Question

How did voting requirements change in the 1800’s

Answer 1

Men didn't have to own land anymore to vote, also, political parties had nominating conventions to select candidates. Something else is that some states extended suffrage to more Caucasian males. 

Answer 2

I may be wrong, but I do believe this may have to do with Andrew Jackson's election, and the voting requirements changed because you no longer had to own property or be wealthy to vote. The common, free white man could vote.
