The composition of and the relationship between the Second Intermediate Period dynasties are still unclear. The present study proposes that Egypt is united during the first half of Dynasty 13 but divided following Merneferra Ay. The Middle Kingdom wꜥrwt system is applied to this division: late Dynasty 13 rules the District of the South (centered at Itjtawy), Dynasty 15 rules the District of the North (centered at Avaris), and Dynasty 16 the District of the Head of the South (centered at Thebes). Dynasty 14 consists of a conglomeration of kinglets in the Delta contemporary with Dynasty 15. Dynasty 17 evolves from the Thinite subdistrict and takes over half of the territory of Dynasty 16, at the end of the reign of Nebiryrau I. The number of kings for each dynasty can be reconstructed on the basis of a combination of the data in Manetho and in the Turin King List.

第二中间时期各朝代的构成和相互关系尚不清楚。本研究提出埃及在第 13 王朝的前半期统一，但在 Merneferra Ay 之后分裂。中央王国wꜥrwt系统适用于这个划分：晚期13统治南方地区（以Itjtawy为中心），第15王朝统治北方地区（以阿瓦利斯为中心），第16王朝统治首领地区南部（以底比斯为中心）。第 14 王朝由与第 15 王朝同时代的三角洲的一群小王组成。 第 17 王朝从 Thinite 分区演变而来，并在 Nebiryrau I统治结束时占据了第 16 王朝的一半领土. 结合马内托和都灵王表中的数据，可以重建每个朝代的国王数量。
