Queen Elizabeth makes history Wednesday, officially becoming Britain's longest reigning monarch.
The Queen has held the throne for 63 years. Queen Victoria, Elizabeth's great, great grandmother, was the previous record-holder, as she held the throne from 1837 to 1901.
At the time of her birth, Queen Elizabeth was not expected to take the throne. However, her uncle renounced the throne to marry a divorced American socialite. Hence, Elizabeth's father became King with Elizabeth next in line.
The Queen has broken new ground during her reign for the British monarchy during many of her overseas visits.
