Ang kapanahunan ng '''Tatlong Kaharian''' <!--------(traditional Chinese: 三國; simplified Chinese: 三国; pinyin: Sānguó) is a period in the history of China,---------> ay isang bahagi ng panahon ng kawalan ng pagkakaisang tinatawag na Anim na Dinastiyang dagliang sumunod sa pagkaalis ng tunay na kapangyarihan ng mga emperador ng [[Dinastiyang Han]].
part of an era of disunity called the Six Dynasties following immediately the loss of de facto power of the Han Dynasty emperors. In a strict academic sense it refers to the period between the foundation of the Wei in 220 and the conquest of the Wu by the Jin Dynasty in 280. However, many Chinese historians and laymen extend the starting point of this period back to the uprising of the Yellow Turbans in 184.
Although relatively short, this historical period has been greatly romanticised in the cultures of China, Japan, Korea, and Vietnam. It has been celebrated and popularised in operas, folk stories, novels and in more recent times, films, television serials, and video games. The best known of these is undoubtedly the Romance of the Three Kingdoms, a fictional account of the period which draws heavily on history. The authoritative historical record of the era is Chen Shou's Sanguo Zhi, along with Pei Songzhi's later annotations of the text.
Technology advances significantly during this period. Zhuge Liang invented the wooden ox, suggested to be an early form of the wheelbarrow. A brilliant mechanical engineer known as Ma Jun, in the Kingdom of Wei, is considered by many to be as brilliant as his predecessor Zhang Heng. He invented a hydraulic-powered, mechanical puppet theatre designed for Emperor Ming of Wei (Cao Rui), square-pallet chain pumps for irrigation of gardens in Luoyang, and the ingenious design of the South Pointing Chariot, a non-magnetic directional compass operated by differential gears.'''Tekstong matapang'''
