The Prussian education system refers to the system of education established in Prussia as a result of educational reforms in the late 18th and early 19th century, which has had widespread influence since.
 It is predominantly used as an American political slogan in educational reform debates, since it was adopted by all American K–12 public schools and major universities as early as the late 18th century, and is often used as a derogatory term for education in the service of nation-building, teaching children and young adults blind obedience to authority, and reinforcing class and race prejudice.
 The actual Prussian education system was introduced as a basic concept in the late 18th century and was significantly enhanced after Prussia's defeat in the early stages of the Napoleonic Wars.
 The Prussian educational reforms inspired other countries and remains important as a biopower in the Foucaultian sense for nation-building.
 Compulsory education on the Prussian example was soon mirrored in Scandinavia, and United States started to adopt the Prussian example.
 Early American adopters include Daniel Coit Gilman, who set up The General Education Board, later renamed The Rockefeller Foundation, and first president of Johns Hopkins, John Dewey at the University of Chicago, James McKeen Cattell at The University of Pennsylvania and Columbia University, Henry Philip Tappan at The University of Michigan, James Earl Russell at the New York College for the Training of Teachers, and many more.
 France and the UK failed to introduce similar systems until the 1880s.
Ionia is a frame house near Trevilians, Virginia, that was the centerpiece of a large plantation in the late 18th and early 19th centuries.
 Built around 1775, Ionia was the home of the Watson family.
 It was built as Clover Plains by Major James Watson, the son of a Scottish immigrant, in a fertile area of Louisa County, Virginia that is now a National Historic Landmark District, the Green Springs National Historic Landmark District.
 The plantation was the third largest in Louisa County in the late 18th century, leading to the nickname "Wheat Stacks" for Watson as a result of his prosperity.
 After Major Watson's death in 1845 the house passed to his son, Dr. George Watson, who renamed the house "Ionia" and, since he lived in Richmond, used it as a summer residence.
 George Watson died in 1854, leaving Ionia to his widow, who lived there until the 1870s.
 Following her death in 1879 the property was subdivided.
 The Watson family went on to build a number of houses in the Green Springs area.
Colonial buildings and structures in Jakarta include those that were constructed during the Dutch colonial period of Indonesia.
 The period (and the subsequent style) succeeded the earlier period when Jakarta (known then as Jayakarta/Jacatra), governed by the Sultanate of Banten, were completely eradicated and replaced with a walled city of Batavia.
 The dominant styles of the colonial period can be divided into three periods: the Dutch Golden Age (17th to late 18th century), the transitional style period (late 18th century – 19th century), and Dutch modernism (20th century).
 Dutch colonial architecture in Jakarta is apparent in buildings such as houses or villas, churches, civic buildings, and offices, mostly concentrated in the administrative city of Central Jakarta and West Jakarta.

Italian Neoclassical and 19th-century art refers to painting and the plastic arts made in Italy or by Italian artists in the Neoclassical period (late 18th – c. mid-19th centuries) and the 19th century.
 In the late 18th and 19th centuries, Italy went through a great deal of political, social, economic and cultural changes and reforms, including several foreign invasions, most notably by Napoleon Bonaparte and the Austrians, several revolutions in 1848 and the turbulent Risorgimento, which resulted in the Italian unification and the Kingdom of Italy.
