The Catalan Revolt (Catalan: Guerra dels Segadors, Eastern Catalan: [ˈɡɛrə ðəɫs səɣəˈðos], Western Catalan: [ˈɡɛrɛ ðeɫs seɣaˈðos]; meaning in English "Reapers' War") affected a large part of the Catalan Principality of Catalonia between the years of 1640 and 1659. It had an enduring effect in the Treaty of the Pyrenees (1659), which ceded the county of Roussillon and the northern half of the county of Cerdanya to France (see French Cerdagne), thereby splitting the Catalan population of the Aragonese crown.

The war had its roots in the discomfort generated in Catalan society by the presence of Castilian troops during the wars between France and Spain as part of the Thirty Years' War. Count-Duke Olivares, the chief minister of Philip IV, had been overusing Catalan resources in his wars against France. Catalan peasants, who were forced to quarter Castilian troops, responded on Corpus Christi day, May 1640, with an uprising known as 'Bloody Corpus' (Catalan Corpus de Sang), under the slogans "Long live the faith of Christ!", "Long live the king , our lord", "Long live the land, death to bad government". This 'Bloody Corpus' which began with the death of a segador, a reaper,^{[citation needed]} and led to the somewhat mysterious death of Dalmau de Queralt, Count of Santa Coloma and Spanish viceroy of Catalonia, marked the beginning of the conflict. The irregular militia involved were known as 'Miquelets'.

Charles Edward Haden (born August 6, 1937) is an American jazz musician. He is a double bassist, probably best known for his long association with saxophonist Ornette Coleman. Haden is also known for his signature lyrical bass lines.

Haden was born in Shenandoah, Iowa, and raised in a musical family, which often performed together on the radio playing country music and American folk songs. Haden made his professional debut as a singer when he was two years old, and continued singing with his family until he contracted a mild form of polio when he was 15. The polio damaged his throat muscles and vocal cords, and as a result, Haden was unable to control his pitch while singing. A few years before contracting polio, Haden had become interested in jazz, and began playing his older brother's double bass. Eventually he set his sights on Los Angeles, and to save money for the trip took a job as house bassist for ABC-TV's Ozark Jubilee in Springfield, Missouri.

Haden moved to Los Angeles in 1957. His first recordings were made that year with Paul Bley. He began recording with Ornette Coleman shortly after, including the important The Shape of Jazz to Come. Haden's folk-influenced style complemented the microtonal, Texas blues elements of Coleman. Haden would enter Keith Jarrett's trio and his 'American Quartet' from 1967 to 1976 with Paul Motian and Dewey Redman. He also played in the collective Old and New Dreams.
