Dear King Ferdinand VII, I am writing this letter to inform you that we, your Subjects, dislike some of the laws you are forcing upon us. For over 300 years now, we have been living under your tough, liable and wrongful jurisprudence. Your actions against us are quite ridiculous, and they can even be vital to our Economy. Just because you gain from your disrespectful choices, doesn’t mean that we benefit from it as humans.
Your heavy taxes can lead us to bankruptcy, and even death. Your requisite desires are causing us to not have the amount of peso (money) that we need to succeed throughout our lives. You imposing us to indemnify against our own will is discordant and barbarous. Rebelling against you has never been as paramount until the present.
Due to your childish-like manners, and us using our hard-earned peso for stuff that we can’t even use for our own families, the time for us to dawn is now.
I, Miguel Hidalgo, hereby declare that from now on we will hold a war against those who choose to be selfish with you. I will lead us through these tough struggles and proclaim this war to be the war that gains us our independence.
I do believe that this is worth dying for. Any chance to get autonomy may always lead to demise, but it is worth it. Independence means happiness for all, and that’s what I want for my people. Feel free to press charges against me, but I will do this for myself and for those who choose to rebel alongside me.

Sincerely,
Miguel Hidalgo

Does this seem good for a high grade? I feel like I should edit it, but I’m not sure of what to add.
