    Society of St. Tammany founded

    William Mooney and other veterans founded the Society of St. Tammany in New York City as a fraternal and patriotic club, named for a legendary Delaware chief. It began as a social and charitable organization with no formal political role, but its lodge structure and networks of local ward captains made it a natural vehicle for organizing voters.

    Aaron Burr used the Society of St. Tammany's ward networks to mobilize Democratic-Republican voters in New York City, helping deliver the state's electoral votes and contributing to Thomas Jefferson's victory. Historians treat this as the first clear demonstration of Tammany's value as an electoral machine rather than a purely social club.

    As police commissioner, Roosevelt ordered strict enforcement of the state excise law requiring saloons to close on Sundays, a law police captains had long ignored in exchange for bribes.

  24. new

    Roosevelt resigns as Police Commissioner
