ProEnglish was a major backer of the unsuccessful 2009 Nashville Charter Amendment 1, a local "English First" ballot referendum in Nashville, Tennessee, which would have generally required government communication and publications to be printed in English only. ProEnglish donated $82,500, about 92% of the total amount raised by the referendum's supporters. The referendum was rejected by Nashville voters. In 2012, ProEnglish was the leading force behind a successful effort to make English the official language of Frederick County, Maryland; the county enacted an ordinance closely based on one drafted by the group. However, in 2015, the country repealed the ordinance, marking a defeat for the organization.
