queen Elizabeth’s father, who chose to reign under the name King George VI. When he became king, he was already married to Lady Elizabeth Bowes-Lyon and had two daughters, Elizabeth and Margaret. Since he had no sons, his eldest daughter became queen when he died in 1952 at the age of 56.
