Furthermore, will the British monarchy end?
Ultimately, the fate of the monarchy is difficult to predict. This time last year, even royal experts couldn't have estimated that three members of the family would have resigned by the beginning of 2020.
Subsequently, question is, what would happen if the British monarchy was abolished? Abolishing the monarchy would also create a position for an elected head of state, which can mean making the prime minister the head of state, or creating a separate position like a chancellor who would be chosen by parliament after a government is formed.
Keeping this in consideration, is the British monarchy still relevant?
The monarchy thus ceased to be an exclusively British institution, although it is often still referred to as "British" for legal and historical reasons and for convenience. The monarch became separately monarch of the United Kingdom, monarch of Canada, monarch of Australia, and so forth.
When did England stop being a monarchy?
Eventually there was a major rift with Charles I, who really wanted all the powers of an absolute monarch. This led to the English Civil War in 1642, the execution of Charles, and the abolition of the monarchy entirely. It was restored in 1660.
