Oppida are associated with the Celtic late La Tène culture, emerging during the 2nd and 1st centuries BC, spread across Europe, stretching from Britain and Iberia in the west to the edge of the Hungarian plain in the east.  They continued in use until the Romans began conquering Europe.  North of the River Danube, where the population remained independent from Rome, oppida continued to be used into the 1st century AD. Waldschule für kränkliche Kinder (translated: forest school for sickly children) was the first open air school, built in Westend of Charlottenburg, Germany in 1904 by Walter Spickendorff, a city architect.

It led to the beginning of the open air school movement which quickly spread across Europe and North America.  Approval for the school was granted by the local authority in June 1904 and it opened on August 1.  Spickendorff designed the school to provide the most exposure to the sun.  The school took its name from its situation within a pine tree forest, the Grunewald, part of Germany's capital since 1920.

The Women's Peace Crusade was a grass-roots socialist movement that spread across Great Britain between 1916 and 1918.  Its central aim was to spread a 'people's peace', which was defined as a negotiated end to the First World War without any annexations or indemnities.  The movement was first established in Glasgow in July 1916, and officially launched on 10 June 1917.  It later spread across Great Britain, with demonstrations taking place in Leeds, Bradford, Leicester, Birmingham and Lancashire.  Although it gathered a substantial following, the Women's Peace Crusade faced opposition from both the government and police, with members being arrested and reportedly threatened. The English landscape garden, also called English landscape park or simply the English garden (French: "Jardin à l'anglaise" , Italian: "Giardino all'inglese" , German: "Englischer Landschaftsgarten" , Portuguese: "Jardim inglês" , Spanish: "Jardín inglés" ), is a style of "landscape" garden which emerged in England in the early 18th century, and spread across Europe, replacing the more formal, symmetrical "jardin à la française" of the 17th century as the principal gardening style of Europe.  The English garden presented an idealized view of nature.  It drew inspiration from paintings of landscapes by Claude Lorrain and Nicolas Poussin, and, in the Anglo-Chinese garden, from the classic Chinese gardens of the East, which had recently been described by European travellers.  The English garden usually included a lake, sweeps of gently rolling lawns set against groves of trees, and recreations of classical temples, Gothic ruins, bridges, and other picturesque architecture, designed to recreate an idyllic pastoral landscape.  The work of Lancelot "Capability" Brown was particularly influential.  By the end of the 18th century the English garden was being imitated by the French landscape garden, and as far away as St. Petersburg, Russia, in Pavlovsk, the gardens of the future Emperor Paul.  It also had a major influence on the form of the public parks and gardens which appeared around the world in the 19th century. Dada was an artistic and cultural movement between the years 1915 and 1923.

The very word Dada is notoriously difficult to define and its origins are disputed, particularly amongst the Dadaists themselves.
