War and Military Atlas
Claims this atlas currently marks as unsettled or as tested and found false. A debated fact is one scholars hold competing positions on; a debunked one has been checked against the record and found not to hold. Both are kept in view rather than quietly smoothed over, with the reasoning that put each one where it stands.

Wikipedia gives the tachi own dominance as the Koto period, stated as 900 to 1596; 900 marks the start of that period rather than a single invention year, and high-ranking samurai kept wearing the tachi after the later katana became the mainstream sword.

Wikipedia places voulge use primarily in 15th-century France, illustrated by its own cited 1455 manuscript image; the atlas own description spans the fourteenth and fifteenth centuries, so 1400 marks the turn of that period rather than one exact invention year.
