Alleanze

Alleanze are formal agreements between states, international organizations, or other actors to cooperate in pursuit of shared interests. They are typically enshrined in a treaty or pact that specifies objectives, obligations, duration, and governance mechanisms, such as decision-making processes and dispute settlement. The plural alleanze is Italian for such arrangements.

Alliances can be categorized by purpose: security and defense alliances commit members to consult or come to each other’s aid in case of aggression; economic and political alliances coordinate trade, investment, regulatory standards, or diplomatic positions; and scientific or cultural alliances facilitate cooperation across fields. Some alliances are long-term and institutionalized, while others are more informal partnerships or blocs.

In international relations, alliances are designed to deter aggression, balance power, and increase collective influence. They can contribute to stability by clarifying expectations, but can also increase risks of escalation or entrapment if member interests diverge or a crisis arises.

Examples: historically, the Triple Alliance (1882) and the Triple Entente (1907) shaped Europe’s balance of power prior to World War I. The North Atlantic Treaty Organization (NATO), established in 1949, remains the most prominent security alliance. The Warsaw Pact (1955–1991) served as the Soviet-led counterpart in the Cold War. In the contemporary era, security pacts such as AUKUS illustrate modern defense cooperation, while economic alliances and unions—such as the European Union’s internal market and its security policy—demonstrate how alliances span multiple domains.
