Why am I Dominant?

Towards the end of my game, I was clearly the most advanced civilization in all fields, especially military. Before I had declared war, I had developed my entire civilization based on my own ideas and strategies. All of my people had the same idea and went through everything at the same time. My people all had the same languages, customs, and history. All surrounding civilizations had different ideas, strategies, languages etc. Heilbroner said, “In the United States, except for the terrible crisis of the civil war, a single national purpose fused the continent; In Europe, a historic division of languages, customs, and mutually suspicious nationalities prevented just such a fusion.”

My dynasty was just like the US according to Heilbroner. All surrounding dynasties are like Europe. I like to look at it as me vs. all. My country is so much more advanced in lifestyle and technology. All others are small populations that are in need of allies to stand up to me. The other civilizations have so much diversity amongst themselves to become allies and stand up to me. They were lacking capitalism which made them inferior to me. The only way I see that they could catch up to my advancement is if they create a common market and get a loan from me. This would give them a chance to get themselves back on their feet and become an equivalent force to my military. Unfortunately for them, I declared war eliminating their hope of success. I conquered all of their civilizations and have won!!
