Editing Ullern (section)

== History ==
The borough has its name from an old farm, [[Old Norse language|Norse]] ''Ullarin''. The first element is the genitive case of the name of the Norse god [[Ullr]]. The last element is ''vin'', meaning pasture or meadow. In medieval times, the farm belonged to the [[monastery]] at [[Hovedøya]]. Following the [[Protestant Reformation|Reformation]] in 1536, the farmland was separated between the crown and the local [[canon (priest)|canon]]. Formally divided into lower and upper Ullern in 1740, both farms were bought by [[Herman Severin Løvenskiold]], in 1878 and 1866 respectively.<ref name=oby>{{cite encyclopedia|year=2000|title=Ullern|encyclopedia=Oslo byleksikon|edition=4|editor=Tvedt, Knut Are|publisher=Kunnskapsforlaget|location=Oslo|pages=454–455|isbn=82-573-0815-3}}</ref>

At the time, Ullern was a part of the rural municipality [[Aker, Norway|Aker]]. Signs of urbanization began in the 1800s, when Skøyen and areas along the [[Lysakerelva|Lysaker River]], which divides Ullern from [[Bærum]], began developing into industrial sites. The 1872 opening of the [[Drammen Line]] railway was a catalyst for further building activity, as were the 1912 opening of the [[Smestad Line]] and the 1919 extension of the [[Skøyen Line]] to [[Lilleaker]]. The two latter lines were later extended further, in 1935 and 1924 respectively. In 1942, a connection between the two lines, between [[Jar (station)|Jar]] and [[Sørbyhaugen (station)|Sørbyhaugen]], was opened, providing public rail transportation to the northern part of Ullern. In 1948, Ullern became a part of [[Oslo]], when Oslo absorbed the entire Aker municipality. In the post-[[World War II]] period, the [[villa]]-dominated housing was supplemented by [[tower block]]s, scattered across the borough.<ref name=oby/>
