Originally Answered: Queen Elizabeth timeline?
I assume you can use events affecting her before she became Queen?
1536 - her mother, Anne Boleyn, was beheaded for witchcraft, adultery and treason (adultery was treason in a queen). Elizabeth was only (almost) three at the time, but it may have affected her greatly
1542 - Mary, Queen of Scots was born in Linlithgow, Scotland. This Queen was to have a major effect on Elizabeth's reign
1547 - Elizabeth's father, Henry VIII, dies, leaving her younger half-brother, Edward, as King. Elizabeth is sent to live with her stepmother (Henry's sixth and last wife), Katherine Parr, and Katherine's husband, Thomas Seymour. Thomas played some unsuitable games with young Elizabeth, which may have affected her. She was sent away, and Thomas was later executed.
1553 - Edward VI (her brother) dies and Lady Jane Grey is manipulated onto the throne. After nine days, Elizabeth's half-sister Mary takes her rightful place as Queen, which spells the beginning of a difficult time for Elizabeth as Mary is a devout Catholic who wants Elizabeth to embrace the Catholic faith
1554 - Thomas Wyatt leads a rebellion against Mary; Mary suspects Elizabeth of involvement and imprisons her in the Tower of London for two months. This is a very fearful time for her; she is later released and held at Woodstock
1558 - Mary dies, and Elizabeth is informed she is now Queen. Her fear has ended, and she says in Latin, "This is the Lord's doing and it is marvellous in our eyes"
1566 - the son of Mary, Queen of Scots and Henry, Lord Darnley, is born. He will be Elizabeth's heir to the throne of England as she will have no children
1568 - Mary, Queen of Scots abdicates and flees to England where Elizabeth keeps her imprisoned as a Catholic threat to her throne
1570 - Elizabeth is excommunicated from the Catholic Church
1584 - Sir Walter Raleigh receives the patent to explore and settle in North America
1586 - The Babbington Plot , a conspiracy against Elizabeth I involving Mary Queen of Scots.
July 1: Treaty of Berwick - Queen Elizabeth and King James VI (Mary's son) of Scotland form a league of amity
October 25: Mary Queen of Scots is convicted of involvement in the Babbington plot
1587 - February 8: Execution of Mary Queen of Scots
War with Spain which continues until 1603
April 19: Sir Francis Drake destroys the Spanish fleet at Cadiz
1588 - The Spanish Armada of 132 ships is defeated by the English fleet of 34 ships and 163 armed merchant vessels led by Lord Howard of Effingham, Sir Francis Drake, and Sir John Hawkins
September 4: her great life-long friend Robert Dudley dies
1601 - another of her favourites, the Earl of Essex, is executed for rebelling against her. Elizabeth never gets over the loss of her friends
1603 - early March, Elizabeth catches a chill while out walking. (This leads to her death)
