In the fifteenth century, all three regions were making great advancement in culture and science/technology. Examples include art, architecture and exploration in Europe, Mathematics and art in the Islamic world, and new and groundbreaking inventions coming from China. We also see increased interaction and cultural exchange between the three regions through exploration and trade networks, such as the Silk Road.
However, we see divergence in power struggles between the regions, such as the battle in Spain between Islamic and Christian elements. We also see China retaining its characteristically closed nature in many ways, while Europe was increasingly looking outward and trying to establish a presence (or dominance) around the world.
