Elizabeth was the daughter of Henry VIII and Anne Boleyn, his second wife, who was executed two-and-a-half years after Elizabeth's birth. Anne's marriage to Henry VIII was annulled, and Elizabeth was declared illegitimate. Her half-brother, Edward VI, ruled until his death in 1553, bequeathing the crown to Lady Jane Grey and ignoring the claims of his two half-sisters, Elizabeth and the Roman Catholic Mary, in spite of statute law to the contrary. Edward's will was set aside and Mary became queen, deposing Lady Jane Grey. During Mary's reign, Elizabeth was imprisoned for nearly a year on suspicion of supporting Protestant rebels.
In 1558, Elizabeth succeeded her half-sister to the throne and set out to rule by good counsel. She depended heavily on a group of trusted advisers, led by William Cecil, 1st Baron Burghley. One of her first actions as queen was the establishment of an English Protestant church, of which she became the Supreme Governor. This Elizabethan Religious Settlement was to evolve into the Church of England. It was expected that Elizabeth would marry and produce an heir to continue the Tudor line; she never did, despite numerous courtships. She was eventually succeeded by her first cousin twice removed, James VI of Scotland. She had earlier been responsible for the imprisonment and execution of James's mother, Mary, Queen of Scots.
In government, Elizabeth was more moderate than her father and half-siblings had been. One of her mottoes was "video et taceo" ("I see but say nothing"). In religion, she was relatively tolerant and avoided systematic persecution. After the pope declared her illegitimate in 1570 and released her subjects from obedience to her, several conspiracies threatened her life, all of which were defeated with the help of her ministers' secret service. Elizabeth was cautious in foreign affairs, manoeuvring between the major powers of France and Spain. She only half-heartedly supported a number of ineffective, poorly resourced military campaigns in the Netherlands, France, and Ireland. By the mid-1580s, England could no longer avoid war with Spain. England's defeat of the Spanish Armada in 1588 associated Elizabeth with one of the greatest military victories in English history.
As she grew older, Elizabeth became celebrated for her virginity. A cult grew around her which was celebrated in the portraits, pageants, and literature of the day. Elizabeth's reign became known as the Elizabethan era. The period is famous for the flourishing of English drama, led by playwrights such as William Shakespeare and Christopher Marlowe, and for the seafaring prowess of English adventurers such as Francis Drake. Some historians depict Elizabeth as a short-tempered, sometimes indecisive ruler, who enjoyed more than her share of luck. Towards the end of her reign, a series of economic and military problems weakened her popularity. Elizabeth is acknowledged as a charismatic performer and a dogged survivor in an era when government was ramshackle and limited, and when monarchs in neighbouring countries faced internal problems that jeopardised their thrones. After the short reigns of her half-siblings, her 44 years on the throne provided welcome stability for the kingdom and helped forge a sense of national identity.
Elizabeth was born at Greenwich Palace and was named after both her grandmothers, Elizabeth of York and Elizabeth Howard. She was the second child of Henry VIII of England born in wedlock to survive infancy. Her mother was Henry's second wife, Anne Boleyn. At birth, Elizabeth was the heir presumptive to the throne of England. Her older half-sister, Mary, had lost her position as a legitimate heir when Henry annulled his marriage to Mary's mother, Catherine of Aragon, to marry Anne, with the intent to sire a male heir and ensure the Tudor succession. She was baptised on 10 September 1533; Archbishop Thomas Cranmer, the Marquess of Exeter, the Duchess of Norfolk and the Dowager Marchioness of Dorset stood as her godparents. A canopy was carried at the ceremony over the three-day old child by George Boleyn, Viscount Rochford, John Hussey, 1st Baron Hussey, Lord Thomas Howard, and William Howard, 1st Baron Howard of Effingham.
