British monarchy succession

British monarchy succession is governed by laws that determine who becomes the next monarch, primarily based on descent, legitimacy, and religion. The current system, established by the Succession to the Crown Act 2013, prioritizes the oldest child of the monarch, regardless of gender. When the reigning monarch dies or abdicates, the throne passes to their eldest child, then to that child's descendants in order of birth. If there are no children, the crown passes to the monarch's siblings and their descendants, following a specific order. This process ensures a clear, constitutional continuation of the monarchy.
