本文从小国寡民的特性、地理条件、族缘与宗教、安全利益与霸权、波斯入侵与泛希腊主义五个方面分析了古希腊城邦同盟形成的原因。实际上,每个城邦同盟往往不是在某个因素单独作用下形成,而是几个因素共同作用的结果。虽然影响同盟形成的原因各有不同,但是最根本的一点,结盟的城邦都是以维护本邦利益为出发点,最终目的是保卫或加强本城邦的利益。 This article analyzes the reasons for the formation of the ancient Greek city-states alliance from the characteristics of the countrymen, the geographical conditions, ethnic origin and religion, security interests and hegemony, the Persian invasion and Pan-Greekism. In fact, each city-state alliance is often not formed under the influence of a single factor, but as a result of a combination of several factors. Although the reasons for influencing the formation of the allies are different, the most fundamental point is that alliances and alliances are based on the interests of the state, with the ultimate aim of defending or strengthening the interests of the city.
