After the Tragic Week of 1909, the Spanish government starting in 1911 tried to raise as many Regulare units as possible to avoid further working class resistance to colonial wars as much of the Spanish working class had no desire to see their sons sent to Morocco, beginning a policy of what the Spanish historian Jose Alvarez called "Moroccanizing" the conquest of the Rif. Following the difficulties and setbacks that it had experienced in 1909-11, the Spanish army began to adopt much in organization and tactics from the French North African forces garrisoning most of Morocco and neighboring Algeria. Particular attention was paid to the French Foreign Legion and a Spanish equivalent, the Tercio de Extranjeros , known in English as the "Spanish Legion", was formed in 1920. The regiment's second commander was then-Col. Francisco Franco, having risen rapidly through the ranks. In the Rif war, it was the Regulares and the Spanish Foreign Legion founded in 1919 that provided the elite forces that won Spain the war. Less than 25% of this "Foreign Legion" were, in fact, non-Spanish. Harshly disciplined and driven, they quickly acquired a reputation for ruthlessness. As their number grew, the Spanish Legion and the Regulares increasingly led offensive operations after the disasters that had been suffered by the conscript forces.
