Final answer:
The British monarchy succession from George V to Elizabeth II went through pivotal changes: George V was succeeded by Edward VIII, who abdicated, leading to George VI's reign. George VI was then succeeded by his daughter, Elizabeth II.
Step-by-step explanation:
The succession of George V, Edward VIII, and George VI to the British throne was an important part of early 20th-century history, culminating in the ascension of Elizabeth II. George V was succeeded by his son, Edward VIII, in 1936. However, Edward VIII abdicated the throne the same year to marry Wallis Simpson, a divorced American woman. This led to George V's second son, George VI, taking the throne.
George VI, who was the father of the current queen, reigned until his death in 1952, leaving the crown to his eldest daughter, Elizabeth II, who has been the monarch since then and represents the continuation of the Windsor dynasty.
Monarchy in Britain is based on the practice of dynastic succession. This has evolved over time from a system where primogeniture and close male lineage were key, to the current rules, which allow for a more gender-equal line of succession. The story of Elizabeth II's ascension to the throne is emblematic of this historical lineage and the fluid changes within the British monarchy.
