Short answers, pulled from the story.
Queen Victoria reigned for 63 years and 216 days, from the 20th of June 1837 until her death on the 22nd of January 1901. Her reign was longer than any of her predecessors and constituted what became known as the Victorian era.
Queen Victoria married Prince Albert of Saxe-Coburg and Gotha on the 10th of February 1840, in the Chapel Royal of St James's Palace in London. Albert was her maternal first cousin, introduced to her by her uncle Leopold, King of the Belgians.
At least seven attempts were made on Queen Victoria's life across her reign. They include Edward Oxford in 1840, John Francis and John William Bean both in 1842, William Hamilton in 1849, Robert Pate in 1850, Arthur O'Connor in 1872, and Roderick Maclean in 1882.
Queen Victoria assumed the title Empress of India from the 1st of May 1876, following the passage of the Royal Titles Act 1876, which was promoted by Prime Minister Benjamin Disraeli. The new title was formally proclaimed at the Delhi Durbar on the 1st of January 1877.
Queen Victoria earned the sobriquet "grandmother of Europe" because her nine children married into royal and noble families across the continent. Of her and Albert's grandchildren, 34 survived to adulthood, and several carried the blood-clotting disease haemophilia B into the royal houses of Russia and Spain.
Queen Victoria died at Osborne House on the Isle of Wight on the 22nd of January 1901, aged 81. She had written instructions in 1897 specifying a military funeral with white rather than black colours; she was buried in a white dress and wedding veil, interred beside Prince Albert in the Royal Mausoleum at Frogmore.
