1975 Spanish Grand Prix
It was the 21st Spanish Grand Prix since the race was first held in 1913. It was the fourth, and last, Grand Prix to be held on the Montjuïc street circuit. The race was shortened to 29 of its scheduled 75 laps, a race distance of 109 kilometres. The race was won by German driver Jochen Mass driving a McLaren M23. It would be the only Formula One win of his career. Mass had just a second lead over the Lotus 72E of Belgian driver Jacky Ickx when the race was declared. Argentine racer Carlos Reutemann was declared third in his Brabham BT44B, a lap behind the race leaders after a penalty was given to Jean-Pierre Jarier. This was the final win by a German driver until Michael Schumacher won the 1992 Belgian Grand Prix.
First Spanish Republic
The Republic of Spain (officially in Spanish "República de España"), commonly known as the First Spanish Republic to distinguish it from the Spanish Republic of 1931–39, was the short-lived political regime that existed in Spain between the parliamentary proclamation on 11 February 1873 and 29 December 1874 when General Arsenio Martínez Campos's "pronunciamiento" marked the beginning of the Bourbon Restoration in Spain. The Republic's founding started with the abdication as King on 10 February 1873 of Amadeo I, following the , when he had been required by the radical government to sign a decree against the artillery officers. The next day, 11 February, the republic was declared by a parliamentary majority made up of radicals, republicans and democrats.
