Why is "Ragged school" trending?

Wikipedia Overview

Ragged schools were charitable organisations dedicated to the free education of destitute children in 19th-century Britain. The schools were developed in working-class districts and intended for society's most impoverished youngsters who, it was argued, were often excluded from Sunday School education because of their unkempt appearance and often challenging behaviour. After a few such schools were set up in the early 19th century by individual reformers, the London Ragged School Union was established in April 1844 to combine resources in the city, providing free education, food, clothing, lodging, and other home missionary services for poor children. Although the Union did not extend beyond London, its publications and pamphlets helped spread ragged school ideals across the country before they were phased out by the final decades of the 19th century.
