How do I gain followers in 5e like I did in AD&D?

I just started playing D&D 5th edition at college with friends after playing AD&D for years with my family in a homebrew campaign. I just noticed that fighters don’t get any followers after getting to level 9 in 5th edition. Are there any mechanics for having followers in 5th edition?
I’m playing a noble dwarf so I was hoping to have a small army after level 9.
