The Sixth Dynasty of Egypt lasted from around 2325 to 2150 BCE and is part of the Old Kingdom period. This dynasty is known for its strong central government and the continuation of pyramid building, with notable pharaohs like Pepi I and Pepi II. The era saw advancements in art, architecture, and trade, contributing to Egypt's wealth and stability. During this time, the power of the pharaohs began to decline, leading to increased local authority among nobles. The dynasty ended with a period of instability, which eventually led to the First Intermediate Period. The Sixth Dynasty remains significant for its contributions to Egyptian culture and governance.
