but the Democratic-dominated state legislature obstructed any attempt at an investigation. The most notable event of Taylor's second term as governor was the Tennessee Centennial, which marked the 100th anniversary of the state's admission to the Union. The state celebrated by producing the Tennessee Centennial and International Exposition, a five-month world's fair held in Nashville's Centennial Park in 1897, with Taylor making numerous appearances. Later life After his final term as governor, Taylor returned to the lecture circuit, though he continuously sought one of the state's US Senate seats, then elected by the legislature. In 1907, he defeated the incumbent Senator Edward W. Carmack in a public primary, and Taylor was elected by the state legislature to the seat later that year. He served from 1907 until his death in 1912. Some of the legislation that he supported was the Sixteenth Amendment, which authorized the federal government to levy income taxes. He helped secure the amendment's passage in the Senate in 1909. In 1910, when incumbent Democratic Governor Malcolm R.

He lost in the general election to the Republican nominee, Ben W. Hooper, who had defeated Taylor's brother, Alfred, for the Republican nomination earlier that year. On March 31, 1912, Taylor suffered a gallstone attack and died following unsuccessful surgery at Providence Hospital in Washington. A specially chartered train carried his body to Nashville, where it lay in the capitol for several days. It was then taken to Knoxville, where a funeral procession of more than 40,000 people, the largest in the city's history, attended his burial at Old Gray Cemetery. The remains of both Robert Love Taylor and his wife, Sarah Elizabeth Halbert Taylor, were removed from the Old Gray Cemetery in Knoxville on October 5, 1938 and later interred at the Monte Vista Memorial Park in Johnson City, Tennessee. Family Taylor's great-grandfather, General Nathaniel Taylor (1771–1816), served during the War of 1812. Another great-grandfather, Landon Carter (1760–1800), was a Revolutionary War veteran for whom Carter County was named. Taylor's father, Nathaniel Green Taylor (1819–1887), served two terms in Congress (1853–1855 and 1866–1867), and published poetry and religious essays. Taylor's brother, Alfred, served three terms in the U.S. House of Representatives (1889–1895), and one term as Governor of Tennessee (1921–1923). Nathaniel Edwin Harris, who served
