Post a historical-based/themed series

Well, Baccano. It takes place in three different time lines, but, it is still historical. Just watch it, its great

Le Chevalier D'Eon <3

Emma: A Victorian Romance. This one's based in London during the late 1800's! Love this one!

Gintama also takes place in the Meiji restoration, but instead of Europeans paving their way to japan during the late edo period, it's aliens XD

Hakuouki is set in the Bakumatsu (late Edo) in the 1860s. The anime features the Shinsengumi, a samurai force founded to protect the Shogunate during a time of western opening of the ports. So a time of old vs. new

It is loosely based on the actual Shinsengumi members and is a reverse harem. Also has some yokai (demons) in the anime and vampiric tendencies here and there. So not complete historic but has a lot of the real people's names and ranks, and their battles.

BTW the series are in a confusing order because the second came out before the first and are long difficult names but the (storyline) order goes:
Hakuouki Reimeiroku
Hakuouki Shinsengumi Kitan
Hakuouki Hakkesturoku
Hakuouki Sekkaroku

There is Kuroshitsuji (Black Butler). It's a super good anime!!! It has three seasons.

Sengoku Basara
this anime is also based on Sengoku era in the history of feudal Japan.........

all characters in this anime were real especially the one in my pic his name is Date Masemune.

Date Masamune was a regional strongman of Japan's Azuchi-Momoyama period through early Edo period. Heir to a long line of powerful daimyo in the Tōhoku region, he went on to found the modern-day city of Sendai.

Born: September 5, 1567, Yonezawa, Yamagata Prefecture, Japan
Died: June 27, 1636

I have 2: The first is Inuyasha. One of the main characters, Kagome, switched between present and Feudal Japan. The other is Hetalia, the 1 pictured. Hetalia is all based off of world history.

Samurai Champloo is set in the Edo Era of Japan.
