this day. Europe In post-World War II Europe, revolutionary songs were taught in schools and sung at celebrations and official functions. China Revolutionary songs were a prominent part of the popular culture of the People's Republic of China during the 1950s, 1960s, and 1970s, and especially during the Cultural Revolution. One of the more popular Chinese revolutionary songs was "Nanniwan", a 1943 song lauding the exploits of the Eighth Route Army in the titular gorge in Shaanxi province near the revolutionary base of Yan'an. Revolutionary songs of Communist China often served to glorify the 1949 revolution and to present an image of unity amongst China's 56 ethnic groups and its various regions. Songs such as "The Sky Above the Liberated Zone" (praising the Communist Party of China and romanticizing life in the CCP-held liberated zones during the wars against Japan and the Kuomintang) and "Osmanthus Flowers Blooming Everywhere in August", a Red Army folk song from the Sichuan province, are among the best-known revolutionary songs from the wartime and Maoist periods in China. North Korea Vietnam Nhạc đỏ, "Red Music," is the common name of the revolutionary music (nhạc cách mạng) genre in Vietnam. Composers during the struggle against the French include Đinh Nhu then songwriters of Vietnamese popular music such as Văn Cao. Cuba and Latin America Cuba's national anthem "La Bayamesa (El Himno de Bayamo)" dates to 1868, but many new songs were generated by the revolution. The key focus is on the rural people. "Hasta siempre" (1965) was written when Che Guevara departed Cuba to spread the revolution in Africa. Another well known Latin American song, "El pueblo unido jamás será vencido" (1973), is not a revolutionary song, but a Chilean protest song in support of Salvador Allende. Cuban government sponsored revolutionary Nueva trova is often similar to Nueva canción, Latin American protest songs. Iranian revolution Following the Iranian revolution musicians were obliged to create music different from the pre-revolutionary music both in terms of rhythm and content. Iranian revolutionary songs () are epic ballads, composed during the Islamic Revolution in Iran in support of the revolution and in opposition to the Pahlavi dynasty. Before the success of the revolution, these chants were made by various political supporters- many of them recorded on cassette tapes in underground and home studios. On the anniversary of the revolution, many of the songs were broadcast by Iranian state television. In
