Final answer:
The Democrats attempted to disenfranchise blacks through methods such as literacy tests and poll taxes, which created barriers for African Americans to register and vote.
Step-by-step explanation:
The Democrats attempted to disenfranchise blacks through a variety of methods such as implementing literacy tests, poll taxes, and property qualification laws. These tactics were designed to prevent African Americans from registering to vote by creating barriers of education, financial burden, and restrictive qualifications. For example, literacy tests required prospective voters to read and interpret complex passages, which were often more difficult for African Americans. Poll taxes were fees required to be paid before voting, which many African Americans couldn't afford. These measures were used to target and disenfranchise African Americans, effectively suppressing their political participation and power.
