What is widely regarded as the first written constitution in history?

Explanation: Meesaq-e-Madina (Charter of Madinah) is widely regarded in Islamic history as one of the earliest written constitutions. It was established by Prophet Muhammad (ﷺ) after his migration to Madinah and outlined the rights, responsibilities, and mutual obligations of the various communities living in the city. The charter promoted justice, cooperation, religious freedom, and collective security, making it a landmark document in constitutional and political history.
