What are poll of taxes form of?

Poll taxes are a form of tax levied on individuals as a prerequisite for voting, often seen as a means to restrict suffrage. They were historically used to disenfranchise low-income individuals and marginalized groups, particularly in the United States during the Jim Crow era. Poll taxes were declared unconstitutional by the 24th Amendment in 1964 for federal elections and later invalidated by the Supreme Court for state elections in 1966.
