Rutherford centralized organizational control of the Watch Tower Society. In 1919, he instituted the appointment of a director in each congregation, and a year later all members were instructed to report their weekly preaching activity to the Brooklyn headquarters. At an international convention held at Cedar Point, Ohio, in September 1922, a new emphasis was made on house-to-house preaching. Significant changes in doctrine and administration were regularly introduced during Rutherford's twenty-five years as president, including the 1920 announcement that the Jewish patriarchs (such as Abraham and Isaac) would be resurrected in 1925, marking the beginning of Christ's thousand-year Kingdom. Disappointed by the changes, tens of thousands of defections occurred during the first half of Rutherford's tenure, leading to the formation of several Bible Student organizations independent of the Watch Tower Society, most of which still exist. By mid-1919, as many as one in seven of Russell-era Bible Students had ceased their association with the Society, and as many as two-thirds by the end of the 1920s.

What did Rutherford institute the appointment of in each congregation in 1919?

The uneasy alliance of Carranza, Obregon, Villa, and Zapata eventually led the rebels to victory.

On August 20, 1914, Carranza made a triumphal entry into Mexico City. Carranza (supported by Obregon) was now the strongest candidate to fill the power vacuum and set himself up as head of the new government. This government successfully printed money, passed laws, etc.

Who made a triumphant entry into Mexico City on August 20, 1914?

The mandolin's popularity in the United States was spurred by the success of a group of touring young European musicians known as the Estudiantina Figaro, or in the United States, simply the "Spanish Students." The group landed in the U.S. on January 2, 1880 in New York City, and played in Boston and New York to wildly enthusiastic crowds. Ironically, this ensemble did not play mandolins but rather bandurrias, which are also small, double-strung instruments that resemble the mandolin. The success of the Figaro Spanish Students spawned other groups who imitated their musical style and costumes. An Italian musician, Carlo Curti, hastily started a musical ensemble after seeing the Figaro Spanish Students perform; his group of Italian born Americans called themselves the "Original Spanish Students," counting on the American public to not know the difference between the Spanish bandurrias and Italian mandolins. The imitators' use of mandolins helped to generate enormous public interest in an instrument previously relatively unknown in the United States.

What group was inspired by the Estudiantina Figaro?
Answer:
Original Spanish Students
