The purpose of this thesis is to analyze and compare the Empress Myeongseong's writing style with the court ladies' who wrote letters for Myeongseong in late Joseon. Based on the analysis, I proposed the necessity for putting her strokes into practical use.Empress Myeongseong (Queen Min, 1851-1895) who lived 45 years of misfortune, was the first Empress, the official wife of King Gojong, the 26th king of Joseon dynasty, and she was the daughter-in-law of Daewongun Haeung Lee (1820-1898). She had a difficult life because of Daewongun's jealousy and regency, Japanese intervention, and political crisis caused by related officials. Under such circumstances, Myeongseong wrote a lot of letters in Hangul (Korean alphabet) to the most faithful people, her parents' family. Among the letters that still exist, I chose four of her long letters she wrote for her cousin, Youngso Min, and four letters written by her court lady, to analyze the writing style. As a result, I found that Myeongseong's strokes in her autograph letters was the same as the court ladies' epistolary style - also called Bongseo - and Myeongseong's style is highly valued for its creativeness and uniqueness. The beauty of epistolary style is categorized into writing pattern, structure and the use of a brush. The style is summarized as follows:I. Myeongseong's sentence pattern is very similar to the court ladies', but more flexible and distinctive.II. Myeongseong's structural expression is similar to the court ladies', but more freely expressed. III. Myeongseong's way of using brush on basic strokes is similar to the court ladies', but Myeongseong followed the eight kinds of brush stroke correctly. Empress Myeongseong's writing style was developed while taking a royal course of the court style of writing, which makes her handwriting look classical, but more natural and unique. Accordingly, Myeongseong's writing style is very highly valued because it was analyzed to be the same or very similar to the court ladies', which had already been proven for beautiful in many other studies. Therefore, Empress Myeongseong's epistolary writing style can be used as a fundamental rule and be applied to Korean calligraphy. Her writing style will offer a great value as a sample for calligraphers.
