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
Central Powers in World War I (the
Allies of World War I), or those who fought against the
Axis Powers in World War II (the
Allies of World War II). The term has also been used by the
United States Army to describe the countries that gave assistance to

More recently, the term "Allied forces" has also been used to describe the
coalition of the Gulf War, as opposed to forces the
Multi-National Forces in Iraq which are commonly referred to as "Coalition forces" or, as by the
George W. Bush administration,
"the coalition of the willing".
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.
A 2000 study in the ''
Journal of Conflict Resolution'' 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.
