What happened when Constantine tried to establish new rome?

When Constantine attempted to establish a "New Rome" by founding Constantinople in 330 AD, he aimed to create a capital that would reflect the grandeur of Rome while being strategically located at the crossroads of Europe and Asia. This new city was designed to be a center of trade, culture, and Christianity, which helped shift the focus of the Roman Empire from the western part of the empire to the east. The establishment of Constantinople eventually contributed to the decline of the Western Roman Empire, as resources and attention were increasingly directed toward the Eastern Roman Empire, which became known as the Byzantine Empire.
