海西女真葉赫、哈達、輝發、烏喇等扈倫四部與努爾哈齊的和戰關係，對滿洲政權的建立影響大，其中葉赫部納喇氏族人的動向，更具有關鍵地位。葉赫納喇氏宗支繁盛，其家族成員在與努爾哈齊對抗的過程中，既有聯姻關係，也有主動歸順或戰敗投降者，最終都加入滿洲政權，並以蒙古族裔的背景，為皇太極處理蒙古事務。其中，以五世祖尼雅尼雅喀的子孫，在政權中最早取得親貴的地位，和滿洲入關前後的政局發展關係頗深；同時，也只有蘇納、蘇克薩哈父子能夠連續兩代在政治上都有表現，而成為葉赫納喇氏在清初政治上的特例。因此，本文選定清初政體變動最劇烈的兩個階段，即從汗權轉化為皇權、從攝政轉變為輔政的過程中，以蘇納、蘇克薩哈父子為中心，再輔以家族其他成員在政局中的沉浮，用以探討葉赫納喇氏在清初政治史上的地位。至於討論的重點，則集中在：一、葉赫部與努爾哈齊的和戰關係；二、尼雅尼雅喀家族的歸附與婚宦；三、蘇納及其家族和皇太極的互動；四、順康年間蘇克薩哈的政治選擇。
