Question: When was the Empire that dominated the People of Totanac ethnicity formed? Passage:Totonacapan refers to the historical extension where the Totonac people of Mexico dominated, as well as to a region in the modern states of Veracruz and Puebla. The historical territory was much larger than the currently named region, extending from the Cazones River in the north to the Papaloapan River in the south and then west from the Gulf of Mexico into what is now the Sierra Norte de Puebla region and into parts of Hidalgo. When the Spanish arrived, the Totonac ethnicity dominated this large region, although they themselves were dominated by the Aztec Empire. For this reason, they allied with Hernán Cortés against Tenochtitlán. However, over the colonial period, the Totonac population and territory shrank, especially after 1750 when mestizos began infiltrating Totonacapan, taking political and economic power. This continued into the 19th and 20th centuries, prompting the division of most of historical Totonacpan between the states of Puebla and Veracruz. Today, the term refers only to a region in the north of Veracruz were Totonac culture is still important. This region is home to the El Tajín and Cempoala archeological sites as well as Papantla, which is noted for its performance of the Danza de los Voladores.

Question: How long had Jimmy Palao been playing violin for the year Dodds moved to California? Passage:Dodds gained a reputation as a top young drummer in New Orleans. In 1918, Dodds left Sonny Celestin's outfit to play in Fate Marable's riverboat band. A young Louis Armstrong also joined the band, and the two of them were on the boats for three years (from 1918 to 1921). The band played on four different boats, and usually left New Orleans in May and travel to St. Louis, though they also sometimes traveled further north. They played jazz, popular, and classical music while on the boats. Dodds and Armstrong left Fate Marable's band in 1921 due to a disagreement about musical style, and Dodds soon joined King Oliver's Creole Jazz Band. At this time, the personnel in Oliver's band were Joe "King" Oliver on cornet, Baby Dodds' brother Johnny Dodds on clarinet, Davey Jones on alto saxophone, Honoré Dutrey on trombone, Lil Hardin on piano, Jimmy Palao on violin, and Eddie Garland on bass fiddle. They moved to California in 1921 to work with Oliver there, and they played together for about fifteen months. In 1922, the band, excepting Garland, Palao, and Jones, followed Oliver to Chicago, which would be his base of operations for several years. They began playing at the Lincoln Gardens, and Louis Armstrong also joined this outfit. Dodds describes playing with this band as "a beautiful experience". Dodds recorded with Louis Armstrong, Jelly Roll Morton, Art Hodes, and his brother Johnny Dodds. Dodds played in Louis Armstrong's Hot Five and Hot Seven groups. In May 1927 Armstrong recorded with the Hot Seven, which consisted of Johnny Dodds, Johnny St. Cyr, Lil Hardin Armstrong, John Thomas, Pete Briggs, and Baby Dodds. From September to December 1927 the Hot Five Armstrong assembled consisted of Johnny Dodds, Kid Ory, Johnny St. Cyr, Lonnie Johnson, and Baby Dodds.
