Question: During the May Event, what was the part of Catalonia controlled by the anarchists called?

<P0-S0>  These included the Confederación Nacional del Trabajo (CNT, National Confederation of Labor) which was the dominant labor union at the time and the closely associated Federación Anarquista Ibérica (FAI, Iberian Anarchist Federation). <P0-S1>  The Unión General de Trabajadores (General Worker's Union), the POUM and the Unified Socialist Party of Catalonia (which included the Communist Party of Catalonia) were also involved. <P0-S2> Revolutionary Catalonia (July 21, 1936 – 1939) was the part of Catalonia (an autonomous region in northeast Spain) controlled by the anarchist, communist, and socialist trade unions, parties, and militias during the Spanish Civil War. <P0-S3>  Although the Generalitat of Catalonia was nominally in power, the trade unions were "de facto" in command of most of the economy and military forces. <SEP> <P1-S0> The May Days of 1937, sometimes also called May Events, referring to a series of clashes between 3 and 8 May 1937, were a period of civil violence in Catalonia, when factions of the Republican side engaged each other in street battles in various parts of Catalonia, in particular in the city of Barcelona, during the Spanish Civil War. <SEP> <P2-S0> The National Cherry Festival is a festival in Traverse City, Michigan. <P2-S1>  It began in 1925 as the Blessing of the Blossoms Festival, which was held in early May to attract tourists to Northern Michigan to view the blooming cherry blossoms. <P2-S2>  In 1931 the Michigan Legislature renamed the festival to the National Cherry Festival, and moved the event to the summer. <P2-S3>  Since 2004, a May event coinciding with blooming of the cherry blossoms is also held again, as the Blossom Days Festival, in addition to what is now the better-known National Cherry Festival. <SEP> <P3-S0> The background of the Spanish Civil War dates back to the end of the 19th century, when the owners of large estates, called "latifundia", held most of the power in a land-based oligarchy. <P3-S1>  The landowners' power was unsuccessfully challenged by the industrial and merchant sectors. <P3-S2>  In 1868 popular uprisings led to the overthrow of Queen Isabella II of the House of Bourbon. <P3-S3>  In 1873 Isabella's replacement, King Amadeo I of the House of Savoy, abdicated due to increasing political pressure, and the short-lived First Spanish Republic was proclaimed. <P3-S4>  After the restoration of the Bourbons in December 1874, Carlists and anarchists emerged in opposition to the monarchy. <P3-S5>  Alejandro Lerroux helped bring republicanism to the fore in Catalonia, where poverty was particularly acute. <P3-S6>  Growing resentment of conscription and of the military culminated in the Tragic Week in Barcelona in 1909. <P3-S7>  After the First World War, the working class, the industrial class, and the military united in hopes of removing the corrupt central government, but were unsuccessful. <P3-S8>  Fears of communism grew. <P3-S9>  A military coup brought Miguel Primo de Rivera to power in 1923, and he ran Spain as a military dictatorship. <P3-S10>  Support for his regime gradually faded, and he resigned in January 1930. <P3-S11>  There was little support for the monarchy in the major cities, and King Alfonso XIII abdicated; the Second Spanish Republic was formed, whose power would remain until the culmination of the Spanish Civil War. <P3-S12>  Monarchists would continue to oppose the Republic.
