ÃÂào Duy Từ (1572 - December 7, 1634) was a Vietnamese scholar, poet, military adviser, and mandarin who served under the reign of Nguyá» n lord Nguyá» n Phúc Nguyên.
ÃÂào Duy Từ, born in Hoa Trai village, Ngá»Âc Sán, Lðáng Sán, HoàBình (present day Ngá»Âc Sán, Lðáng Sán, Lðáng Sán District, HoàBình Province), was a son of ÃÂào Tả Hán, a Vietnamese folk singer, who died when Từ was five years old. After this Từ was raised solely by his mother, a woman named Và © Thá» Kim Chi. When Từ was 14 years old his mother sent him to study Confucianism under a local scholar named Nguyá» n ÃÂức Khoa. ÃÂào Duy Từ was however forbidden from taking the court examination because his father's profession as a folk singer was considered the most shameful profession under the Confucian system of the Lê dynasty.
Từ's mother managed to bribe a low-ranking mandarin named Lðu Minh Phðáng to change Tu's surname from ÃÂào to Và © which gave Từ a chance to take the court examination. In 1593, ÃÂào Duy Từ, under the false name Và © Duy Từ, passed his first court examination which prompted Lðu Minh Phðáng to demand that Từ's mother marry him as a payment for his help. Phðáng's demand was rejected and therefore he angrily reported the case of ÃÂào Duy Từ to a local mandarin. Because of this Từ was expelled from the examination school while he was taking the second court examination in ThÃÂng Long. After learning of this failure his mother blamed herself and committed suicide by cutting her throat. Both his mother's death and his failure in the examination lead to Từ becoming seriously ill. After some years of inactivity, ÃÂào Duy Từ went south to the land of Nguyá» n Lords.
After arriving in southern Vietnam, ÃÂào Duy Từ attempted to meet Lord Nguyá» n Phúc Nguyên but failed. After that, Từ became a worker for a landlord named Chúc Trá»Ânh Long in Tùng Châu (present day Bá»Âng Sán, Bình ÃÂá»Ânh Province) in order to get close to Trần ÃÂức Hòa, a neighbor of Chúc Trá»Ânh Long and a mandarin of Lord Nguyá» n Phúc Nguyên. This attempt was a success: after learning of Từ's ability, Trần ÃÂức Hòa gave his daughter's hand to ÃÂào Duy Từ and hired him as the family tutor . At this time, Từ composed a famous Vietnamese language poem, "Ngá»Âa Long Cðáng Vãng" (Singing of a Lying Dragon), in which he compared himself to famous Chinese military strategist Zhuge Liang.
On an occasion when Trần ÃÂức Hòa met Lord Nguyá» n Phúc Nguyên, Hòa give the Lord the poem "Ngá»Âa Long Cðáng Vãng" of ÃÂào Duy Từ. After reading the poem, Lord Nguyá» n Phúc Nguyên ordered Trần ÃÂức Hào bring ÃÂào Duy Từ to meet him.
Wanting to test ÃÂào Duy Từ, the Nguyá» n lord wore casual clothing and stood near a small door of Phú Xuân Palace when ÃÂào Duy Từ first met him (these actions could be considered as a disdain by confucianist scholars during this time). Thereon ÃÂào Duy Từ kept refusing to talk with Lord Nguyá» n Phúc Nguyên until the lord opened the main gate of the palace and wore formal clothing. After a long meeting in which ÃÂào Duy Từ discussed and gave advice about the current Trá»ÂnhâÂÂNguyá» n War, Lord Nguyá» n Phúc Nguyên appeared to like ÃÂào Duy Từ's ability and then he made ÃÂào Duy Từ his advisor and a high ranking mandarin.
From this point on, ÃÂào Duy Từ served as the chief military advisor, directing the construction of Nguyen's two famous strategic lines of defense: the ramparts of Là ©y Thầy and Là ©y Trðá»Âng Dục, in northern ThuáºÂn Hóa (present day Quảng Bình Province). During the Trá»ÂnhâÂÂNguyá» n War, Là ©y Thầy and Là ©y Trðá»Âng Dục were largely impregnable, enabling the Nguyá» n lords to defend themselves against the Trá»Ânh invasions, despite the population and army of the Nguyá» n being smaller than those of the Trá»Ânh lords.
In 1627, when these ramparts were completed, ÃÂào Duy Từ presented a double-bottomed tray to the Lê Emperor in which he concealed the royal decree that demanded the Nguyá» n lord to submit to the Lê emperors. He then carved the tray with a cryptic poem that involves a letter play, upon solving would reveal the message: äºÂä¸ÂÃ¥ÂÂÃ¥ÂÂ, meaning Lord Nguyá» n Phúc Nguyên does not accept the decree. He topped the tray with gifts and sent an envoy bringing it to ThÃÂng Long. Unaware of the hidden content, Lord Trá»Ânh Tráng accepted the tray and Tu's letter remained undiscovered until the Nguyá» n envoy had fled back to the south. After learning the true meaning of ÃÂào Duy Từ's poem; Lord Trá»Ânh Tráng got angry and sent a large army to the south, starting the Trá»ÂnhâÂÂNguyá» n War.
No information regarding the family of ÃÂào Duy Từ was recorded except that ÃÂào Duy Từ had a daughter who married Nguyá» n Hữu Tiến, one of the two most important commanders of the Nguyá» n army in the Trá»ÂnhâÂÂNguyá» n War.
In 1633, after nine years service to the Nguyá» n lords, ÃÂào Duy Từ died of an illness. Lord Nguyá» n Phúc Nguyên posthumously gave him the title of "Hiá»Âp ÃÂá»Âng mðu ÃÂức công thần, ÃÂặc tiến Kim tá» Vinh lá»Âc ÃÂại phu" (Common Strategist Merit-man, especially entitled as "Glorious, Fortunious and Golden Grand Scholar"). Later emperor Gia Long had ÃÂào Duy Từ worshiped along with the Nguyá» n Lords in Thế Miếu temple, the main temple of the Nguyá» n emperors' ancestors in Huế. During the reign of Emperor Minh Mạng ÃÂào Duy Từ was posthumously bestowed with the title of Hoằng Quá»Âc Công (Duke Hằng Quá»Âc).
Most cities in Vietnam, regardless of the political orientation of the government, have named major streets after him. Despite the ruling communist party's disapproval of the Nguyá» n lords and the subsequent Nguyá» n dynasty as "feudal" and "reactionary", and their renaming of streets and public facilities named after most Nguyen leaders, streets named after ÃÂào Duy Từ remain.
