Declaration: A declaration is another type of formal statement but typically carries more weight than a resolution. It often signifies the establishment of something new, like the Declaration of Independence that declared America's independence from Britain.
Proclamation: Similar to resolutions and declarations, proclamations are official statements made by authorities or governments. They are usually used to announce important events, policies, or laws.
Petition: A petition is a formal request signed by many people asking for specific action from someone in authority. It's like signing an online petition to support a cause you care about.
