Who attempted to address the decline of the Roman Empire through reforms but only achieved partial success?

The person who attempted to address the decline of the Roman Empire through reforms but only achieved partial success was Emperor Diocletian.

1. Diocletian became the Roman Emperor in 284 AD, during a period of political instability and economic crisis, often referred to as the Crisis of the Third Century.

2. Recognizing the vastness and diversity of the Roman Empire, Diocletian decided to divide the empire into two parts in 285 AD - the Eastern Roman Empire and the Western Roman Empire. This was known as the Diocletian's Tetrarchy.

3. He also introduced economic reforms, including the Edict on Maximum Prices in 301 AD, which was an attempt to control inflation by setting maximum prices and wages throughout the Empire.

4. Diocletian's reforms brought some stability and prosperity back to the Empire, but they were not enough to stop the eventual fall of the Western Roman Empire in 476 AD.

5. Therefore, while Diocletian's reforms did achieve some success in addressing the decline of the Roman Empire, they were only partially successful in the long run.
