George V belonged to the House of Windsor (Saxe-Coburg-Gotha). Born in 1865, he ascended to the throne in 1910 and died in 1936. He was preceded as monarch by Edward VII and was succeeded by Edward VIII.
George was born at Marlborough House in London, the second son of the future Edward VII. As Prince George Frederick Ernest Albert, he began his career as a cadet of the Royal Navy at the age of 12. In January, 1892, George became heir apparent to the throne on the death of his older brother and in the following year was promoted to captain in the Royal Navy. He married his second cousin, Princess Victoria Mary, daughter of the Duke and Duchess of Teck in the same year.
On the ascension of his father, Edward VII, George became Duke of Cornwall and later was made Prince of Wales. The navy made him a rear admiral.
Reaching the throne in 1910, George made history as the first reigning monarch of Britain to visit his overseas dominion. He was active on behalf of his country during World War I. He died in 1936 after a brief illness.
