Puerto Rico at the 1948 Summer Olympics

The first Olympic participation took place at London 1948.^[3] Prior to the games, the topic of which flag was to be used was contentious.^[4] Despite being tasked with reorganizing the Puerto Rico Olympic Committee, Julio Enrique Monagas opposed the participation of Puerto Rico in the games at first.^[5] However, his work in the games, which included mingling with representatives of other countries, would be praised afterwards.^[5] After participating under the United States flag favored by the colonial government at the 1946 Central American and Caribbean Games, a new flag bearing the Coat of Arms was used in 1948.^[4] Since the American delegation was already present in the event, duplicity was to be avoided.^[4] However, at London bearer Miguel A. Barasorda demanded that he was allowed to exhibit the flag of Puerto Rico, with Monagas claiming that Luis Muñiz Marín had banned its use.^[6] This led to José Vicente becoming the last moment replacement.^[4]

On July 16, 1947, Monagas made his ignorance of IOC practices obvious when he sent a letter admitting that the local committee was a government entity, at a time when political involvement was prohibited by the organization.^[7] On September 17, 1947, he requested affiliation to the IAAF.^[7] Otto Mayer demanded that it complied with protocol in a reply to the first letter sent a week later.^[7] On October 1, Ernest J.H. Holt echoed this stance on behalf of the IAAF.^[7] In January 1948, Puerto Rico's application was favorably received despite being affiliated to the government, giving birth to the COPUR.^[8] At the United States, this caused some controversy along the likes of Dan Ferris. On March 25, 1948, Puerto Rico was invited to the London Games.^[9] On April 15, 1948, the United States opposed the invitation.^[10] This stance was later reversed, under unknown conditions.

At the Puerto Rico House of Representatives funding of $10,000 was approved for the Games, but governor Jesús T. Piñero vetoed it.^[11] Despite causing controversy, Monagas sided with the governor.^[11] As a civilian initiative was being organized, the politicians reversed their stance and supported sending the delegation to London.^[11] However, a small delegation was sent as a formality, with no expectation of winning medals.^[12] Monagas himself led the group, accompanied by trainer Eugenio Guerra.^[13] The participation of Puerto Rico at the event gathered considerable media coverage from the likes of El Mundo.^[13] A parallel political debate was waged in the media.^[14] Upon the delegation's return, Piñero's stance had shifted to one of support for future participation in the Olympics.^[15]
