Work began on the Institute for Middle Education in 1843, with classes beginning during the 1853–54 academic year. It is now current headquarters of the Basque Parliament and formerly the convent of Santa Clara. The Free University opened in the wake of the revolution of 1868. The university operated from 1869, to just prior to the 1873–1874 term, largely because of the second Carlist War. Chief academics were Ricardo Becerro de Bengoa, Julián Apraiz, Federico Baraibar, and so on. This latter, great Hellenist (1851–1918), was also among the first teachers of Basque in Vitoria-Gasteiz as an off-syllabus subject.
