Hello! I know there's a lot of people on here who would know this stuff, I would appreciate any info on how some of this stuff worked.

1. How did ancient republics raise armies? I understand that there may have been many different procedures in different time frames. From what I understand, in a feudal system, lords would raise soldiers from their respective fiefs. Any different methods that were used for either Rome/Carthage would be great.

2. What role did the Patrician family's play? Did they own land they were responsible for protecting/paying taxes on? I understand the feudal system a little better, and I'm interested in the differences.

3. Were non patricians allowed to own land? If so on what scale?

Thanks for any info, feel free to endow me with any other interesting knowledge about how these governments functioned.
