A proclamation is like when your teacher announces something really important to the whole class. It's a fancy way of making an announcement that everyone needs to pay attention to. It's usually used by important leaders like a king, queen, or president to make an official announcement about something that's really important to them or their country. For example, a king might make a proclamation to celebrate a special day like a holiday or to declare war on another country. It's like they are speaking to everyone and telling them what they want them to know. And just like your teacher's announcement, everyone needs to listen carefully to what the proclamation says.
