What fundamental law was modified by the Augusta convention in 1788?

The fundamental law that was modified by the Augusta convention in 1788 is indeed the original state constitution. During this convention, delegates gathered to address significant governance issues in Georgia and sought to amend the state constitution to reflect new political realities and incorporate better governance structures. This was particularly important as the state was adapting to changes following the American Revolution and in anticipation of a stronger federal framework.

The original state constitution was the foundational governing document for Georgia before the advent of the amendments and restructuring that took place during the convention. The changes made were intended to enhance the effectiveness of the state's government and align Georgia more closely with evolving democratic principles and practices.

In this context, while the Articles of Confederation and the federal Constitution were important documents during that period, they were not modified at the Augusta convention. Additionally, the Bill of Rights is specific to the federal Constitution and was adopted later, thus it does not pertain to the changes made by this convention.
