An Anti-Mongol History Thread

Welcome to this week’s History Thread!

Today’s topic: important historical events that aren’t well known. This topic is inspired by today’s anniversary, the Battle of Đông Bộ Đầu in 1258, where a Vietnamese army led by Trần Thái Tông defeated the first Mongol invasion of Dai Viet, the first of several Mongol attempts to subjugate Indochina.
