California Proposition 5 (1916)
From Ballotpedia
Proposition 5 appeared on the ballot in California in 1916 as an initiated constitutional amendment. Its goal was to declare that all public revenues be raised by taxation of land values (as opposed to other forms of taxation), and that the tax could only be levied on the value of the land, not on any land improvements, such as buildings.
It was defeated at the polls.
