Why did Mary I succeed Lady Jane Grey?
Deposition of Jane; Mary's statutory right upheld with popular and noble support. First cousins once removed — Mary was Henry VIII's daughter; Jane was his sister's granddaughter.
The short answer
Mary rallied support in East Anglia, the Privy Council changed sides, and she was proclaimed queen in London on 19 July 1553. Her claim rested on Henry VIII's will and the Third Succession Act, which placed her next after Edward. Jane, never crowned, was imprisoned and executed in 1554.
