Ancient China 
The area of Huai'an spans over ancient canal of Huai River and the name of Huai'an takes the hope of the residents for lasting peaceful Huai River.
Traces of the activities of ancient Chinese living in about 5000 to 6000 years ago have been found in the area. The most famous one is the Qingliangang Hill Civilization.
Xia, Shang and Zhou Dynasty
The borough area had been properly developed, and was leading China in convenience of transportation and irrigation. Gangou Drain (the section between Huaiyin and Yangzhou of the Grand Canal of China) connected the Yangtze River and the Huai He delta region. The Qian Road and Shan Road that traversed the region reached Southern and Northern China. Thus, Huaiyin was critical area for several strong states in Spring and Autumn period. The region was occupied by the Wu, Yue and Chu states, one after another.
Qin and Han Dynasty
After Qin Dynasty consolidated all states in China, County System was promoted throughout China. Huaiyin County (Matou Town of Huaiyin District today), Xuyi Country (Northern town of Xuyi County today), Dongyang (Maba of Xuyi County today) was built in the region today.
In a movement of rebelling farmers during the later years of Qin Dynasty, the people of Huai'an supported the rebel forces, including the famous militia Han Xin who was highly honored for his bravery and meritorious deeds.
In the epoch of West Han Dynasty, Huaipu County (Western Lianshui County today), Sheyang County (Southeast of Huai'an District today) and Fulin County (under the water of Hongze Lake today) were built.
During the Qin and Han Dynasty, great improvements, especially in irrigation, were made to agriculture and manufacturing. In the later years of East Han Dynasty, the Governor of Guanglin, Cheng Deng, built the Gaojiayang Levees (Hongze Lake Levees today). 30 miles in total, which kept out flood waters, and protected farmlands. He also built Pofu Pool for farm irrigation. Iron-made apparatus and bull-farming were widespread. Though a few wars and battles took place, agriculture, transportation and logistics made fair progress. The express way built by the first Qin Emperor went through the region, and the West Way of Gaogou Drain built by Cheng Deng, improved traffic between Yangtze and Huai He area.
Handicrafts and business also developed during this period, while culture and the arts were at high levels, as well. Home-teaching and private schools flourished in Han Dynasty and many famous artists appeared, for example, the Han-text composers Mei Chen and Mei Gao, and Chen Lin, one of the Seven Scholars of Jian'an.
Wei, Jin, and Southern and Northern Dynasties
Sui, Tang and Five Dynasties
Song and Yuan Dynasty
Ming and Qing Dynasty
The Ming Dynasty Ancestor Tomb (Ming Zu Ling) [明祖陵] is located in Xu Yi County (Xu Yi Xian) [盱眙县], the former Sizhou, of the Huai An Municipality (Huai An Shi) [淮安市]. This location was chosen for the tomb because the founder of the Ming Dynasty, Zhu Yuan Zhang (1328-1398), aka Hong Wu (1368-1398), was conceived in Xuyi town of Huai'an, and his grandfather died there, while his family was moving from Sizhou to Fengyang in Anhui. Three of the Hong Wu emperor's ancestors were buried here, his grand father, his great gradfather, and his great great grandfather. Today the tomb site features a sacred way (shen dao) with one of the most impressive collections of Ming Dynasty stone statues in all of China.
