Arias Madrid was declared the winner of elections that were marked by violence and accusations of fraud against Alianza del Pueblo. On October 1, 1968, Arias Madrid took office as president of Panama, promising to lead a government of "national union" that would end the reigning corruption and pave the way for a new Panama. A week and a half later, on October 11, 1968, the National Guard (Guardia Nacional) ousted Arias and initiated the downward spiral that would culminate with the United States' invasion in 1989. Arias, who had promised to respect the hierarchy of the National Guard, broke the pact and started a large restructuring of the Guard. To preserve the Guard's and his vested interests, Lieutenant Colonel Omar Torrijos Herrera and Major Boris Martínez commanded another military coup against a civilian government in Panamanian republican history. (The action was reminiscent of the 1940s when strong man Colonel Jose Remon removed three duly elected presidents. Remon finally ran for president himself in 1952. He controlled the National Guard which abused the opposition during the campaign and even stole election boxes on election day.)
