위나라, or the Wei Kingdom, was one of the three major states during the Three Kingdoms period in ancient China. It was established in the early 3rd century AD and was known for its strong military and strategic leadership, particularly under the rule of Cao Cao. The kingdom's capital was located in Xuchang. The Wei Kingdom played a significant role in the power struggles of the time, often clashing with its rivals, the Shu Kingdom and the Wu Kingdom. Despite its initial successes, the Wei Kingdom eventually fell to internal strife and external pressures, leading to its dissolution in the late 3rd century.
