The Faiyum Oasis and Senuseret II.
A new king is on the throne in 1892 BCE - Kha-kheper-Re Senusret II, son of Amenemhat II.
Moving his pyramid south, to Lahun, the king initiates a series of building projects in the region of the Faiyum Oasis.
With innovations in tomb security, irrigation projects and a new workers' community all underway at once, it is a period of bustle and hustle in the region of Middle Egypt.
