How long was the rule of the dynasty that was active when the Rosetta Stone was inscribed?
Rosetta Stone The Rosetta Stone is a granodiorite stele, found in 1799, inscribed with three versions of a decree issued at Memphis, Egypt in 196 BC during the Ptolemaic dynasty on behalf of King Ptolemy V. The top and middle texts are in Ancient Egyptian using hieroglyphic script and Demotic script, respectively, while the bottom is in Ancient Greek. As the decree has only minor differences between the three versions, the Rosetta Stone proved to be the key to deciphering Egyptian hieroglyphs.
Senusret II Khakheperre Senusret II was the fourth pharaoh of the Twelfth Dynasty of Egypt. He ruled from 1897 BC to 1878 BC. His pyramid was constructed at El-Lahun. Senusret II took a great deal of interest in the Faiyum oasis region and began work on an extensive irrigation system from Bahr Yussef through to Lake Moeris through the construction of a dike at El-Lahun and the addition of a network of drainage canals. The purpose of his project was to increase the amount of cultivable land in that area. The importance of this project is emphasized by Senusret II's decision to move the royal necropolis from Dahshur to El-Lahun where he built his pyramid. This location would remain the political capital for the 12th and 13th Dynasties of Egypt. The king also established the first known workers' quarter in the nearby town of Senusrethotep (Kahun).
