During the Early Dynastic period southern and northern Babylonia followed different courses of political and economic development. In the Sumerian-speaking South, people lived in small, temple dominated theocratic city-states which were (according to the official ideology) the private property of a divine family. The highest southern official (Sumerian "ensik") functioned as the earthly representative of a city-god rather than an independent secular ruler. In the North, which was settled mainly by Semitic peoples, probably the ancestors of the Akkadians, P . Steinkeller believes that a strong, territorial state emerged, centered around the city of Kish. This state, or political configuration, which also included the Diyala region and the Euphrates valley as far as Mari, was ruled by a secular and authoritarian king(s). The first "palaces" known from the archaeological record monumental buildings which were the seat of a ruler largely independent from the temple - sprung up in northern Babylonia and to the north and west of it. In the author's opinion, a large edifice uncovered at Eridu is part of a religious complex rather than a palace. The function of the socalled "Palac e A" at Kish cannot be determined beyond doubt, but it is highly probable that it was in fact the seat of a king. Pre-Sargonid palaces from Mari, Tell Beidar and Ebla can be linked with Semitic city-states. Another palace like building was discovered in Tell Chuera in northern Mesopotamia. No remains of Early Dynastic period palace buildings are known from southern Babylonia. While this may be due to insufficient archaeological work completed in the Sumer region, it is also worth considering that the idea of strong and secular rule, originally alien to the Sumerian civilization, was adopted under the influence of Semitic neighbours from the North....
Mury obronne Chersonezu są badane od lat 80.
XIX w. Większość zachowanych reliktów została odsłonięta
w czasach, gdy do interpretacji styku warstw archeologicznych
i architektury nie przykładano wystarczającej uwagi.
Również dokumentacja i publikacje z badań pozostawiają
wiele znaków zapytania. W tej sytuacji każdy archeolog
i architekt ma dużą swobodę wyciągania wniosków, trudno
dziś jednak zauważyć znaczący postęp w dyskusji na temat
umocnień Chersonezu....
Grand Duchy of Lithuania lost strategical points in frontier zone (Smolensk, Polotsk), as a result of wars against Russia, which were waged in XVI century. These yields showed the direction of Moscow’s expansion, toward Baltic Sea. Stefan Batory’s campaigns let the Commonwealth to regain Polotsk Province and Livonia. In the period of so-called Dymitriady Polish-Lithuanian state exploited the Moscow’s difficult position, taking Smolensk (1611) and, thanks to Deulino truce, lands of Smolensk, Chernigov and Seversk. Moscow was unable to regain its lost territories in the time of war, waged in 1632–34 and only after thirteen years war (1654–67) took contested lands. Besides them, Russia won Left Bank Ukraine with Kiev (Andrusovo Treaty, January 1667), what was confirmed in peace treaty in 1686. The Commonwealth lost the rivalry with Russia in that part of Europe, since it was not able to conduct more active policy in the East, because of the King John III Sobieski’s engagement in conflict with Ottoman Turkey together with the Holy League....
