Grand Principality of Rus' (Ukrainian: Велике Князівство Руське, Polish: Wielkie Księstwo Ruskie, Lithuanian: Didžioji Rusijos Kunigaikštystė),[https://books.google.com/books?id=3ED8CwAAQBAJ Alexander Basilevsky (2016): Early Ukraine: A Military and Social History to the Mid-19th Century (p. 311)] also known in historiography as Grand Principality of Ruthenia, was the project of the state as a member of the Polish–Lithuanian–Ruthenian Commonwealth in the territory of Kiev Voivodeship, Bracław Voivodeship and Chernihiv Voivodeship. Its creation was proposed by Hetman Ivan Vyhovsky with Yuri Nemyrych and Pavlo Teteria in September 1658 during the negotiations between the Cossack Hetmanate and the Commonwealth. The project of the Duchy was approved in the first version of the Treaty of Hadiach, but later, because of the strong resistance of Polish society, the idea of the Grand Principality of Rus was completely abandoned.Т.Г. Таирова-Яковлева Иван Выговский // Единорогъ. Материалы по военной истории Восточной Европы эпохи Средних веков и Раннего Нового времени, вып.1, М., 2009: Under the influence of the Polish society and the strong dictatorship of the Vatican, the Diet in May 1659 adopted the Treaty of Hadiach in more than a truncated form. The idea of the Principality of Ruthenia was even destroyed, as was the provision for maintaining the alliance with Moscow. The abolition of the union was canceled, as was a number of other positive articles. The Cossacks were very disappointed with the final version of the treaty and The Ruin began. Yuri Nemyrych, the alleged author of the Grand Principality of Rus project, was killed in a local fight in August 1659 and Vyhovsky lost his power in October 1659, thus the project did not become a reality.Наталія Яковенко [http://history.franko.lviv.ua/PDF%20Final/Jakovenko.pdf "Нарис історії України з найдавніших часів до кінця ХVІІІ ст."] {{Webarchive|url=https://web.archive.org/web/20201111052824/http://history.franko.lviv.ua/PDF%20Final/Jakovenko.pdf |date=2020-11-11 }}: "На початку серпня 1659 р. в одному зі згаданих локальних боїв на прикордонні від рук людей Цюцюри загинув 47-річний Юрій Немирич, найосвіченіший українець, аристократ і перший канцлер задуманого ним, але так і не збудованого Великого Князівства Руського."{{Cite web |url=http://krotov.info/libr_min/28_ya/ko/vleva_t.htm |title=Т.Г.Яковлева.
