History Mode

History Mode is one of the new modes that was created for Fire Emblem Warriors.

Description
In this mode, the player relives various battles from previous games in the Fire Emblem series. The player will be seen on a map with a main Lord, with sprites taken from Awakening and Fates. There are various enemies spread throughout the board, some of which will block other enemies, requiring other battles to take place as well. These battles each have a theme, similar to battles in Adventure Mode from Hyrule Warriors.

Battle Types
Battles have rewards, with some having additional rewards that require the player to complete the battle with an S-Rank. Additionally, some levels have two of Anna's Mementos.
 * Targeted Elimination (Defeat certain captains to unlock the enemy fort).
 * Ally Rescue (Save allies to unlock the enemy fort)
 * Fort Siege (Capture specific forts to unlock the enemy fort)
 * Fort Defense (Defeat certain captains and keep forts under control to unlock enemy fort)
 * Pincer Escape (Similar to Targeted elimination, but facing two armies)
 * Shadow Elimination (Defeat Mages and Shadow Clones to unlock Enemy fort)
 * Rendezvous Disruption (Similar to Targeted Elimination, but if specific units meat up with Captains, they'll be strengthened)
 * Recruitment Battle (An NPC must be escorted to recruit Rouge forces. These forces must be defeated or recruited to unlock enemy fort)
 * Arena (The player must face a series of increasingly difficult battles. They must survive three in order to get out earliest)
 * Timed Onslaught (The player must defeat as many enemies as possible within the time limit)
 * Timed Attack (The player must defeat a certain amount of enemies within the time limit)
 * Gold Rush (Similar to Timed Onslaught, but gold is more common)

Some levels have restrictions, requiring the player use characters of a certain movement type, weapon, gender (barring Robin and Corrin), or game of origin.

The player must defeat a specific enemy to clear the map.

Completing the first two maps will unlock Female Robin and Male Corrin costumes, respectively. Clearing the third map unlocks Exalted Falchion's scroll, and clearing the last two maps unlocks Lyndis and Celica.

Space-Time Distortions
Upon completing the map, Outrealm Portals will appear on the map. Upon meeting special requirements (defeating the boss, defeating the boss with an S Rank, clearing all battles, and clearing all battles with an S-Rank), as well as advancing far enough in story mode, characters from across the games will appear. These will offer high leveled missions that grant the player great rewards, including scrolls and opus that will increase the Personal Weapons' power.

The conversations of these distortions are modified conversations from previous Fire Emblem games, including games that aren't featured in the game, such as the Tellius games.

Substitute Characters
Throughout the History mode maps, the scenarios retell the previous Fire Emblem stories. However, some characters are replaced for either not appearing in Warriors or randomly.

Anna's Mementos
Throughout both Story and History Mode, Anna can be visited during battles to unlock mementos (similar to the Gold Skullutas in Hyrule Warriors). Obtaining Mementos adds pieces towards in-game illustrations. If all the pieces of an illustration are collected, an incredibly high leveled mission is obtained. These missions are the story of the maps compressed into one battle, with Anna and her sisters joining the enemy.

Clearing any of these battles will instantly unlock Anna.
