Two of the same civilization's team bonuses do not stack, but a team bonus can stack with another bonus. It is also important to note that should a player be defeated or resigns, their team bonus remains active for their allies. However, In diplomacy games (with no locked teams), team bonuses do not affect allies. This is because team bonuses function as a technology that is researched at the beginning of the game, and as such, changing allies mid-game will not transfer the team bonus. A team bonus can be applied in a diplomacy game if players set their team at the beginning of the game.

While the Berber and Cuman unique technologies Kasbah and Cuman Mercenaries are not team bonuses (as the player or one of their allies has to pay for them), they share the property that they apply to the whole team. Another difference Kasbah has from team bonuses is that its effects stack if multiple teammates research them. For example, if two Berber teammates research Kasbah, their team's Castles will work 56.25% faster (instead of 25%).
Out of all 57 unique units in the game, three are available as team bonuses: the Condottiero, Genitour, and Imperial Skirmisher. These are often used to supplement lacking unit lines (for example Condottieri can make up for the Persians' lacking Militia line; Aztec Imperial Skirmishers surpass the Aztec Arbalester; and Turks as they lack Elite Skirmishers and have fantastic Genitours with their Sipahi technology.), or to cover a niche, such as a late Imperial Age trash game.
It should also be noted that although the bonuses are referred to as "team" bonuses, they do apply in 1v1 games. However, three of the team bonuses, the Bengali food from trading, the Portuguese free Cartography and the Spanish +25% gold from Trade Carts, are entirely useless in 1v1 games.
