Mandatory schooling is much much older in Germany, see https://de.wikipedia.org/wiki/Schulpflicht_(Deutschland) (in German). It was part of the Weimarer Verfassung of 1919: http://www.verfassungen.de/de/de19-33/verf19.htm (Art.145). In some parts, mandatory schooling laws were first passed in 1592; Prussia in 1717/1763, Bavaria 1802, Saxony 1835, etc. There's really no need to bring up Hitler in every article that mentions Germany.
