Here is a question about this article: Florida had become a burden to Spain, which could not afford to send settlers or garrisons. Madrid therefore decided to cede the territory to the United States through the Adams-Onís Treaty, which took effect in 1821. President James Monroe was authorized on March 3, 1821 to take possession of East Florida and West Florida for the United States and provide for initial governance. Andrew Jackson served as military governor of the newly acquired territory, but only for a brief period. On March 30, 1822, the United States merged East Florida and part of West Florida into the Florida Territory.

So... On March 30, 1822, the United States merged East Florida and part of West Florida into the Florida Territory


Here is a question about this article: European higher education took place for hundreds of years in Christian cathedral schools or monastic schools (scholae monasticae), in which monks and nuns taught classes; evidence of these immediate forerunners of the later university at many places dates back to the 6th century. The earliest universities were developed under the aegis of the Latin Church by papal bull as studia generalia and perhaps from cathedral schools. It is possible, however, that the development of cathedral schools into universities was quite rare, with the University of Paris being an exception. Later they were also founded by Kings (University of Naples Federico II, Charles University in Prague, Jagiellonian University in Kraków) or municipal administrations (University of Cologne, University of Erfurt). In the early medieval period, most new universities were founded from pre-existing schools, usually when these schools were deemed to have become primarily sites of higher education. Many historians state that universities and cathedral schools were a continuation of the interest in learning promoted by monasteries.
What is the answer to this question: During which era did universities grow out of already extant schools?

So... early medieval period


Here is a question about this article: In the first decades of the 19th century, Federal architecture and Greek Revival architecture were dominated by Philadelphia architects such as Benjamin Latrobe, William Strickland, John Haviland, John Notman, Thomas U. Walter, and Samuel Sloan. Frank Furness is considered Philadelphia's greatest architect of the second half of the 19th century, but his contemporaries included John McArthur, Jr., Addison Hutton, Wilson Eyre, the Wilson Brothers, and Horace Trumbauer. In 1871, construction began on the Second Empire-style Philadelphia City Hall. The Philadelphia Historical Commission was created in 1955 to preserve the cultural and architectural history of the city. The commission maintains the Philadelphia Register of Historic Places, adding historic buildings, structures, sites, objects and districts as it sees fit.
