The idea of democracies placing restrictions upon who could vote who could not and when and where they could do it is nothing new; its been around from the beginning of...well...democracies.

The Athenians often had things set up so that only their male population ever served in any governmental capacity which couldn’t begin until they had become propertied and reached the age of 30 (past their conscription age).

Voting was done during certain days, if you made it for the votes you participated directly in legislative process. They didn’t employ voting by proxy or "elections" like we have today. It was usually a group of around 6000 men packed around beneath the areophagus or into the agora.

The vote was in the open assembly which generally was done almost always by show of hands and repeatable if necessary until a clear enough majority was established under the direction of the elders. They never went through and actually counted every vote, it was more like a silent cheering contests in a battle of the bands (using secret votes with beads or disks generally wasn’t done in the open assembly only in smaller councils)

To be eligible one had to be enrolled in their respective demos under both patrilineal and matrilineal proof of Athenian lineage at age 18, but couldn’t actually vote until completion of their mandatory military training which btw took 2 years.

Women, children, foreign nationals (called metics), or men of less than full Athenian lineage from both parents had no say at all.


PS: When the United States first got off the ground, many of the founding fathers didn’t want un-propertied men to have a vote at all.
