He and his escort of sailors were killed by natives when they went ashore for water. The few remaining sailors brought the ship and its story back to Cortés. There is some dispute whether the land was named at this time—no record exists of Ximénez giving it a name. In 1535, Cortés led an expedition back to the land, arriving on May 1, 1535, a day known as Santa Cruz de Mayo, and in keeping with methods of contemporary discoverers, he named it Santa Cruz. It is not known who first named the area California but between 1550 and 1556, the name appears three times in reports about Cortés written by Giovanni Battista Ramusio. However, the name California also appears in a 1542 journal kept by explorer Juan Rodríguez Cabrillo, who used it casually, as if it were already popular. In 1921, California historian Charles E. Chapman theorized that Ximénez named the new land California but the name was not accepted by Cortés because Ximénez was a mutineer who killed Becerra, a kinsman of Cortés. Despite this, the name became the one used popularly by Spaniards, the only name used by non-Spaniards, and by 1770, the entire Pacific coast controlled by Spain was officially known as California. The Spanish-speaking people who lived there were called Californios. For many years, the Rodríguez de Montalvo novel languished in obscurity, with no connection known between it and the name of California made by English-speaking American settlers. In 1864, a portion of the original was translated by Edward Everett Hale for The Antiquarian Society, and the story was printed in the Atlantic Monthly magazine. Hale supposed that in inventing the names, Rodríguez de Montalvo held in his mind the Spanish word calif, the term for a leader of the Muslim people. Hale's joint derivation of Calafia and California was accepted by many, then questioned by a few scholars who sought further proof, and offered their own interpretations. George Davidson wrote in 1910 that Hale's theory was the best yet presented, but offered his own addition. In 1917, Ruth Putnam printed an exhaustive account of the work performed up to that time. She wrote that both Calafia and California most likely came from the Arabic word khalifa which means ruler or leader. The same word in Spanish was califa, easily made into California to stand for "land of the caliph", or Calafia to stand for
