Question: How many months after the start of the Civil War was Alvarez killed? Passage 1:William "Billy" Walsh (31 May 1921 – 28 July 2006), also referred to as Willie Walsh, was an Irish footballer. Walsh played for several clubs, but most notably with Manchester City, for whom he made more than 100 appearances. As an international, Walsh represented four national teams: after playing for the England Schoolboys XI, he then became a dual Irish international, playing for both Ireland teams – the FAI XI and the IFA XI. In 1949, he was a member of the FAI XI that defeated England 2–0 at Goodison Park, becoming the first non-United Kingdom team to beat England at home. He then emigrated to New Zealand and also played in an unofficial game for their national team. Walsh eventually moved to Australia and settled in Noosa, Queensland. In 2003, he and several other former Manchester City players returned for the last game at Maine Road. He died on 28 July 2006 at the age of 85 and his ashes were interred at the Garden of Remembrance at the City of Manchester Stadium.

In 1898 he was elected to the Congress as Liberal candidate and was appointed Professor of Roman Law at the University of Oviedo.

He was one of the organizers of the Liberal Block in 1908 against the Conservative Prime Minister Antonio Maura and of the Republican-Socialist Conjunction in 1909. In 1912, he founded with Gumersindo de Azcárate and José Ortega y Gasset the Reformist Party and the League for the Spanish Political Education. In the 1914 elections, 11 Reformist congressmen were elected. It had also a great success in the municipal elections in Asturias. During the Second Republic he founded the Democratic Liberal Republican Party (Partido Republicano Liberal Democrático), but its electoral results were poor: two deputies in 1932 and ten in 1933, when they supported the right-wing government backed by the Spanish Confederation of the Autonomous Right (CEDA). After the beginning of the Civil War, the revolutionary militias imprisoned and killed him.
