I am doing a project for school and I was wondering if someone could help me. I'm trying understand what the difference between a Duke, Earl, Baron, Viscount and (I don't know if I'm spelling this right but) Marquess.
What does each title mean? How do responsibilities differ and does each area (like Warwick) for example have a Duke, Earl, Viscount ect. of Warwick? And how would someone's standing at court be affected by their status.
