7:38 p.m., rue Ligner, Paris 20th.

Dancing in front of a portrait of María Eugenia Ignacia Agustina de Palafox y Kirkpatrick, 19th Countess of Teba, known as Eugénie de Montijo (Franz Xavier Winterhalter (1853).

After my dance, I read on the internet that the regency she regency she exercised in 1870-71 made her the last woman to have governed France with the prerogatives of a head of state.
