Antony CarpenI'm in the process of collecting and digitising old books on civics and political education in schools in England that pre-date me being a 1990s teenager - only my generation were taught zilch about politics. https://archive.org/details/830101-local-and-central-government-1983 This from 1983.
More at https://archive.org/details/@antony_carpen - this one from 1925 ("The model citizen") is particularly excruciating, talking up Empire and talking down in derogatory terms everywhere else!
