Spears were virtually ubiquitous throughout human history, adopted by cultures around the world as a basic weapon. In 221 BCE, the Chinese Assassin Wei Yu slew the first Emperor of China, Qin Shi Huang, with a spear. Until the advent of firearms, spears saw regular service with militaries, such as that of the Saracens during their assault on the Assassin citadel of Masyaf in 1176.
During the Renaissance, guards which employed pole weapons such as spears and halberds were commonly called Seekers. While the Italian Brotherhood of Assassins tended to forsake polearms for their impediment to freerunning, spears were favored by many prominent Templars of this era, infamous examples being the Turkmen renegade Shahkulu, Odai Dunqas, and Samila Khadim.
Though spears were gradually phased out in militaries by firearms like other melee weapons, as late as the French Revolution, they continued to see use among the Assassins such as those of the Parisian Brotherhood.
- In Assassin's Creed II and Assassin's Creed: Brotherhood, spears and halberds are classified as long weapons and cannot be purchased from any blacksmith shop. They can only be used by disarming them from Seekers or picking them up from the ground after killing a Seeker. Should the player character, Ezio Auditore da Firenze, break into a full sprint or freerun at any time, he will automatically drop the spear as he cannot equip a long weapon.
- Spears are absent from Assassin's Creed, but in Assassin's Creed: Revelations, some Templar knights who used the weapon are fought in the memory "The Mentor's Keeper", which chronologically took place before Assassin's Creed.
- It is possible for some guards to use the spear, including militia and Borgia captains. If they are disarmed, and the closest weapon on the ground is a spear, they will pick that up provided that no Seeker is alive nearby to take it as well.
- Borgia captains who used the spear has the running and action animations of the Seekers. Additionally, they can put the spear or halberd in their empty sheaths, but the spear will appear to be broken.
- In the non-canonical mobile version of Assassin's Creed II, a polearm called a "spear" by the game is part of the player's equipment, but it is technically a glaive, not a spear. Ezio Auditore uses it to assassinate the Templar Emilio Barbarigo.
- In Assassin's Creed: Unity, the spear features as a weapon that can be purchased and fully equipped for the first time.
