A Liao Dynasty helmet discovered in 1999, 10-12th century. Jianping County, Liaoyang City, Liaoning Province.

A helmet of uncertain age，found in Jingxiang County，Shandong Province.I personally think it might have been made in the Ming Dynasty.

This helmet is covered in beautifully detailed silver inlay of scrolling foliage, Chinese-style lions and Tibetan Buddhist lamas. This type of decoration dates from the 9th to the 14th century and demonstrates the influence of Tibetan Buddhism throughout China and Central Asia during the Mongol Yuan Dynasty (1271-1368). Originally, it would have had a neck guard and peak attached as well. The overall quality of the helmet suggests that it probably belonged to a wealthy Yuan officer.
This rounded type of helmet was popular across a wide region of Central Asia and China. The arms and armour of this vast geographical area share many similarities as a result of warfare, migration and trade. When this helmet was produced, the expansion of the Mongol Empire was a vital factor. This began under Genghis Khan in the 13th century and by the 14th century the Mongol rulers controlled the largest contiguous land-based empire in history.
This helmet is a truly multi-cultural piece. Cultural exchange and at least partial assimilation with the conquered people of their vast empire was a crucial element of the Mongols' success, as they both adopted and disseminated military developments, spiritual philosophies and cultural practices. Further evidence of this far-flung influence can be seen in this 15th century Turkish helmet.
