As a granddaughter of the monarch in the male line, Elizabeth's full style at birth was Her Royal Highness Princess Elizabeth of York. She was third in the line of succession to the throne, behind her uncle, Edward, Prince of Wales, and her father, the Duke of York. Although her birth generated public interest, she was not expected to become queen, as the Prince of Wales was still young and many assumed he would marry and have children of his own.[12] In 1936, when her grandfather,1 George, died and her uncle succeeded as Edward VIII, she became second in line to the throne after her father. Later that year, Edward abdicated after his proposed marriage to divorced socialite Wallis Simpson provoked a constitutional crisis.[13] Elizabeth's father became king and she became heiress presumptive, with the style Her Royal Highness The Princess Elizabeth.[14] If her parents had had a later son, she would have lost her position as heiress presumptive as her brother would have been heir apparent and above her in the lin of succession.
