Editing Celje (section)

===19th century===
The first [[train|service]] on the [[Vienna]]-[[Trieste]] [[Austrian Southern Railway|railway line]] came through Celje on 27 April 1846. In 1895, [[I. high school in Celje|Celje secondary school]], established in 1808, began to teach in [[Slovene language|Slovene]].

At the end of the 19th century and in the early 20th century, Celje was a center of German [[nationalism]] which had repercussions for [[Slovenes]]. The 1910 census showed that 66.8% of the population was German.<ref>For more information on the 1910 Austro-Hungarian census, see ''Geographischer Atlas zur Vaterlandskunde an der österreichischen Mittelschulen''. K. u. k. Hof-Kartographische Anstalt G. Freytag & Berndt, [[Vienna]] 1911.</ref> A symbol of this was the German Cultural Center ({{langx|de|Deutsches Haus}}), built in 1906 and opened on 15 May 1907, today it is [[Celje Hall]] ({{langx|sl|Celjski dom}}). The centuries-old German name of the town, ''Cilli'', sounded no longer German enough to some German residents, the form ''Celle'' being preferred by many.

Population growth was steady during this period. In 1900, Celje had 6,743 inhabitants and by 1924 this had grown to 7,750. The [[National Hall, Celje|National Hall]] (''Narodni dom''), which hosts the Mayors Office and Town Council today, was built in 1896. The first [[telephone]] line was installed in 1902 and the city received [[electricity|electric power]] in 1913.

Slovene and [[German ethnic nationalism]] increased during the 19th and early 20th centuries. With the collapse of Austria-Hungary in 1918 as a result of World War I, Celje became part of the [[Kingdom of Serbs, Croats and Slovenes]] (later known as [[Yugoslavia]]). During this period, the town experienced a rapid industrialization and a substantial growth in population.
