アストラハン・ハン国
At the start of the 16th century, the Grand Duchy of Moscow managed to annex the Pskov Republic and conquer the Grand Duchy of Ryazan as well as secure number of territories that belonged to the Grand Duchy of Lithuania such as the Upper Oka Principalities and Sloboda Ukraine, thus extending its territory far south. In 1708, the Oka principalities and Sloboda Ukraine were incorporated into the first Kiev Governorate. During the second half of the 16th century, the Grand Duchy of Moscow managed to conquer number of West-Siberian and Volga duchies and khanates such as Kazan Khanate, Siberia Khanate, Astrakhan Khanate, Great Nogai Horde and many others. Some of the territorial acquisitions, however, were lost during the Time of Troubles.
