QUES: When the Central Junta fell to the French, numerous new Juntas appeared all across the Americas, eventually resulting in a chain of newly independent countries stretching from Argentina and Chile in the south, to Mexico in the north. After the death of the king Ferdinand VII, in 1833, only Cuba and Puerto Rico remained under Spanish rule, until the Spanish–American War in 1898. Unlike the Spanish, the Portuguese did not divide their colonial territory in America. The captaincies they created were subdued to a centralized administration in Salvador (later relocated to Rio de Janeiro) which reported directly to the Portuguese Crown until its independence in 1822, becoming the Empire of Brazil.

QUES: In the early 19th century, the role of Utrecht as a fortified town had become obsolete. The fortifications of the Nieuwe Hollandse Waterlinie were moved east of Utrecht. The town walls could now be demolished to allow for expansion. The moats remained intact and formed an important feature of the Zocher plantsoen, an English style landscape park that remains largely intact today. Growth of the city increased when, in 1843, a railway connecting Utrecht to Amsterdam was opened. After that, Utrecht gradually became the main hub of the Dutch railway network. With the industrial revolution finally gathering speed in the Netherlands and the ramparts taken down, Utrecht began to grow far beyond the medieval centre. In 1853, the Dutch government allowed the bishopric of Utrecht to be reinstated by Rome, and Utrecht became the centre of Dutch Catholicism once more. From the 1880s onward neighbourhoods such as Oudwijk, Wittevrouwen, Vogelenbuurt to the East, and Lombok to the West were developed. New middle class residential areas, such as Tuindorp and Oog in Al, were built in the 1920s and 1930s. During this period, several Jugendstil houses and office buildings were built, followed by Rietveld who built the Rietveld Schröder House (1924), and Dudok's construction of the city theater (1941).
