Salic law is a legal principle that originated in the early medieval period, primarily associated with the Franks. It stipulates that inheritance of the throne or property cannot pass through female lines, meaning that women are excluded from succession. This law was significant in shaping the royal lineage in various European monarchies. The most notable application of salic law occurred in France, where it influenced the succession of the French monarchy. It was a key factor in disputes over royal succession, particularly during the Hundred Years' War, as it determined who could rightfully claim the throne based on male lineage.
