Answer:
B. the shift of the Roman Empire's capital from Rome to Constantinople
Explanation:
The Western Roman Empire had been on the decline, while the Eastern Roman Empire has been on the rise. Being more powerful and more influential, the capital of the Roman Empire shifted in the Eastern part of it. Constantinople became the capital of the Roman Empire in 330 AD. This led to significant transfer of power toward the East, and big loss of power in the West. The East prospered more and more and became the strongest power in every sense in the region. The West on the other side was crumbling, little by little losing its political, economic, and military power, eventually resulting in its fall.
Manifest Destiny. Manifest Destiny was the belief that the United States was destined to extend its territory to the Pacific Ocean. ... Some Americans were opposed to manifest destiny because other nations (Mexico & Great Britain) claimed the land and because they felt an expansive nation would be too large to govern.
