In 1912, the Ancient Order of Hibernians (A.O.H.) had become the most significant nationalist organisation in Ulster, a powerful auxiliary to the Irish Parliamentary Party, and a key part of what unionists feared would be Rome rule in a self-governed Ireland. However, while the A.O.H. is crucial to understanding nationalist Ulster and the border question, its reputation for fraternal secrecy and the apparent suddenness of its decline after the Irish Party's 1918 collapse has often seen it elude sustained academic enquiry. This article provides the first examination of the order from the Ulster crisis to the early decades of partition, drawing on the records of its governing Board of Erin. Scrutinising the grassroots and the leadership, this article interrogates dissension among Hibernians, the suspension of divisions and defections to Sinn Féin as the order reconciled proposals for Ulster exclusion with its traditional appeal. While Hibernians often found themselves part of a three-cornered conflict in the violent 1920s, the order ultimately survived on both sides of the border with regional variation important in estimating decline. Its persistence, therefore, illustrates something of the lived experience of partition and highlights important threads of continuity in a period of political and social upheaval.

1912 年，希伯尼安古骑士团 (AOH) 已成为阿尔斯特最重要的民族主义组织，是爱尔兰议会党的强大辅助力量，也是工会主义者担心罗马统治自治爱尔兰的关键部分。然而，虽然 AOH 对于理解民族主义阿尔斯特和边界问题至关重要，但它以兄弟般的保密而闻名，以及在爱尔兰党 1918 年垮台后明显突然衰落，它经常躲避持续的学术调查。本文根据艾琳管理委员会的记录，对从阿尔斯特危机到分治初期几十年的秩序进行了首次考察。审查基层和领导层，这篇文章询问希伯尼人之间的分歧，暂停分裂和叛逃至新芬党，因为该命令调和了将阿尔斯特排除在外的提议与其传统吸引力。虽然在 1920 年代的暴力冲突中，希伯尼亚人经常发现自己是三场冲突的一部分，但该命令最终在边界两侧幸存下来，地区差异对估计衰退很重要。因此，它的持久性说明了分裂的一些生活经验，并突出了政治和社会动荡时期连续性的重要线索。
