Sekigahara

Narrator:
That year, at dawn of the twenty-first day of the tenth month—the month without gods—the main armies clashed. It was in the mountains near Sekigahara, astride the North Road. By late afternoon, Toranaga had won the battle and the slaughter began.
Forty thousand heads were taken.

— “Shōgun” (1980)

The year is 1600 C.E.

The book and television mini-series are a fictionalized account of the events leading up to this historical battle which de facto unified Japan.
