Possible vandalism. The reasons for removing the text are probably chauvinistic. Relevant historical sources and literature are listed. With a few clicks, the correctness of the data can be checked. If there is any objection, write it and we will discuss it and I will also quote other relevant titles if necessary.

The article "Humska zemlja" and "Duchy of St. Sava"should be separated. Hum is a historical area i from 7 -14 centuries and with special state traditions (up to the middle of 14 centuries as part of Raska) while Duchy of Saint Sava /Herzegovina Svetoga Save/Ducatus Sancti Sabe)has been the area and state of Kosača noble family in 15th century. Even in a geographical sense there is a difference between this the two terms.
