Đàng Trong

Throughout the 17th century and most of the 18th century, the Nguyễn lords, though claiming loyalty to the Lê emperors in Thăng Long (Hanoi), ruled Đàng Trong as a de facto independent kingdom. Nguyễn rulers titled themselves as Chúa (chữ Nôm: 主, lit. "Lord") instead of Vua (chữ Nôm: 𤤰, lit. "King") until Lord Nguyễn Phúc Khoát officially claimed the title Vũ Vương (chữ Nôm: 武王, lit. "Martial King") in 1744.

Names

The terms Đàng Trong and Đàng Ngoài originated in the 1620s and were first recorded in the Dictionarium Annamiticum Lusitanum et Latinum by Alexandre de Rhodes. Contemporary European sources referred to Đàng Trong as Cochinchina and its variants. Other foreigners also referred to it as the Kingdom of Quảng Nam (chữ Hán: 廣南國, Quảng Nam quốc) after the Quảng Nam Governorate where the important harbor Hội An (Faifo) located, hence the Dutch term Quinam.
