公元前8-7世纪,斯巴达对外扩张,征服了美塞尼亚,逐步建立希洛制度,国力日益增强,随之成为全希腊的霸主。但自公元前5世纪初期开始,斯巴达公民人数日趋减少,从而对斯巴达霸权地位产生不利影响。斯巴达公民减少的原因大致有两方面,即战争、自然灾害。 In the 8th and 7th centuries BC, Sparta expanded its presence abroad, conquered the United States and gradually established the Hilo system. With its growing national strength, Sparta became the overlord of all Greece. However, since the early 5th century BC, the number of Spartan citizens has been declining, which has an adverse effect on the hegemony of Sparta. There are two main reasons for the decrease of Sparta citizens: war and natural disasters.
