Which of the following is considered the first international style since the Roman Empire?

The Romanesque style is considered the first international style since the Roman Empire due to its widespread influence across different regions of Europe during the 9th to 12th centuries. This architectural style is characterized by features such as rounded arches, thick walls, and simple large-scale forms, which can be found in churches, monastic buildings, and cathedrals throughout various countries, indicating a shared cultural and artistic language.

During the Romanesque period, art and architecture began to flourish, combining elements from various regions while maintaining a sense of unity through these characteristic features. This style set the foundation for later developments in Gothic architecture, which emerged later and also enjoyed significant international diffusion but was more specific to certain regions and evolved from the Romanesque traditions.

In contrast, while the Gothic, Baroque, and Renaissance styles also gained international attention, they emerged later and were influenced by different cultural and artistic movements that followed the Romanesque period. These styles differed significantly in their architectural structure, decorative techniques, and underlying philosophies, marking a progression in the evolution of European art rather than a revival of an art movement that had a widespread, cohesive formula as seen in the Romanesque style.
