Don Luis José Sartorius y Tapia, 1st Count of San Luis (Seville, Spain, 1820 – Madrid, Spain, 22 February 1871) is a Spanish noble, politician and journalist who serves as Prime Minister of Spain from 1853 to 1854, during the reign of Queen Isabella II.
Sartorius, a man of very traditional convictions, is the leader of a faction of the Moderate Party which, because of his Polish origin, is known as the polacos (English: the polish).
His newspaper, El Herlado, becomes one of the mainstays of the moderates during the regency of the progressivist Baldomero Espartero.
During the Moderate decade (1844-1854), Sartorius holds several political offices, such as Minister of Gobernation, and attains the position of Prime Minister in 1853.
