An alliance is a relationship among
people, groups, or
states that have joined together for mutual benefit or to achieve some common purpose, whether or not explicit agreement has been worked out among them.
Members of an alliance are called allies. Alliances form in many settings, including
political alliance
A political group is a group consisting of political parties or legislators of aligned ideologies. A technical group is similar to a political group, but with members of differing ideologies.

military alliances, and
business alliances. When the term is used in the context of
war or armed struggle, such associations may also be called allied powers, especially when discussing
World War I or
World War II.
A formal
military alliance is not required for being perceived as an ally—
co-belligerence, fighting alongside someone, is enough. According to this usage, allies become so not when concluding an alliance treaty but when struck by war.
When spelled with a capital "A", "Allies" usually denotes the countries who fought together against the

Effects
Scholars are divided as to the impact of alliances. Several studies find that defensive alliances deter conflict. One study questions these findings, showing that alliance commitments deterred conflict in the prenuclear era but has no statistically meaningful impact on war in the postnuclear era. Another study finds that while alliance commitments deter conflict between sides with a recent history of conflict, alliances tend to provoke conflicts between states without such a history.

'' found that allies fulfill their alliance commitments approximately 75% of the time. Most research suggests that democracies are more reliable allies than non-democracies. A 2004 study did however question whether alliance commitments by democracies are more durable. A 2018 study updated and extended the data from the 2000 ''Journal of Conflict Resolution'' study and found that allies only fulfill their commitments about 50% of the time from 1816 to 2003.
According to the study, "States honored their alliance commitments 66% of the time prior to 1945 but the compliance rate drops to 22% from 1945 to 2003. Moreover, the rates of fulfillment for defense pacts (41%) and nonaggression pacts (37%) are dramatically lower than offensive alliances (74%) and neutrality agreements (78%)."
One of the most profound effects of alliances can be seen in technological innovation, due to conduits of knowledge flows that are open between allies but closed between rivals.
