Which monarch was crowned 400 years before Queen Elizabeth II?

Mary I became Queen of England in July 1553 which was 400 years prior to Elizabeth II becoming Queen on 2 June 1953.

Mary I (18 February 1516 – 17 November 1558) was the Queen of England and Ireland from July 1553 until her death. Her executions of Protestants led to the posthumous sobriquet "Bloody Mary".

She was the only child of Henry VIII by his first wife Catherine of Aragon to survive to adulthood. Her younger half-brother Edward VI (son of Henry and Jane Seymour) succeeded their father in 1547.

Mary is remembered for her restoration of Roman Catholicism after her half-brother's short-lived Protestant reign. During her five-year reign, she had over 280 religious dissenters burned at the stake in the Marian persecutions. After her death in 1558, her re-establishment of Roman Catholicism was reversed by her younger half-sister and successor Elizabeth I, daughter of Henry and Anne Boleyn.
