Asking for help with your homework is indeed against our submission rules. /r/HomeworkHelp might be a better place for this.

Hello! We don't allow homework questions here. Please use /r/HomeworkHelp

Our users aren't here to do your homework for you, but they might be willing to help. Remember: AskHistorians helps those who help themselves. Don't just give us your essay/assignment topic and ask us for ideas. Do some research of your own, then come to us with questions about what you've learned. This is explained further in this [META] thread.

I know this is against submission rules but it is for a class.

Yet you do it anyways... Feel free to ask questions about Alexander or about Caesar, but we aren't here to do your comparison for you.
