But considering that Tobirama became Hokage after Hashirama died, and Hashirama was stated to have died during a war. It's only logical that it was the first war, especially since Tobirama died during that war as well. The First Shinobi World War was the war Tobirama died in and the one Hiruzen became Hokage in, the Second Shinobi World War was during the Sannin Era where Jiraiya, Orochimaru, and Tsunade earned their names and fame. The Third Shinobi World War was during Minato's time and was the war when Obito "died" and Kakashi obtained his Sharingan as a child. With the Fourth Shinobi World War being the last and most recent one that we all know about.
