According to the dictionary, a constitution is a set of fundamental principles or established precedents according to which a state or other organization is governed. These rules together make up, what the entity is. When these principles are written down into a single collection or set of legal documents, those documents may be said to comprise a written constitution.
So as you can see a constitution is a set of rules and principles that should be respected in every country. It differs from country to country
The first constitution was written in 621 BC in Athens, it was named "Draco", and it was the very first constitution that was written.
Let’s talk a little bit about Egypt. I think that Egypt right now is experiencing a very tough time, that’s why it will be better if people write the constitution before the presidential elections. Because right now the Egyptians are not ready at all for presidential elections. And people are actually not so sure about what they want for their country right now. That’s why the constitution must be written before the elections. May god bless Egypt!
