"Blood royal" refers to the royal family or, more specifically, those members of the royal family by birth. This term is often used to denote lineage and descent from a hereditary monarch. People with "blood royal" are considered to be of noble birth and may hold certain privileges or titles within a kingdom.
For example, in the British monarchy, "blood royal" refers to descendants of Queen Victoria, the last British monarch to be crowned Queen of Hanover. This includes the current monarch, King Charles III, his siblings, and their children.
While "blood royal" may seem like a relic of the past, it remains an important concept in some monarchies today. In certain cultures, individuals with "blood royal" may be considered to have a special role in society, even if they do not hold a formal royal title.
