What feudal domain did William Henry Harrison Seeley fight against?
Shimonoseki Campaign The Shimonoseki Campaign (Japanese: 下関戦争/馬関戦争 , Hepburn: Shimonoseki Sensō/Bakan Sensō , lit. "Shimonoseki War") refers to a series of military engagements in 1863 and 1864, fought to control Shimonoseki Straits of Japan by joint naval forces from Great Britain, France, the Netherlands and the United States, against the Japanese feudal domain of Chōshū, which took place off and on the coast of Shimonoseki, Japan.
Mesne lord A mesne lord was a lord in the feudal system who had vassals who held land from him, but who was himself the vassal of a higher lord. A mesne lord did not hold land directly of the king, that is to say he was not a tenant-in-chief. His subinfeudated estate was called a "mesne estate" or "Afterlehen" in the Holy Roman Empire. He was thus an intermediate or "middle" tenant, which status is reflected in the medieval French word "mesne", in modern French "moyen".
