Why is "History of the Spanish language" trending?

Wikipedia Overview

The language known today as Spanish is derived from spoken Latin, which was brought to the Iberian Peninsula by the Romans after their occupation of the peninsula that started in the late 3rd century BC. Today it is the world's 4th most widely spoken language, after English, Mandarin Chinese and Hindi. Influenced by the peninsular hegemony of Al-Andalus in the early middle ages, Hispano-Romance varieties borrowed substantial lexicon from Arabic. Upon the southward territorial expansion of the Kingdom of Castile, Hispano-Romance norms associated to this polity displaced both Arabic and the Mozarabic romance varieties in the conquered territories, even though the resulting speech also assimilated features from the latter in the process. The first standard written norm of Spanish was brought forward in the 13th century by Alfonso X the Wise, probably drawing from the speech of the upper classes of Toledo. Features associated with the Castilian patterns of Hispano-Romance also spread west and east to the kingdoms of León and Aragón for the rest of the middle ages, owing to the political prestige achieved by the Kingdom of Castile in the peninsular context and to the lesser literary development of their vernacular norms. From the 1560s onward the standard written form followed Madrid's.
