The Queen's sister, Princess Margaret, died in February 2002 and her mother died in March.
Because her father died 50 years ago, the Queen now has no-one left from the family she grew up with.
2002 began as a sad year for the Queen but there were also happy times. Millions of people helped celebrate the Golden Jubilee.
Prince William and his fiancee Kate Middleton
In 2003 the Earl and Countess of Wessex added a baby daughter to the Queen's family.
Then in 2010 TWO royal engagements were announced. Zara Philips announced her engagement to her ex-rugby player boyfriend Mike Tindall.
But the biggest royal news was the announcement of Prince William's wedding to Kate Middleton, to take place on April 29 2011.
