use of non-Magyar languages, in strong violation of the 1868 Nationalities Law. In about 61% of these schools the language used was exclusively Magyar, in about 20% it was mixed, and in the remainder some non-Magyar language was used. The ratio of minority-language schools was steadily decreasing: in the period between 1880 and 1913, when the ratio of Hungarian-only schools almost doubled, the ratio of minority language-schools almost halved. Nonetheless, Transylvanian Romanians had more Romanian-language schools under the Austro-Hungarian Empire rule than there were in the Romanian Kingdom itself. Thus, for example, in 1880, in Austro-Hungarian Empire there were 2,756 schools teaching exclusively in the Romanian language, while in the Kingdom of Romania there were only 2,505 (the Romanian Kingdom gained its independence from the Ottoman Empire only two years before, in 1878). The process of Magyarization culminated in 1907 with the lex Apponyi (named after education minister Albert Apponyi) which forced all primary school children to read, write and count in Hungarian for the first four years of their education. From 1909 religion also had to be taught in Hungarian. "In 1902 there were in Hungary 18,729 elementary schools with 32,020 teachers, attended by 2,573,377 pupils, figures which compare favourably with those of 1877, when there were 15,486 schools with 20,717 teachers, attended by 1,559,636 pupils. In about 61% of these schools the language used was exclusively Magyar". Approximately 600 Romanian villages were depleted of proper schooling due to the laws. As of 1917, 2,975 primary schools in Romania were closed as a result. The effect of Magyarization on the education system in Hungary was very significant, as can be seen from the official statistics submitted by the Hungarian government to the Paris Peace Conference (formally, all the Jewish people who spoke Hungarian as first language in the kingdom were automatically considered Hungarians, who had a magnitude higher rate of tertiary education than the Christian populations). By 1910 about 900,000 religious Jews made up approximately 5% of the population of Hungary and about 23% of Budapest's citizenry. They accounted for 20% of all general grammar school students, and 37% of all commercial scientific grammar school students, 31.9% of all engineering students, and 34.1% of all students in human faculties of the universities. Jews were accounted for 48.5% of all physicians, and 49.4% of all lawyers/jurists in Hungary. Source: Paclisanu 1985 Election system The census system of the post-1867 Kingdom
