Senusret II (Sesostris II) becomes pharaoh of Egypt’s 12th Dynasty; modern chronologies differ, but a commonly cited range places his reign around 1897–1878 BCE, the period associated with the Lahun pyramid project and Faiyum development initiatives.
Senusret II is credited with initiating development of the Al-Faiyum depression, including water-control works intended to regulate lake levels and expand cultivable land—efforts later extended significantly under Amenemhat III.
Accounts of the Faiyum program describe an irrigation system using a dyke and canals to manage water flow associated with Lake Moeris (in the Faiyum), supporting reclamation and farming on newly managed land.
Senusret II establishes his pyramid complex at El-Lahun at the mouth of the Faiyum, anchoring royal presence in the region and tying state resources to both funerary cult administration and landscape development.
The Pyramid of Senusret II is constructed primarily of mudbrick around a limestone structural system, originally cased with fine limestone—an approach characteristic of Middle Kingdom royal building in the region.
A purpose-built, orthogonally planned town—known as Kahun/Lahun—is established near the pyramid complex, generally understood to house administrators, craft workers, and personnel connected to construction and the ongoing royal mortuary cult.
Evidence from the settlement is commonly interpreted as linking Kahun’s primary role to the operation of Senusret II’s pyramid complex—supporting both the building project and later temple and cult functions through resident officials and workers.
The Faiyum initiatives begun under Senusret II become an enduring state priority in the later 12th Dynasty; sources emphasize major continuation and expansion under Amenemhat III.
Papyri associated with Lahun/Kahun preserve administrative and daily-life documentation (e.g., accounts tied to the cult of Senusret II and later Middle Kingdom activity), making the site a key textual window onto state organization and workforces.
The Kahun Gynecological Papyrus—an early medical text focused on women’s health—is dated to the Middle Kingdom (commonly c. 1825 BCE) and is among the best-known papyri recovered from Lahun.
W. M. Flinders Petrie undertakes major excavations at Lahun/Kahun (including the town plan, houses, and finds), establishing the site as one of the most important archaeological case studies for a planned Middle Kingdom town.
Petrie publishes a key early synthesis of his work, helping disseminate the settlement evidence (architecture, objects, and papyri) that made Kahun central to reconstructions of Middle Kingdom work, administration, and domestic life.
