Burgwallinsel, a former Ukrian burgh on an isle in Lake Oberuckersee

The Ukrani or Ukrians[1] (German: Ukranen, Ukrer, Vukraner, Polish: Wkrzanie) were a West Slavic Polabian tribe in the Uckermark (terra U(c)kera, Uckerland) from the 6th–12th centuries.[2] Their settlement area was centered on the lakes Oberuckersee and Unteruckersee at the spring of the Uecker River. In this region, burghs with a proto-town suburbium were set up at Drense and on an isle in Lake Oberuckersee (near modern Prenzlau).

In 954, Margrave Gero of the Saxon Eastern March (the marca Geronis), aided by Holy Roman Emperor Otto I's son-in-law, Conrad of Lorraine, launched a successful campaign to subdue the Ukrians, who had come within reach of the Holy Roman Empire's Northern March after the 929 Battle of Lenzen. After the 983 revolt of the Obodrites and Lutici, the area became independent again, yet remained under permanent military pressure, especially from Poland and the Holy Roman Empire.

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
