districts developed around former camps in East and North Nashville. In the late 1880s, its African-American and poor white populations were affected by changes to laws by the state legislature, which made voter registration and voting more difficult by requirements including imposition of a poll tax in 1889. The effect was to disenfranchise most blacks and many poor whites, after Tennessee had been one of the most competitive states politically after the Civil War. About one-third of the state's citizens were thus shut out of the political process, a status that lasted for decades, until after passage of legislation during the mid-1960s as a result of the civil rights movement. In 1897, Nashville hosted the Tennessee Centennial and International Exposition, a World's Fair celebrating the 100th anniversary of Tennessee's entry into the Union. A replica of the Parthenon was built for the event. The Parthenon replica is now the centerpiece of Centennial Park. An interesting sidenote occurred during the administration of Theodore Roosevelt. President Roosevelt visited Nashville and took his lodging at the Maxwell House Hotel. Joel Cheek, proprietor thereof, had served a special blend of coffee at the hotel's restaurant, and after drinking a cup of this coffee, Roosevelt proclaimed it "good to the last drop!" Cheek subsequently sold the blend to General Foods and to this day, Maxwell House coffee is enjoyed by millions. In 1913 Nashville was the last of several major cities in Tennessee to adopt a commission form of government, with all members of a small commission elected at-large. Compared to single-member districts, this change resulted in further limiting the political power of any African Americans who were able to vote, as their candidates were unable to gain support by the majority of the city, which was white. Other cities that adopted this form of government in this period were Clarksville in 1907, Chattanooga and Knoxville in 1911, and Jackson in 1915. As a result of legal challenges beginning in the late 1970s, all these cities have adopted new systems, most by 1990. These established council or commissions with more numerous members, most of whom are elected from single-member districts, when enables minorities to elect one or more candidates of their choice. On March 22, 1916, a fire in East Nashville erupted, destroying more than 500 homes. The fire was exacerbated by unusually high wind gusts, allowing it to spread quickly before firefighters could suppress
