Alliances are an important aspect of The Hunger Games, as tributes ensure their survival by having allies watch their back in the arena. Allies usually share food and weapons and help each other stay alive. Tributes that are unlikely to receive sponsors and have no food have to depend on allies to help them. Alliances generally break apart near the end of the Games so the members are not forced to kill each other after. A common alliance in the Games is the one between the Career Tributes of Districts 1, 2 and 4 (in The Hunger Games film, it is only Districts 1 and 2 who form the Career alliance) who work together to take down every other tributes until their alliance is all that remains, and then they rip each other apart, much to the pleasure of the Capitol.
Alliances are most often formed between tributes that are from the same district.
10th Hunger Games
Coriolanus Snow is surprised when he learns about the alliance between the tributes from District 12, suggesting that alliances weren't formed in prior Games. This could possibly be a result of the tributes spending time together before the Games, as in previous years, the tributes were immediately transported from the reaping to the arena. The new nature of the Capitol Arena also provides new opportunities for alliances, as the landscape of the arena is reshaped following a bombing.

The rest stayed loyal to their promise, willing to give their life at any moment.
