The Mandalorian just added a new "Mandalore" to Star Wars canon with the mention of Mandalore the Great. "Mandalore" is a title given to multiple figures in the Star Wars mythos. Some existed thousands of years before the Skywalker saga. The live-action Disney+ series features a Mandalorian in the protagonist role, and through his stories viewers are gaining new insight into this unique group of warriors.
The Mandalorian season 1 finale revealed much about the mysterious background of the titular hero, his people, the Mandalorians, and their culture. When Mando (Pedro Pascal), Greef Karga (Carl Weathers), and Cara Dune (Gina Carano) are forced into a tense standoff with the show's villain, Moff Gideon (Giancarlo Esposito), secrets about Mando's past began to emerge, including the reveal of the Mandalorian's real name and the Death Watch's involvement in his rescue. It was also confirmed by Mando that the Mandalorians were never a race, but a creed.
A conversation with the Mandalorian Armorer dropped a few more details about their history. When the Armorer was told of Baby Yoda's Force powers, she recognized their significance and told Mando of a story from "eons past" about a battle between Mandalore the Great and the Jedi, who the Armorer identified as an "order of sorcerers". There are several characters in Mandalorian history known by the name Mandalore, but as of yet there has been no one called "Mandalore the Great".
In the past, "Mandalore" has been used as a title for the warriors who have led the Mandalorian people. The name has been passed down from leader to leader from generation to generation, beginning with Mandalore the First. This is similar to how Caesar's name was used in ancient Roman history. After the rule of Julius Caesar, the name "Caesar" was carried by several Roman emperors as an honorific title.
Other notable Mandalores in the planet's rich history include Mandalore the Ultimate, Mandalore the Vindicated, and Mandalore the Avenger. The list goes on. Jango and Boba Fett have even assumed the title in the non-canon books and comics. For the most part, Mandalorians don't have a strong presence in the films, so their appearances are largely limited to the Star Wars Expanded Universe and video games like Star Wars: Knights of the Old Republic. The Mandalorian has now added a new version to the canon, and it's worth wondering if his contribution to Mandalorian history will be explored later. If The Mandalorian season 2 delves further into the ancient conflict between the Jedi and the Mandalorians, Mandalore the Great may receive a deeper backstory and a proper timeline, since it was never specified when he existed.
