Ле Лой
A few historians believe that the Thuận Thiên sword was an expedient of Lê Lợi's strategist Nguyễn Trãi, regarding it as a ploy to gain legitimacy for Lê Lợi to lead an uprising against the Chinese. The expedient was successful, as the sword's legend quickly spread across the country, leading the populace to regard Lê Lợi as the rightful ruler of Vietnam, especially among those with high levels of antipathy towards the Chinese, who were longstanding historical enemies of Vietnam.
