context_page_description: The 3rd century AD was the period from 201 to 300
  In this century, the Roman Empire saw a crisis, starting with the assassination of the Roman Emperor Severus Alexander in 235, plunging the empire into a period of economic troubles, barbarian incursions, political upheavals, civil wars, and the split of the Roman Empire through the Gallic Empire in the west and the Palmyrene Empire in the east, which all together threatened to destroy the Roman Empire in its entirety, but the reconquests of the seceded territories by Emperor Aurelian and the stabilization period under Emperor Diocletian due to the administrative strengthening of the empire caused an end to the crisis by 284. This crisis would also mark the beginning of Late Antiquity.
  In Persia, the Parthian Empire was succeeded by the Sassanid Empire in 224 after Ardashir I defeated and killed Artabanus V during the Battle of Hormozdgan. The Sassanids then went on to subjugate many of the western portions of the declining Kushan Empire.

  In China, the chaos that had been raging since 189 would ultimately continue to persist with the decisive defeat of Cao Cao at the Battle of Red Cliffs in 208, which would increasingly end the hopes of unification and lead to the tripartite division of China into three main empires; Shu, Wu, and Wei, colloquially known as the Three Kingdoms period, which started in 220 with the formal abdication of Emperor Xian of Han to Cao Cao's son, Cao Pi, thereby founding Wei, which would go on to conquer Shu in 263, but would ultimately be united again under the Jin dynasty, headed by the Sima clan, who would usurp Wei in 266, and conquer Wu in 280.
  In India, the Gupta Empire was on the rise towards the end of the century.
  Korea  was ruled by the Three Kingdoms of Korea. Japan entered the Kofun period. The Xiongnu formed the Tiefu state under Liu Qubei. The Southeast Asian mainland was mostly dominated by Funan; the first kingdom of the Khmer people (Cambodians).
  At about this time in Sub-Saharan Africa, the Bantu expansion reached Southern Africa.
  In Pre-Columbian America, the Adena culture of the Ohio River valley declined in favor of the Hopewell culture.  The Maya civilization entered its Classic Era.
