Soria is a city in north-central Spain, the capital of the province of Soria in the autonomous community of Castile and León. As of 2010^[update], the municipality has a population of c. 39,500 inhabitants, nearly 40% of the population of the province. Situated on the Rio Duero in the east of the autonomous community, the city is noted for its walls and a number of architecturally distinctive churches.

It is claimed that in Roman times there was a castle called Oria, purportedly named after a Greek knight called Doricus. Based on this folk etymology, some historians guessed that the first inhabitants of this city might have been the Dorians. Archaeology has not confirmed that story. Instead it has suggested that the first inhabitants were the Suebi, whose kings (as reported by Tutor and Malo in their Compedio historial de las dos Numancias) established one of their courts in Soria. These two hypotheses have been abandoned because of lack of evidence. It seems more likely that the name Soria may have its origin in the word dauria from the river Durius (Duero).

Paulino Iglesias Posse (October 18, 1850 – December 9, 1925), better known as Pablo Iglesias, was a Spanish socialist and labour leader. He is regarded as the father of Spanish socialism; having founded the Spanish Socialist Workers' Party (PSOE) in 1879 and the Spanish General Workers' Union (UGT) in 1888.

Iglesias was born to humble parents who called him Paulino. He attended school between the ages of six and nine, when his father, a municipal laborer, died. Pablo, his younger brother, and their mother put their possessions in a small covered cart and walked with it to live in Madrid. Pablo's mother survived there by begging, and both boys entered the Hospicio of San Fernando. They completed primary schooling there, and Pablo learned printing. Aged twelve he left the Hospicio to work and to help support his mother. He worked as a printer, gradually improving his wages. While he was rendered unemployed by a strike, his brother died of tuberculosis.

He attended evening classes and learned French. This let him read classic works of French political science, translate the works of French socialists and participate successfully in international congresses. Protected by the 1869 Constitution, the Spanish section of the International Workers Association (AIT) organized a series of conferences in Madrid. Iglesias attended, and in 1870, was invited to enter the printers section. The appearance of Solidarity, newspaper of the International, started him on the intense journalistic career that occupied the rest of his life.

Carlos Ernesto Soria (March 1, 1949 – January 1, 2012) was an Argentine lawyer and Justicialist Party politician. He died in the early hours of January 1, 2012, from a gunshot wound, at his farm, after the New Year celebrations. Soria was the governor of Rio Negro Province at the time. His widow was charged with first-degree murder on January 19, 2012.

Soria was born in Bahía Blanca in 1949, and was raised in a nearby rural town, General Daniel Cerri. His father, Ernesto Soria, was an outspoken Peronist, and was arrested shortly after the 1955 coup against President Juan Perón. Following his release several months later, the Sorias relocated to Bariloche. The elder Soria was again arrested amid a crackdown on Peronist protests during a state visit to Bariloche by U.S. President Dwight Eisenhower in March 1959, and was imprisoned in Bahía Blanca. He was released in April 1962 and the family settled in General Roca, Río Negro, where they opened a neighborhood store.

Carlos Soria enrolled at the University of Buenos Aires, earning a Law degree in 1973. Elections that March returned Peronists to power, and Soria was elected to the local Justicialist Party (JP) chapter. He was later elected to the Provincial Council of the JP, and upon the return of democracy in 1983, won a seat in the Argentine Chamber of Deputies.
