Overview
Discovery
In March 1974, local farmers drilling a well near the earthen mound of Qin Shi Huang's mausoleum unearthed fragments of terracotta pottery, leading to the discovery of one of the most staggering archaeological finds of the 20th century. Archaeologist Zhao Kangmin soon identified the fragments as part of an army buried to protect the first emperor of a unified China. Subsequent excavation revealed three vast underground pits containing thousands of life-sized soldiers, horses, and chariots.
Purpose and Context
The mausoleum complex was conceived by Qin Shi Huang (259–210 BCE), who unified China in 221 BCE and ordered construction of his tomb soon after becoming king of Qin at age 13. Historical texts, notably Sima Qian’s Records of the Grand Historian (c. 94 BCE), describe a magnificent subterranean palace, but conspicuously omit mention of the terracotta army. The army was likely intended to project imperial power into the afterlife and to symbolically protect the emperor from the threats he faced in his conquests.

"In the ninth month the First Emperor was buried at Mount Li. Craftsmen were ordered to install mechanical crossbows so that any thief breaking in would be shot. Whole models of palaces, towers, and offices, and rare implements were brought into the tomb."
— Sima Qian, Records of the Grand Historian (Shiji), c. 94 BCE
Production and Craftsmanship
Each figure is unique in facial features, though analysis suggests an early form of mass production: heads, torsos, and limbs were molded separately and assembled, with final detailing added by hand. The figures originally bore vivid polychrome paint—pink faces, black hair, and colorful armor—but most of the lacquer-based pigment decayed within minutes of exposure to air after excavation. The bronze weapons interred with the warriors, including swords and crossbow triggers, were actual functional arms, many still sharp and coated with a chromium-rich layer that prevented rust.

Layout and Composition
Three pits (a fourth is empty) hold an estimated 8,000+ figures arranged in precise military formation. Pit 1, the largest, contains over 6,000 infantry and charioteers in battle array. Pit 2 houses a mixed force of cavalry, archers, and chariots, while Pit 3 is interpreted as a command headquarters with high-ranking officers. The layout mirrors Qin military tactics and reveals sophisticated planning of the afterlife garrison.
Conservation Challenges
The site presents immense conservation challenges. The rapid deterioration of pigments has forced selective excavation; most of the central tomb mound remains unopened due to preservation concerns and legendary traps. Remote sensing and soil analysis have confirmed elevated mercury levels, consistent with ancient accounts of rivers of mercury. The site became a UNESCO World Heritage Site in 1987, and ongoing efforts combine meticulous excavation, micro-climate control, and chemical stabilization to safeguard this fragile legacy.
