What year is associated with the beginning of the High Gothic period?

The High Gothic period is generally associated with flourishing artistic and architectural developments in Europe, particularly in France, from around 1200 CE. This time is marked by significant advancements in the design of cathedrals, such as the use of flying buttresses, which allowed for taller structures and larger windows filled with stained glass, enhancing the illumination of the interiors. Notable examples from this period include the cathedrals of Chartres and Reims, which exemplify the intricate design and spiritual aspirations of the era.

The other options represent periods that either precede or extend beyond the High Gothic, making them less relevant to pinpointing the start of this specific artistic movement. The 1100s reflect the Romanesque style that preceded High Gothic, while the years following 1250 saw a gradual transition towards the Late Gothic style. Thus, 1200 CE is recognized as a pivotal point marking the emergence of the High Gothic period in architectural history.
