King Dongmyeong of Goguryeo vs Sekhemkhet

Jumong, later known as King Dongmyeong, founded the kingdom of Goguryeo in the region of present-day North Korea and Manchuria. He established the capital at Jolbon and united various tribal groups, creating one of the Three Kingdoms of Korea.

King Dongmyeong built the first Goguryeo fortress at Jolbon, which served as the kingdom's capital and defensive stronghold. The fortress protected the nascent kingdom from external threats and symbolized its sovereignty.

King Dongmyeong led military campaigns against the Malgal (Mohe) tribes in the northern frontier, securing Goguryeo's borders. These victories expanded the kingdom's territory and established its dominance over neighboring nomadic groups.

King Dongmyeong organized Goguryeo's society into five major tribes (Sunobu, Jeollobu, Sunnobu, Gwannobu, and Gaerubu), creating a centralized administrative structure. This system formed the basis for Goguryeo's governance and military organization.

Sekhemkhet began construction of a step pyramid at Saqqara, now known as the Buried Pyramid. The pyramid was planned to be larger than Djoser's step pyramid but was left unfinished, with only the base and lower courses completed. The site includes a surrounding enclosure wall and subsidiary tombs.

The burial chamber of Sekhemkhet's pyramid was found empty, with an alabaster sarcophagus still sealed but containing no remains. This suggests the pharaoh may not have been buried there, or the tomb was robbed in antiquity. The discovery provided insights into early pyramid building techniques.
