On 17 March 1808, Napoleon created by decree a "pensionnat normal" within the imperial University of France charged with "training in the art of teaching the sciences and the humanities". The establishment was opened in 1810, its strict code including a mandatory uniform. By then a sister establishment had been created by Napoleon in Pisa under the name of Scuola normale superiore, which continues to exist today and still has close ties to the Paris school. Up to 1818, the students are handpicked by the academy inspectors based on their results in the secondary school. However, the "pensionnat" created by Napoleon came to be perceived under the Restoration as a nexus of liberal thought and was suppressed by then-minister of public instruction Denis-Luc Frayssinous in 1824.
