Great Moravia was one of the first proto-states in East Central Europe. During the ninth century, Moravian settlements underwent rapid growth, development, and population increases. This study presents a first insight into early medieval population mobility in the area by investigating one of its major agglomerations and religious centres, the Mikulčice-Valy stronghold. According to strontium isotope analysis of human tooth enamel, 13–19% of 123 analysed individuals fall outside the estimated local ⁸⁷Sr/⁸⁶Sr ranges and represent migrants from at least three distinct areas. Furthermore, human ⁸⁷Sr/⁸⁶Sr ratios are shifted in comparison to faunal references, which could indicate a greater rate of migration from isotopically similar areas. No evidence supporting the presumed higher mobility of elite females was found, but immigration is more prevalent among elites, with an apparent lack of non-elite males among the non-locals. Possible factors contributing to mobility are questioned and might offer directions for future studies.

大摩拉维亚是东欧中部最早的原始国家之一。在九世纪，摩拉维亚的定居点经历了快速的增长，发展和人口增长。这项研究通过调查该地区的主要集聚地和宗教中心Mikulčice-Valy要塞，首次了解了该地区的中世纪中世纪人口流动性。根据对人类牙釉质的锶同位素分析，在123位分析的个体中，有13–19％的人不在估计的本地⁸⁷ Sr / ⁸⁶ Sr范围内，并且代表了至少三个不同区域的移民。此外，人类⁸⁷ Sr / ⁸⁶与动物参考相比，Sr比率发生了变化，这可能表明从同位素相似区域迁移的比率更高。没有证据支持推测的精英女性更高的流动性，但是移民在精英人群中更为普遍，在非本地人中显然缺乏非精英男性。人们质疑可能导致流动性的因素，并可能为将来的研究提供指导。
