María Magdalena Nile del Río (26 December 1906 - 22 August 2003) was an Argentine professional singer and movie actress, better known as Imperio Argentina; she became a citizen of Spain in 1999.
María Magdalena Nile del Río was born to Antonio Nile (a guitar player, born in Gibraltar) and Rosario del Río (a native of Monda in the Province of Málaga). She performed onstage in her native Argentina, where she had a long and successful career. At that time, her stage name was Pettit Imperio. But her most successful moments came after she moved to Spain. It was there that she changed her name to Imperio Argentina, as a way to honor her "other country". While in Spain, del Río acted in many movies, and frequently worked in television and radio. She obtained Spanish citizenship in 1999.[1]
In January 2003, she suffered an angina attack and was admitted to the University Hospital of Malaga. She died in Benalmádena in the Province of Málaga (her mother was born and raised in the same province) in August 2003, aged 97. She had two children. Her son, Florián Antonio Martínez Nile, by her marriage to Florián Rey, predeceased her, having committed suicide at age 24 in 1959. Her younger child was her daughter, Alejandra Goyanes Nile, by another marriage. She was married twice. As a divorcee, she could not, in Francoist Spain, legally marry Joaquín Goyanes, the father of her daughter.[2]
